Get creative, save the planet!

To help save the planet from climate change, people need to get creative. Look at these three innovations that people have made to create a cleaner, greener planet:

Seed drones

COP27-ThinkingQuestion-Banner

These drones can plant up to 40,000 trees a day. That’s a lot more than one person could do!

The SeaBin

COP27-ThinkingQuestion-SeaBin-Banner

The SeaBin is a unique device that removes plastic rubbish from the water. It acts as a floating ‘trash can.’

Smog Free Tower

COP27-ThinkingQuestion-SmogFree-Banner

This tower uses special technology to suck pollution from the air so people can breathe cleaner air. We think it looks like a piece of art too!

  • I love the smog free tower, I think its the most useful for curbing the most prominent form of pollution. There is nothing more precious than breathing fresh air especially at the beginning of a new day. It reduces the number of premature deaths each year and puts a hold to pollution. I've had an idea on bio perfumes made with organic matter from trees.

  • My community suffers from a lot of air and land pollution and I recently learnt of how artificially made perfumes cause huge problems in contaminating the air so why not go natural with plant based body mists that does very little or no depletion to the ozone and focus more on robotic trash cans that reduces the cumbersome task of heavy duty trucks handling waste that give of harmful fumes.

    1. Your point made me thinking, however at this point, who do you think is the first party to have the responsibility to action upon this situation? Consumers, Manufactures, Gouvernement?

    2. I agree because vehicles in my country cause a lot of air pollution that is not good for both the ozone layer and we humans. And we need devices like the smog free tower to clear the pollution in the environment.so I would love to recommend it for my country

  • I'm going to create a device that is an interactive trash can that gives users bonus points for everything thrown into it. The outside of the bin consists of motion sensors that react to throwing things inside to motivate people to throw rubbish into bins and I'll call the device the Smart Trash.

    1. This is a nice idea agreeable_dusk. I wonder how you could show the point system? Is there a way of making sure people don't throw recyclable items into it?

    2. Hi agreeable_dusk! What an innovative idea! What could users do with the bonus points they earn?

      1. They can collect as many points as possible and therefore the one who collects the most points will be rewarded so as to set an example for others

    3. That is a great idea! Have you thought more about how this could be integrated in cities? What would the bonus points lead to for example? would there be a way to make sure the rubbish is segregated into respective bins? great idea that you should definitely keep thinking about! Would love to hear more!

      1. Well, this can be combined with cities. If we see the success of my invention in my country, I will invite the heads of the cities and explain the method to them, and this has benefited my countrymen and led to the preservation of the environment.

    4. This is an amazing idea! What would the points end up being e.g. what rewards would you give to people who picked up the most rubbish?

      1. Since we live in developing countries, I will give them a bonus, which is free shopping in the supermarket of vegetables, fruits and other things, this helps to meet other needs and maybe I will think of another reward

        1. Hello again agreeable_dusk,

          I already thought the idea of interactive trash cans with bonus points was a good idea - but your further suggestion to use those points for free produce at the supermarkets is brilliant! It would give homeless or hungry people an opportunity to help tidy the streets in exchange for food. I think you should keep developing this idea, well done!

  • When I was reading the question what came to my mind was Kaduna state and other states in Nigeria whose farms are being destroyed by Fulani herdsmen and their cattle. When the Fulani herdsmen and their cattles attack and destroy the farms, the farmers have nothing to harvest causing the food system to go low and there wouldn't be food for people to eat causing them to starve. What my creative mind thought about was a robot that could protect the farms from attacks and chase the Fulani herdsmen and their cattles away. The robot would be powered by solar and when they come to attack the robot would be programmed to fight them back.

  • The invention that would make a difference is the Smog Free Tower I chose because it gives an immediate result that purifies the air directly and not like seed drones. The tree should grow to purify the air and there is a possibility that it will not grow, but it is important in the long run.

    I personally suffer from the problem of bright lights at night, especially at bedtime, and since my brothers are young, they are afraid of the dark and light up the lights. This is my personal problem, but if we think carefully, it is an environmental problem as it disturbs the animals' sense of night and day, which reflects the biological cycle and causes In exhausting many insects that are often from pollinating crops in the region, thus the lack of agricultural crop and on the human level caused it (dwarf) or lack of secretion of growth hormone. Its light corresponds to the light that animals can tolerate. I want to name my satellite (the Moon of Life). I chose this name because it will preserve the natural life of animals, plants and humans.

    1. It's really interesting that you mention light pollution - I also think it is a major concern, and it doesn't get as much attention as other issues such as climate change, air pollution, and waste. As you mentioned, it affects human and animal health, and I'm impressed you considered the second- and third-order consequences, such as the effect on crop pollination - many of the issues the world faces now are due to short-term thinking that doesn't consider the big picture.

      How would your Moon of Life satellite work?

      1. I think you know the light absence circuit. I would like to make it like a light absence circuit. We put a light sensor in it, so it senses the light, and in the absence of it, it lights up, and since it will be close to the sun in the day, I want it to work on solar energy, where we put solar cells on it and it is like a round body It is full of dimly lit lights and the color of the body is white so that it does not appear much in the day. I would like it not to rotate, but rather to be in one area, so it will be suspended in the airspace, and thus the possibility of it falling or disrupting it is less.

  • I see that the three inventions, each one of them is no less important than the other, but drones will lead to solving two problems, the first is to reduce the problem of hunger, so it can be used throughout the countries that suffer from this crisis, and the second is if the green spaces increase, the air pollution will decrease. These solutions will not be holistic, but rather Relativity would be a very useful invention.
    For me, the area in which I live is a conflict zone. There is no stability or security from all sides. There is a problem that we have been suffering from for 16 years without electricity. I see the use of solar energy or the sea to generate electricity. It will be the best solution and it will not be harmful to the air and air, and the invention that can benefit the world. I see that it starts from Peace, peace will lead to a normal generation that will be able to invent and excel, but in the shadow of wars there will be no creativity

    1. I agree with you on some of the things which are the positives of the seed drone. But I do not agree with you that it always has positives, it also has negatives. For example, when we rely completely on this plane, we will dispense with labor and will depend on technology. This will negatively affect us, and when we reduce the workforce, unemployment will spread, and when unemployment spreads, poverty will spread. We cannot rely completely on This plane, so we can use this plane in some times when the workers are on vacation, so we save time and effort and do not spread poverty

      1. You make a really interesting point about the connection between automation (robots, drones, artificial intelligence) and the workforce. But many experts think that automating some work, like planting trees with this seed drone, could free up people to do whole new sorts of jobs and work in new industries which are also being created by these new technologies. Do you agree?

    2. You have made a very interesting point cooperative_sea. I agree with you because I also think drones are very important and they perform lots of functions. They can help to reduce hunger, and they also help to reduce air pollution because more trees will be planted and the air will be less polluted. In my opinion, drones are also performing the work of the Smog Free Drones as they also help to make the air clearer and more pollution free.


      My community suffers from pollution. There is a lot of waste around mostly organic waste such as cow dung and when organic waste is left unattended, it secretes a liquid called leachate, and two main gases: methane (CH4) and carbon dioxide (CO2), both of which are greenhouse gases. These gases contribute to global warming which leads to climate change. I want to create a machine that converts organic waste to biogas and the residue can be used as fertilizer. I would name this device, "Operation: Waste Free". I am currently learning the basics. I am working with my physics, Chemistry, Biology, and Programming teacher so that I can make my dream a reality.

  • One of the biggest problems that my country faces, and not only my country, but the whole world suffers from it, is electronic waste, as there are many wastes that are not exploited and cause big problems, and I suggest making a robot that works to separate parts of electronic waste from Sensors, iron and copper and use it with other new things to take advantage of them.

  • Due to the high water shortage in my country as a result of bad use and waste of water, I will invent a water shower that monitors the amount of water we use or need. When we use more than the amount we should, the shower lights up strongly in order to warn the person to get out of water when there is an excessive use of water. It also can minimize the size of water drops, as well. I'll call it the smart shower.

    1. This is a great idea agreeable_dusk! I wonder if you can use your problem solving skills to figure out who you would need to have in your team to make this happen?

      1. There a number of particibants I need in my team to implement the idea. A civil engineer, and a mechanical engineer can design, apply, check the applicability and feasability of the smarter shower. An e_marketing especialist can be responsible for marketing the product in local and international markets. Also, members of the local community and water municibility are needed to raise awareness towards the issue of the rational use of water amount.

    2. Do you have any plans for this smart shower of yours and when do you intend to bring out this invention to the world.

  • The seed drone might make the biggest difference because if we are to use these drones, the rate of planting trees shall increase of which these trees first of all, they will absorb the bad air that's to say carbon monoxide which destroys the ozone layers hence to climate changes like global warming and planting trees shall prevent this. Still when we use these seed drones to plant trees together with crops(agroforestry) , we are increasing soil fertility meaning production of more food crops solving a problem of low food production. So using seed drones is a method that can be used not only to solve climate change due to pollution but also hunger due to low food production

    1. You made a very interesting point lovely_language! I love your idea. I agree with you. The seed drone will be very useful to humans in the coming future. We will be able to plant many more trees with it. Where I live, there are usually problems of fighting and insecurity and that is why I feel like to improve the seed drone, it should be automated and turned into a robot. Overall, it is a really good invention.

      If I was to create a machine it would be a machine that turns organic waste into biogas and fertilizer. The area I live in has high a high pollution rate and if these waste are left unattended, they release dangerous gases such as methane which can deplete the ozone layer, leading to global warming and climate change. So creating this machine will be part of my own contribution to creating a more sustainable environment and stopping climate change.

  • I see that all these innovations are very useful, but I think that The SeaBin's innovation is one of the best, as it solves more than one problem at the same time, which is the collection of plastic waste from the sea, and works to provide a safe environment for the life of marine creatures And it works to save the lives of those who clean beaches I see that the solution is to unite the governments and support them to each other, without causing any wars and reducing political rivalries.

  • All the inventions mentioned above are important and useful in my city Gaza . But I will not choose seabins because it needs electricity and here in Gaza we are suffering a lack of electricity .In addition many fish get caught and discovered with plastic inside of them each year.

    In Gaza , solar cells is very important invention which transform energy into electricity from the sun .solar cells never run out of electrons .They are getting energy from sunlight So it often generate electricity which can reduce electricity problem in my city .

    1. This is an interesting example to hear about brave_forest!

  • maybe we can figure out a way to use less paper for school book and drawing e.g. we could change it to a type of plastic the when a factory puts a certain amount of heat and pressure to it it would act like paper but we would have to make a plastic that would do that

    1. Some creative thinking here persistent_weasel!

    2. Hi @persistent_weasel! Figuring out a way to use less paper in schools is a great idea! Do you think using plastic is the best solution, or can you think of any other ways?

      1. maybe instead of plastic we can use fruit skin but we put it through some liquids and that would make it easy to write/draw on and would not rip. It would not be a lode of different types of colours as we would add white or blue dye so its easier to see

        1. Hi persistent_weasel,

          Good answer! Using fruit skin would definitely be more environmentally friendly than using plastic!

  • In my view,the seed drones might have a big difference on the world cause as they help reduce temperatures,reduce the amount of carbondioxide in the air through photosynthesis and release more oxygen into the air.They also increase the amount of rainfall received.In other words planting more trees can be a source new jobs for people forexample taking care of them,operating the drones,making seeds ready for planting rather than industrilization that creates jobs but also pollutes the air and water bodies through disposal of wastes.

    1. daring_ cherry thanks for your comment. Do you think trees will be looked after by machines in the future too?

      1. Not exactly because these machines need to be run by people so as to do a good job in looking after the trees. Although machines can do job faster, we are needed to guide what they do on our behalf.
        Thanks for the reply

  • I would make a flying machine that uses solar energy and flies in the air and pulls plastic into t would crash them and store them so as to be recycled later on. This would help solve the problem plastics that pollute the soil in my home area.

  • Due to high electricity usage in my country "Uganda" I would invent a gadget that can measure the amount of electricity used in per hour and then you can customize it and set a limit of power like a home can use in a day and if a family uses more than the given amount of electricity used in a day it turns off the power which helps to reduce on the electricity usage or it can reduce on the electricity like when some parts of the house don't have power to minimize on the usage and I will call this "The electricity limiter"

    1. Measuring the amount of electricity being used in a home is a great way to improve energy efficiency by increasing personal awareness for managing usage. It's interesting that you would use it to set a limit. Can you draw out the pros and cons for limiting electricity in this way, and are there other ways that measuring energy usage can help create efficiency?

  • The invention that might make the biggest difference to the world to me would be the seed drones that can plant 40,000 trees a day and that is more a one person can do. The reason why i chose this over the rest is because as to me the rest have like only one importance or way that they can help us but this one has many ways it can be useful to us this is to say;
    1. RAIN FORMATION: These trees that are planted by the seed drones help in rain formation and rain formation helps to support plant growth or crop growing whereby people earn money, food all from crop growing.
    2. BEAUTIFYING THE ENVIRONMENT: These trees help to beautify the environment which attracts tourists to come into a country increasing the the income/revenue of the country.
    3. PURIFYING THE AIR: These trees help to purify the air whereby they absorb the the harmful gases produced by the industries that may lead to desertification so instead of using the smog free tower we can use the seed drones to help with the air pollution problem.

    But I think that we should also think of another invention that help with the land pollution problem whereby this device will help us remove the wastes on land and I would name it The Land Can.

  • The three innovations are very important in saving the world. Each innovation has a special mission. The seed drone facilitates the cultivation process and does two things that give oxygen to the environment and work to soften the atmosphere and also saves time and effort. The second innovation will help this invention purify water from waste, so it will not pollute the water or the aquatic environment. The third innovation This innovation is very beautiful and strange at the same time. When we look at the idea from the outside, a question comes to our mind, which is how does this tower work? How can the air be purified? This idea is beautiful and I think that it will provide a safe environment for human living. In my opinion, this tower should be provided all over the world. I think that all the following inventions will save the world, but we must develop them because they have negative effects that may affect the environment. The problem in my environment is the problem of sewage that spreads in the streets during the rains. This is a problem that hinders traffic in the streets and hinders our passage while we are on our way to go to school. To drinkable water, we reduce the sewage that fills the streets, which when the situation swells, they put in the seas, polluting sea water and polluting the environment as well. Therefore, I suggested that I make the name of this invention “water filter.” We can put it in the infrastructure and create an infrastructure designed to filter water and this The problem is not only in my area but I think it is all over the world

  • The seed drone might make the biggest difference to the world since it can plant 40,000 trees in a day meaning the number of trees shall increase of which these trees help in rain formation through a process of transpiration and when rain is formed it helps water crops increases on their yields. Some trees bear fruits which can be eaten and this can keep one healthy. Trees also help to reduce air pollution like factories can produce smoke which is scientifically called carbon-monoxide which can also destroy the ozone layer exposing the earth to the sun and that can lead to global warming. Trees also provide shade where one can settle under it incase it is too hot.

  • Okay I Love the idea of the drones, In this case its prominent cause it helps in absorbing toxic fumes in the environment because i think every one loves living in an environment with fresh and clean air, and this will also reduce on the number of diseases that are caused due to the toxic fumes put in the air and it also stops air pollution .I had an idea of creating industries that don't produce toxic fumes.

    1. Hi original_lobster. Great idea - what industries would you begin with?

  • منThe invention that will make a big difference in the world is the seed drones, because these drones plant up to 40,000 trees per day, and this is a great achievement that humans cannot do, and the trees benefit us and the environment. Carbon dioxide and trees absorb excess water on the ground to prevent deviations. It is possible to invent a machine to regulate the streets in just 5 minutes. I think this could be a wonderful invention. I suggested naming this invention (making the environment better) and also making cars and electric bikes to walk on Electricity system to save diesel and gasoline

  • Drones seeds I think that they are the best that can happen in our country because they help us in farming without farms, faster and more abundantly.

  • I thought of an invention that can solve an environmental issue in my area. The invention would suck out the dirt's from lakes and my invention would be able to filter the water too. The invention would be called dirt sucking and filtering machine. In Nigeria, the water bodies are polluted with plastic bags, plastic bottles, cans, industrial waste, pesticdes and so many other waste. The machine would be placed under the water body to suck the dirt's and filter and anytime it's full it would be emptied and disposed properly after the dirt's are disposed it would be placed back in the water.

  • In my opinion (seed drones) since it plants 40,000 trees a day, you will ask me why I chose it? Because trees also purify the air, taking in carbon dioxide and giving us pure oxygen that is suitable for breathing If we plant 40,000 trees in every region of the world, we will benefit from two things, the first is that the air will purify and we will take in oxygen
    The second will solve the food crisis

  • We can invent air purifying fans that take in the dirty air and purify it and give us clean air
    How will you help us? or why Did I choose the fan? I chose it because it is fast in drawing air and returning it. If we make this fan, we will put a fan in each area, and it will purify the air in that area, so it will become cleaner air.

  • In my country, Palestine, yes, there are springs (tanks) of free drinking water. In every area there is a tank, either one or two.
    Of course, there are some options for reuse and recycling, for example, in my country, they reuse straw into straw bags.
    And the crockery
    They reuse old dress fabrics to make vases and art pieces

  • I think the three innovations, each being just as important as the other. First, the SeaBin is a unique device that removes plastic waste from water. It can provide a safe environment for the life of marine creatures and save the lives of sea creatures. However, I would not choose SeaBin because it needs electricity which is not totally available in some countries. The second brilliant innovation is drones which plant trees to to maintain gas balance. It also provides food for humans. I would choose this since it can solve two global problems of climate problem and food shortage in the world.The third is creating a tower without fog that seemed like a piece of art. However, it is un applicable in all countries. For instance, it is unapplicable in some contexts of conflict, high costs, the lack of large areas, and high population.

  • They are all important because they are all beneficial to humans, save time and effort, and make our lives easier, they all make a difference in the world.The drone that operates the seeds contributes to increasing agricultural production and saves time and effort for farmers and helps the poor Sebeen removes waste and keeps streets and places clean, and the tower Smoke-free makes us breathe cleaner and better air, resists air pollution and prevents the spread of diseases and viruses I think there will be an invention for travel, so that traveling from one country to another is faster, flying faster than the speed of light can be invented to facilitate travel Or you can invent a device that lights up when you shower when you The water temperature is right I can call it a shower light

  • Each one has it's importantance , but what I liked about these inventions and what I think will make adifferenceis is the smog-free tower because the problem of pollution does not suffer from one or two countries , but the whole word and this due to human misuse of the environment , but let us stop for a while and imagine the beauty of our planet without pollution ?! It will be awonderful feeling and will be beneficial for everyone from a person to a plant or animal,and in my opinion it may be a great idea to build these towers alot because of the benefits they contain and an amazing aesthetic view.

  • The problem that I see is that my town often suffers from road congestion and we as school students find it difficult while crossing the road and this happens because there are no traffic lights and pedestrian paths.It might be a great idea if we set up traffic lights that work on solar energy because we suffer from frequent power cuts.

  • In my opinion, the smog free tower is the one which is going to make a very big difference to the world because air is life and this machine cleans air .If you do not breathe in clean air, what would you like to breathe in, dirty air? because dirty air causes diseases while clean air promotes good health.
    The invention I would like to come up with is a machine that picks rubbish on land because some people have refused to pick it up.

  • I think that The SeaBin is the best invention.This is why I think that seabin is the best invention.Sabin will hpal sea animals to live longer by not eating plastic.Turtle will stop gat suck in plastic.but I want to know how many plastic thay clerk and what they dorn wef the thrash.They invention i would make well be stop fires to spread.

  • Due to the high prevalence of diseases and viruses in my country, I will invent a device that is a bag that consists of a self-sterilization system and removes unpleasant odors, where the bag sterilizes any clothes, shoes, or anything placed in it automatically to protect ourselves from diseases and I will call it the smart bag

  • Barbecue parties, or restaurants that depend on natural coal, are a deadly source of carbon emissions from coal and are harmful to humans and the environment, so I will help my local community to overcome this problem by creating a solar stove, which consists of reflecting mirrors that heat thin aluminum tubes at the bottom of the stove Which in turn will heat and grill meat and cooking, so that we can preserve the environment and our health, and I will call it the eco-stove..

  • see that all inventions are suitable for the world and solve many problems, and I see that the second and third inventions will greatly help in reducing the proportion of pollution and waste in the world, as we know that as we advance in time, we waste and pollution will increase more and more.

    I found that many people suffer from diseases caused by spoiled food that contains preservatives, toxins, microbes, fertilizers and pesticides, and I found that this invention will greatly help in solving this problem. It is a machine in which the thing we want to eat is placed and tells us that it is healthy and must be eaten or not, and whether it has any harm to the body and what it is, and warns us not to eat it or buy it again. I will call this machine “the friend of healthy eating

  • I have three questions. How will this drone work as if it burns fuel, then it is not good for the climate. My second question is, where will the seed drones plant as I know a few places / countries where you are not allowed drones and thirdly, where will the money come from to make or buy the seed drones? I think if we are going to buy the equipment to make this invention, maybe we can fundraise for it?

    1. Great creativity in think about some of the potential problems here!

  • -Are the stars we see at night made of rocks?

  • I think they are all important to the world, but from my point of view, I think the most important one is the smoke-free tower. And the most beautiful is to inhale clean air, and clean air is the basis of life, and some people may suffer from allergies to polluted air, so they must be provided with fresh air, and this has negative effects on agriculture as well, so it must be provided in most countries that suffer from pollution.

  • According to my view, all inventions support the cleanliness and health of the environment, but for me the third invention may make a big difference in the world because it helps to preserve the environment from air pollution and not only preserve the environment, but also preserve the health of the respiratory system in humans, so I support it I created a talking trash can that looks like a robot, and when a person throws trash on the ground, it speaks and says that the person puts the paper in it, and it is also a stimulus to put waste in it because it may be a new innovation

  • I see that all of them are useful for nature and for its protection, but I saw that the first innovation is very useful because it saves time and effort, and also sometimes it is difficult to work in agriculture where the worker is tired, so this invention will be easy for everyone. I also liked the third (last) invention because it purifies the air and is good, especially in areas where there are many factories, so I highly recommend it. I will create a device that looks like a wristwatch and every person wears it, and this device will emit a sound when a person goes to an area where there is less oxygen until you alert him to this, and it will keep making a sound until he comes out of the place so that no harm will happen to him, and I will call this device the watch of life.

    1. Wow what a brilliant idea for an invention eagar_atom!

  • I liked the idea: the seed drone is amazing because it targets agricultural lands where the farmer cannot plant these huge numbers of trees.
    So, my friends, we can plant these enormous trees close to each other, just like a forest because Contribute to: 1_ Preventing soilerosion
    2_Keep the soil cohesive
    But without trees and forests, the soil becomes more exposed to the sun and erosion that leads to drought
    3_ And do not forget that trees are the first factor in purifying the air, as they withdraw carbon dioxide and provide us with the oxygen necessary for the breathing process.
    "Seed plane is a solution we will target soon"

  • Which of the above inventions may make a big difference in the world? Why? Inventing planted drones because they save time, effort and money also because you will need workers to do seed planting so you will need money and also not too tired and useful for farmers and because food is very important in our livesDo you have an idea of an invention that will help save the planet?
    Yes I think this invention is beautiful and also useful is smart clothes that can change thickness by temperature and be heavy in the cold and light in the heat of the sun.

  • 1 Each of these inventions, according to me, is of great importance, no less than the other, but I will choose the product that will solve the problem that my country suffers from. I will choose the device for removing waste in the streets. I see garbage everywhere, and this causes pollution in the soil and in the air, and it is not appropriate. If we can With the presence of this invention, the streets will be beautiful and will leave a good impression in the city. If there is no waste, the pollution will decrease, and in return, the air will be clean and the soil is good, and there is no plastic waste, so the soil will be suitable for agriculture, so if this product is available, it will save the world. It is very wonderful .

    2 Let me invent something for my town. Here, there is pollution in the air because of factories and carsSo we keep the air clean and I will give it a name (air cleaner) because it will solve environmental problems all over the world and not just in my town I think people will love it.

  • According to my point of view, here in Pakistan the SMOG is more dangerous then CORONA VIRUS OR EBOLA VIRUS 🦠, Because the consequences of SMOG are very harmful for human body as well as other creature on the surface of earth. I will be designed a SMOG and SMOKE absorber unit at small level to measure the efficiency of this device. If the the out out is effective the I will develop at large level to Save earth.

  • On my opinion, all the three inventions are all very good in their ways. The drones will lead to solving 2 problems and also create its own problem. The first is to reduce the problem of hunger, so it can be used throughout the countries that suffer from this crisis, and the second is if the green spaces increase, the air pollution will decrease. The drone will consume fuel and will release carbon monoxide to the environment. but in the other ways it is useful. In my area we have been suffering with the problem of flood and strong wing but when drones plant trees that will aid in breaking the strong winds. My invention will be unity and love because if people love each other there is peace in the world and unity will make people love each other

  • I believe that the seed drone will make the biggest difference as it can plant loads of trees in one day and it will still let us cut down trees to get paper. (new trees would replace the cut down trees.) My idea is an animal lover machine that brings female and male animals together (different species) so we can have more animals. (Not to kill.) With that idea it would stop when enough animals are in the wildlife.

    1. Great ideas educated_tree!

  • I think that the tower technology for air pollution is the most useful technology in conjunction with the increase in pollution and technological development on climate change, especially in factory areas and animal pens, especially pigs and cows, which emit carbon dioxide.

  • We can't deny the significance of each invention , each one work on a different element .Seed drones helps to make our planet greener which means cleaner air and decreasing the impact if the global food crisis by increasing food production. While the SeaBin makes our earth's water bodies clean and suitable for marine organisms. I think Smog Free Tower is very useful and necessary one because it purify the atmosphere from the carbon emissions which cause the climate change. Due to the excessive use of fossil fuels and natural gas in our communities like gas stove in our homes, we have to invent cooker which can work using the solar energy to decrease the uses of gas which affects our climate badly.

  • Climate change has become the issue of our time. Everyone is now experiencing major changes in weather patterns, and hearing about increasing sea levels that scientists predict will cause catastrophic floods around the world, threatening food production. There are a lot of things we can do to help... Preserving the planet such as planting trees, conserving water, saving energy, giving up plastic, saving resources, reusing and recycling

  • In my opinion, the inventions mentioned above, each one is no less important than the other, but the drones have the greatest use in military purposes such as surveillance and attack, as well as in civil works such as firefighting, and monitoring pipelines, and are used in difficult and dangerous tasks for the traditional aircraft that must To be provided with the needs of the pilot, and getting rid of all these needs reduced the weight and cost of the plane, and I led others. This plane is a natural air war, so that the control of the plane is not exposed to any real danger. From all sides, there is a problem that we have been suffering from for a long time, which is the water crisis, which led to a decrease in the amount of drinking water, and led to fluctuations in the quantities of rain water from year to year, and unbalanced consumption. I see desalinating ocean water and launching awareness campaigns and rationalizing water consumption. It is the best solution to avoid a water crisis. And I have a question, which is from the money coming to make or buy a drone???

  • A balanced use of all the three is needed for the drone would help mitigate global warming and carbon footprint.The Swan n would keep water clean and the Smog free tour would keep air clean .the key components of nature are taken care by this .
    I would like to design a device that can take multiple data related to environmet at different places and analyse the same and suggest most effective solution usking data analytics

  • "Which of the above inventions might make the biggest difference in the world?"

    From the above inventions, I think " Smog free towers" can make a change in our world because as you mentioned: these towers absorb pollution from the air, so people can breathe cleaner air and you have a point they look like a piece of art...
    " Smog free towers are inventions designed as large-scale air cleaners, which reduce air pollution particles. The world's first " Smog free tower" was presented on 4th September in Rotterdam, the Netherlands, by Daan Roosegaarde and his team. This extraordinary invention is successfully implemented in: China, Poland, South Korea and Netherlands. But, unfortunately the filters of the "Smog free towers" are unrecyclable..." ~Wikipidia.
    I chose the "Smog free towers" as air pollution is one of the biggest threats to the humans' health, that leads to: lung cancer and heart disease. Also, air pollution damages buildings and haze or smog can decrease the range of vision. The causes of air pollution are: burning of fossil fuels, wildfires ( due to the global warming), industrial emissions and so on...
    Everything in this world has pros and cons, so does the "Smog free towers", one of the major disadvantages of these towers is that their filters are unrecyclable, so we should take this point into consideration, as it going to affect the landfills... A lot! Plus, the cost of maintaining these smog towers is very high...
    I believe, if every single city had at least one " Smog free tower", we would have cleaner air... But, what about the developing cities/ countries?
    The developing cities/countries can also help to reduce air pollution, by: reusing, recycling, growing gardens, providing cleaner fumes and much more...
    In conclusion, I think that "Smog free towers" are great inventions to reduce air pollution, that can make a difference in our world...
    Thank you! :)

  • I think The sea bin is a great invention because it will help clean the ocean and it will help all the aquatic life. Sometimes we forget about all the rubbish in the ocean especially if we don’t live near an ocean. We don’t see the harm it causes all the animals. It will help our animals to live longer as all animals in the ocean are important. So much rubbish ends up in the worlds oceans.

    1. Thanks for your comment@terrefic_tornado. What different solution you could think of to keep the oceans clean?

      1. I think that there should be little sea bins attached to all boats that would travel around the oceans and help to clean up all the rubbish.
        There should also be stricter laws and regulations about dumping waste and rubbish in the seas. They should not just be fined but have to to do something to improve the cleanliness of the sea or the fines should be used in projects that help to clean the seas.
        More money should be invested in projects that could help to improve the cleanliness of the oceans.

        1. Really original ideas terrific_tornado! I really love your point about fines being ineffective and instead being replaced with initiatives to improve the cleanliness of the sea. You have shown great creativity, well done!

  • What worries us the most is pollution and the rise of fumes and gases from factories and restaurants. I will create a gas filter to be placed at the gas outlet to separate and purify it and reduce the rate of its rise into the atmosphere. And taking advantage of carbon gas in the medical fields and treating tar, in addition to stimulating the growth of some plants inside greenhouses, such as cucumbers, and used as ice to keep food pure during transportation.

  • I sincerelly agree that all 3 inventions will solve one or the other world crisis, whereas, the drones will iminently solve the issues which: The SeaBin and Smog Free Tower will do to provide succor to the world.

    The Smog Free Tower.
    The smog free tower will aid humanity in many ways, whereas, to recieve the items needed to make this invention; it requires various materials to be exported to other countries via cargo ship (which is already not beneficial for the environment). Furthermore, air pollution can be solved in numerous ways and the major pollution currently occurring is plastic pollution.

    The SeaBin
    With the SeaBin already recieving an up, it is beneficial as it is doing something to help one of the main crisises happening to our Earthly ecosystem. Whereas, there are more things that we can do to help.

    Seed drones
    Seed drones may require mounds of money to buy the multitude packages of drones but it will firstly reduce the problem of hunger, so it can be used throughout the countries that suffer from this crisis, and the second is if the green spaces increase, the air pollution will decrease. This will help everyone

    To conclude the invention of seed drones is the best idea to go along with.

  • Due to high electricity usage in my country "Uganda" I would invent a gadget that can measure the amount of electricity used in per hour and then you can customize it and set a limit of power like a home can use in a day and if a family uses more than the given amount of electricity used in a day it turns off the power which helps to reduce on the electricity usage or it can reduce on the electricity like when some parts of the house don't have power to minimize on the usage and I will call this "The electric limiter"

    Though it also has its pros and cons then the pros of limiting electricity in this way are; it can help one to know how much energy they have used, it helps one to save power, it alarms one incase they have gone over electricity limit they have set.
    Then the cons of this way of limiting electricity are; Incase of a power outage it also stops functioning this means it works on power, it also uses a bit of the electricity.

  • I think the smog free tower is a is an amazing idea, because so many people drive cars, motorbikes and smoke cigarettes. That smoke is polluting our air so the idea of smog machines are great as they can suck all the polluted air and filter it so it clean air. If I were to make a new invention to save the world it would be a water bottle is non toxic and reusable as lots of people around the world use single use plastic bottles. Also maybe if we had a vending machine that would pay you back half of your purchase for the item you bought that machines in more places.

  • I love the sea bin because sea bin is a device that remove plastic rubbish from water last year me and my family was go to sea where I found a turtle which was caught in rubbish and we free them so I feel that many people throw plastic rubbish in sea and water that are very harm to aquatic life so seabin project is so good

  • Due to the high water shortage in my country as a result of bad use and waste of water, I will invent a water shower that monitors the amount of water we use or need. When we use more than the amount we should, the shower lights up strongly in order to warn the person to get out of water when there is an excessive use of water. It also can minimize the size of water drops, as well. I'll call it the smart shower.

  • In my view , I see that all inventions are of great importance and we need them a lot to help us in our lives , but the invention of a tower interest and controversy more because in my country there are many pollutions caused by factories and car smok .
    There are many diseases that affect humans , animals and plants , which leads to a weak economy .

    1. @frank_papaya what your solution will be to reduce the pollution in your city if you were mayor of your city?

      1. First, I move factories away from residential areas, and instruct people to use bicycles instead of cars to move between cities because they are less polluting to the air, and I plant a lot of trees because they work to purify the air from pollution .

  • The drone technology seems to be more one of innovative way to curb the air pollution. Moreover, there should be urge to plant trees which have the tendency for more pollen spreading - like paper mulberry trees in Islamabad - and having tendency speedy growth elsewhere.
    Sea bin also can be an effective tool to clear sea water from pollution in the countries having coastal areas and islands. Ormara beach in Pakistan is found polluted due to negligence of the public.
    The smog free towers are the need of the most pollutant cities like Karachi and Lahore.
    I think the most immediate need is to educate people - to make them able to keep the environment clean, understand the impacts and the importance of clean atmosphere and environment - along with the use of innovative technologies.

  • I think that all of them are useful and all of them are very necessary in each region because they help both farmers and others.

  • I think that all of them are necessary and useful in all areas because they reduce time and effort.

  • Everything in this world has its pros and cons, and like a seed drone, it has its pros and cons. One of its advantages is that it saves time and effort and helps plant the largest possible number of seeds, but it has its downsides that if we rely on it, poverty will increase as a result of the spread of unemployment and the lack of job opportunities, because agriculture in my country is very important and provides job opportunities. In my country we depend on groundwater, and our frequent use of it helps in the gradual depletion of groundwater, so I want to devise a device that works electronically so that I can store and hold water when it rains, and it must also be able to desalinate water (sea and ocean water) and I think it should To call it an electronic water purifier

  • All the above innovative ways to reduce the climate change effects and pollution are wonderful. The university students (technical fields) should be encouraged in such countries to come up with more such inventions. For example in Pakistan, there was news on digital media - about some students from NUST, Islamabad - who have managed to build a car running with electricity instead of petrol, a step forward to reduce air pollution. I will simply say:
    1- Educate people about pollution and its effects.
    2- Reduce pollution by applying green technology in brick kilns and other industrial sectors.

  • Me personally, I would say the "Seed Drones" or "The Seabin" would make a big difference in many of our environmental problems. I really can't decide between which one of the two would be more impactful because both are really good. The "Seed Drones" would be good because we need trees to clean our air and to breathe o2/oxygen. The "Seabin" can make a difference because there are a lot of trash people left on the beach and waves pick it up. But then we have the "Seabin" that removes plastic from the ocean. It also helps because the animals get trapped in plastic bags, plastic can holders, and straws in their nose. I would invent robots that vacuum the city or clean the city using Litter Pickers because in our environment there's a lot of litter in the streets. I thought of that because we have a lot of sea devices to clean the sea and not that many land cleaning devices. I would name it The Cleaner Agent, I would name it because it cleans the street and it looks like they are doing business that's where the agent kicks in.

  • I see that the three inventions, each one of them is no less important than the other, but drones will lead to solving two problems, the first is to reduce the problem of hunger, so it can be used throughout the countries that suffer from this crisis, and the second is if the green spaces increase, the air pollution will decrease. These solutions will not be holistic, but rather Relativity would be a very useful invention.
    For me, the area in which I live is a conflict zone. There is no stability or security from all sides. There is a problem that we have been suffering from for 16 years without electricity. I see the use of solar energy or the sea to generate electricity. It will be the best solution and it will not be harmful to the air and air, and the invention that can benefit the world. I see that it starts from Peace, peace will lead to a normal generation that will be able to invent and excel, but in the shadow of wars there will be no creativity

  • To save the planet from climate change and pollution, we should always take appropriate measures whenever we can. The above three examples are really excellent and I love it. I got an idea of inventing a machine which would prevent emission of excess of green house gases from factories. This machine will start to alarm if excess of green house gases are emitted. The government should create law that only this much amount of carbon should be emitted per day and this should be followed by all the industries. I would name this machine as THE EMISSION WARNER.

  • I thought a lot and came to an idea, which is the problem of wastewater in my country. The government disposes of wastewater in the Mediterranean without using it because of the economic conditions in my country. We can solve this problem by treating the wastewater and using it in agriculture as fertilizer and pure water for human uses. At the same time, we are It may help us solve the problem of sea water pollution. We preserve the environment and keep the fish wealth clean, and at the same time, we compensate for the amount of water stolen by the occupation to compensate for the lack of groundwater due to the lack of rain.

  • I think if we had technology that clean the air pollution in the air that will be so good for the world but best for mexico because they have the most pollution.And it will help with giving out good air for when your house have a stink smell or a nasty smell .Do you think this will be a good item for the word?

  • I think the Smog Tower is a good idea and invention because it makes the world better air for people to breathe and live with,especially for newborn babies.The Smog Machine is a good safe idea for us people to have for people to live with it is awesome and I like the idea.Should Scientist make a infinite Tree container?

    1. What's an infinite tree container? Sounds like a great invention - do tell us more!

      1. The infinite tree container would be a futuristic tree in a container and sense tree's help us breath then the infinite tree container is a container is that is pretty much connected to you and the container is a more bigger thing then a oxegen tank

  • I'm going to create a device that anytime that it see's trash it will automatically pick it up and put it in a bin i will sell it for probally 200 dollars and it will be the best invention in human kind. The mechinary i will use is metal plastic and carbon fiber it will be the best macherny ever

  • Im Going To Create A Robot Picker That Picks Trash And Store Into It's Trash Bin Thats In It's Stomach And To Dump The Trash Into The Garbage Truck Im Gonna Call That The Picker Uper 2.0 .Then Another Device Thats Gonna Be All Over The World Its A Air Conditoner That Gets Air Thats Pulluted Air And Turns It Into Fresh Air Im Gonna Call That The Air Fresherner 3,000

  • Which of above inventions might make the biggest difference to the world?
    **I think that what makes a big difference in the world is (Smog Free Tower because of the amount of pollution in the air produced, as it works to absorb the pollution from the smoke of factories and cars, which leads to an increase in the rate of diseases, so we need this device for air technology 2-Think of a new invention, give it a name and let us know how it would help to save the world in the present time. I think that the biggest problem we suffer from is the water pollution resulting from pouring waste and dirt and killing the fish in the sea. In our country and used in the fields of life and the name of this device [water purifier]

  • These days, I think that one of the biggest problems facing humanity at the present time is air pollution as a result of factories and the spread of polluted means of transportation, which leads to serious diseases, including heart problems, which are caused by inhaling harmful and polluted air from factories for a long time. Harmful air pollutants can be mixed, such as Carbon monoxide and nitrogen dioxide in the bloodstream for humans or even animals, I think that Smog Free Tower is the most appropriate solution to this problem

    1. What is a smog-free tower? How would it work?

  • Seed Drones is the invention that can make the biggest difference in the world economically because it can plant 40,000 trees a day because it is more than a person can do. An idea invention is a machine that can clean up land and water polluted areas in the world. I would call it the double cleaner because it can clean both land and water polluted areas. It can also ask people to help with the robot and they can share the idea with other people.

  • My invention would be a small, round and mini like a pebble water bottle with its cover as a edible transparent hard jelly that can bite right through.They can be different colours, like red, blue, pink and more. They can be made at home because it’s fun to make and doesn’t need to be brought in shops. This is also one way to give a treat for little kids if they have done something good. These homemade water bottles can be adjusted to any size and any shape you like ( the good thing is it doesn’t need to be water inside it!) .When you bite into it, it feels like your eating a mochi but the water comes out straight away. But once you bite into it, you have to drink it all at once!
    I hope this invention would be actually made in the future to stop people from using plastic ones.🍡⚗️👩🏻‍🔬

    1. I think this is a great idea, though it would be good to avoid making them with sugar.

  • Which of the above inventions would make the biggest difference in the world? why? I think that drones are among the best of these inventions. I know that each of them has importance and benefits, but this eliminates the occurrence of famines because it plants large areas, and from it may reduce the fatigue of farmers, save time for them, occupy large areas in agriculture and eliminate famines, and thus raise the economy of the country

  • I think that the one at the top 'seed drones' would be the most helpful as it can plant 40,000 trees a day; trees can produce oxygen to help us breathe in our world. without trees we would have less oxygen less fruit and no paper.
    trees are also key to some animals survival as trees are natural habitats for many animals such as bids, koalas and sloths. this will also help after wild fires to regrow natural areas.

  • I think the Seed Drone is a very helpful invention, and I'm sure others will agree. If we load the drone up with tree seeds from the Amazon Rainforest, we can regrow and rewild the rainforest area and extend the forest. It can grow into a perfect way to absorb Carbon Dioxide and help battle climate change.

  • The tower is of course wonderful, but seems to plant a plastic trees for 'decoration' instead of real plants for curbing pollutants. The tower can only arrest the particles suspended in the atmosphere, but can not give out fresh oxygen and absorb carbon dioxide from air. So, I think along with mounting such towers, plantation should be encouraged more and more. Plants and trees are more than this tower - and ofcourse are the real decoration.
    Hence, relating to my above discussion, I would say that the drone is more advantageous to mount the real decorative, cooling and pollutants arresting 'towers'.
    The sea bin is good idea but it will be more fruitful if the government and people are trained mentally not to make their sea water dirty.

  • Before being creative we have to shun double standards we follow. If cigarette is injurious to health, why its manufacturing is going on ? If plastic is hazardous for health, why pots of plastics, shopping bags are being made? If carbon fuel is emitting smoke and poisonous gases, why vehicle to use carbon fuel is made? Biggest creativity will be stopping anti environmental items manufacturing.
    Then we can move to he indispensable pollutants removing with true heart. Yes grow as many trees as you can. The drone is very useful for this purpose. Moreover, grow fruity trees, because pollination process will automatically work as invisible drone by spreading seeds of the plant by birds and even by human beings.
    Give awareness to the people for not pollute environment. Some times I could not find a bin to dispose of used bottle when I am out at a public point. Erect more and more bins along with awareness giving.
    Plants are taken as lungs of air. The tower is good option along with number of trees.

  • I think the idea of seed drones is a good idea and it will help to reduce climate change if implemented on a large scale although I am not sure what the drone uses as an energy source. Does it rely on solar, hydro, or wind energy and can it be made readily available and affordable for people in countries? I am also curious as to whether this invention can be used to solve the problem of farming in some countries where because of insecurity, people are afraid to go to their farms and which is reducing the food supply and causing hunger.

  • I feel the smog free tower would make the biggest difference. It purifies the air so people can breathe in fresh air. it would reduce the occurrence off respiratory diseases. On an average, about 10,000 people die of respiratory diseases everyday. With the use of the smog free tower, the mortality rate would be drastically reduced.

  • i prefer the seed drones because it can plant more than a thousand trees. It promotes afforestation in the world. When lumberjacks cut down trees without planting them back it leads to erosion, reduction of soil nutrients and flooding. It will create a lot of disasters that will affect both people, animals and crops. The seed drone will be a faster and easier way to be able to grow back the fresh green trees in our environment. the trees they grow will provide more oxygen, natural medicines instead if the chemical drugs we take and so many others. These trees are very essential to us in our everyday lives.

  • I like smog free tower because i live in Lahore, Pakistan and it's one of the most affected city by smog. I hope the local government installs these towers in Lahore so we don't have to fear going outside during smoggy season as it's very bad for health.

  • First, each of the three inventions is good and has a lot of importance, and we definitely need them in our lives because they contribute to solving a problem that has several risks to society. The first invention, which is the seed-planting plane, is my opinion and I say that this plane is a great deal, and this invention is impressive and successful, and the second most important invention because it relieved us of the burden Large and in the presence of these wastes in the water can cause serious diseases to humans and animals and by drinking poisoned water full of waste and this causes serious diseases and therefore it is a very good invention and the third and most important invention that rids people of the problem of pollution that hinders the breathing process and this pollution can cause a change in The climate of the country and therefore causes problems in all aspects of life. Therefore, I am proud of those inventions that were made with impressive hands. There is an invention that I have to solve the problem of waste sorting. We can put large baskets in every street, and each basket is for one material such as plastic, iron or bags, and it can be recycled and this solves a problem in My country

  • Personally, I think the smog free tower would be of better help to the world than all the other devices combined. One of the popularly known state for high pollution, is Delhi in India. Around 30,000 people die just because of the excessive pollution present in the air. Because the schools have been closed due to high level pollution, students face setbacks in education. Many people stay inside their homes so that they don’t get exposed to the polluted air which will cause them to get lung cancer and many other chronic heart diseases. Many such reasons contribute to why pollution adversely affects the mundane life of people in Delhi.

    Introducing new technologies like the smog tower would help Delhi to overcome most of these complications if not all of them.

    One of the most prominent geographical issues in my city Chennai, India, is immoderate flooding. Even with light drizzles here and there, the roads turn into puddles of water. One main reason is due to the poorly constructed roads here and secondly no way the water could move around. The rainwater gets stagnant, causing congestion in the movement of vehicles.
    For this my suggestion would be to permeable pavement and sidewalks.
    Another issue many sub-urbs face is flooding inside homes. Waterproof buildings, raising the electrical outlets are some ways to arrest it. And also, the green roofing would absorb the rainwater and help to mitigate flood.

    1. @charming_weaver I had no idea that there are so many people who die in India everyday, this is so sad! It must be really hard for students to learn when they can't go to school. I feel really lucky that I can still go to school in my country. We have pollution in Bucharest but it is nowhere near as bad as how it sounds for your citizens in Delhi.

      What a great idea to have a smog tower to help Delhi with this problem. These towers could also be a great problem solving for climate change. I think every city with bad pollution should use one of these!

      I also didn't know about the floods in India, this sounds awful. We also have poorly constructed roads here in our city but it is a different problem. Cars are always being damaged when they drive and also people can fall down the holes in the road which is very dangerous. Whats worse in our villages we only have dirt roads and people cant even drive on those when it rains or walk on them! However, again the situation in your country sounds even worse. I really hope that this can be problem solved for you! I have just researched 'permeable pavement' that you mentioned because I did not know much about it. I think its a great idea. I really pray that our countries will one day solve these issues for our people.

      1. Thank you for agreeing with my comment and also giving such a beautiful reply.

        1. you're welcome I hope we can all spread kindness together

    2. Personally, I did not know about the suffering of other countries, such as your city, Delhi, in India, and about the suffering of students there and their deprivation of education. For me as a student, this is a terrible thing, and I hope that it will never happen in all countries. Also, I did not know about the number of people who die due to pollution. And I agree with you about using fog towers to solve this problem, but we cannot rely on technology to solve this problem caused by humans themselves. And they are ignorant that the consequence of what they do causes death to others. Therefore, we must cooperate and prevent pollution from occurring, by preserving the cleanliness of the environment, and thus we will be able to overcome the problem of pollution in the world.

      1. absolutely agree with your point. Together when the youngsters come together for a cause, big things can happen.

  • There is a big problem in my area that there are plastic bottles, shopping bags and other non-biodegradable products thrown on the streets and in urban area that is a very serious cause of pollution. I will invent a car that will run by the solar energy and will suck the plastic bottles and shopping bags in it. The car will crush and take it to the factory where these products will be recycled.

  • we know that the trees are big sources of oxygen and they also contributes in the decreasing of global warming. Unfortunately, these trees are being destroyed by the humans at a very large amount. I will invent small drones that will run by the solar energy of the sun and will strictly look to these trees.in any case of cutting the tree, the drone will immediately inform the head office that will do action accordingly.

  • The seed drone is amazing! I love how it plants 40,000 seeds a day we need loads of them! The SeaBin is fantastic as well! there is loads of rubbish in the sea so its great that we can collect all the rubbish! the Smog Free Tower is amazing as well! I know I say all of them are fantastic/ amazing but they just really are!

    1. I agree because it gives lots of homes to animals

  • I love the seed done because there are so much people cutting down trees and I always wanted to help.:]

  • I love our world and I and I want to keep it like this so we need to save it

  • So far I have learnt a lot in global conversation. I have been able to have the discussion on things that could be done to stop climate change and the effect it has on our dear planet Earth! I have been able to have this discussion with my parents and other learned individuals in my community and we all agreed that seed drones would be the best idea to stop climate change and its effects.
    I say so because, seed drones can plant at least 40,000 trees in a day than what one person can do if given the same amount of time as the drone to cover. It is no news to us that plants play an important role in the ecosystem. More trees simply means lesser carbon monoxide in the atmosphere and more oxygen and this will support life on earth. In this regard, government should have policies and laws that speak against deforestation and support afforestation; that is, there should be a particular number of years before trees can be cut down and one cut down tree be replaced with two new trees.

  • In my opinion all 3 devices are very important and play a vital role in the environment. None of these three devices is more important over the other. They all play a role in eliminating the different forms of pollution in water and air.
    The seed drones aim at planting trees which will in turn help to eliminate or trap carbon in the atmosphere as this plants will use carbon for their metabolic activities there by eliminating the issue of air pollution. The sea bins will float over the surface of water and trap all wastes that will cause water pollution and so, in this case the issue of water pollution will be tackled if sea bins will be used. Lastly, the fumes or gases that will be released into the atmosphere by the seed drones and sea bins will be trapped by the smog free tower, making all three devices very important.

  • Sunlight drovers: A little robot that drives around: Forests,deserts,oceans,beaches and snowy lands.
    It has a medium sized solar panel that powers it. And it purifies air.

  • my invention is called climate helper, its an invention that prevents climate change and help animals by giving them shelter and food it also gives people free heating and shelter without hurting the planet.

  • my invention is called team sea it can clear the sea and clean the wasted material's that is left.

  • machines that are robots circling the earth making power witch lights and heats the whole worlds houses without hurting animals

  • I think the Smog free tower will make the biggest difference to the world. I say this because this Smog free tower is capable of eliminating large amounts of toxic carbon compounds that are in the atmosphere. This invention is a giant vacuum cleaner tower that removes smog or chunks of gases in the air and turn them into tiny or fine particles therefore making the air save without traces of carbon monoxide or other toxic compounds of carbon in the atmosphere.
    My idea for an invention for saving our world is to build machines that will be able to regulate and discard wastes properly in the environment. I will call this machine a recycle bot.

  • The eco bot will go every weekend round our estate and pick up the rubbish that is left on the floor and will tell us to get off the tv to tell us to save electricity and help us with the climate and maybe help us.

  • Nearly 2 million trees are being cut in a day. To reduce deforestation, my plan is to use e-books instead of papers. In school e-books, it should not have wifi or internet because it becomes like a cell phone. I think it would help us to reduce the use of papers and reduce deforestation.

  • I choose the smog free tower because a lot people fall sick with different illnesses like cancer, heart problems, kidney diseases, stroke and other pulmonary diseases. So the smog free towers will absorb toxic gases in the atmosphere that will help prevent human beings from suffering from all this illnesses. When human beings are healthy the economy would progress positively.
    My invention would be the cleaner 4000 which is a machine that works like a vacuum cleaner but it uses solar energy to work instead of electrical energy. This machine is capable of cleaning 4000 plastic bottles and polyethene bags in less than an hour. Even if the plastic bottles and polyethene bags are buried deep down in the soil it has the capacity to suck it out from the soil.

  • We only have one planet we can save it . But there are to many bad things happening, there is a war in Ukraine, there are floods and forest fires happening everywhere. We are a very lucky country. There is also the cost of living crisis that is affecting most people.

  • The seabin invention will make the biggest difference to the world. In my opinion, the SeaBin is a very good invention and should be put into usage in developing countries like Nigeria and developed countries like the United states. Take for instance in Nigeria flood carried alot of refuse which was later dumped into the sea by the help of the water current. If we had sea bins installed in big and small water bodies it (The sea bin) would have helped to keep the water clean even after floods. As we all know that clean water is a necessity for human survival. I say this because most people that live in riverine areas use the water they get from streams, rivers or lakes to cook or do their laundry. This is as a result of water scarcity in these areas and they have no or little access to good water supply. The sea bin would help clean all dirt in the water and make it clean and healthy for human consumption.

  • I choose the sea bin. Plastics do not decay instead they tend to shorten the level and amount of oxygen needed for the functionality of the aquatic life if dumped in water. We need the sea bin to help clean the water for our sea creatures.
    If given the opportunity to save our planet I will invent a machine. The name of my invention is will be a 'recycling speed' this machine will look like a car. It will have a waste collector which will be at the roof of the car. The roof will also have an opening where trash can pass through to the different compartments of plastic, food, fruits and vegetables, paper etc. This invention will sort will be taken for recycling.

  • I like all three inventions because I feel that each one of them has a benefit fit and an importance so:

    THE SEED DRONE: i see that it has a really nice job of planting a huge amount of trees and trees is from the most important elements of saving the climate change disaster because it produces oxygen for humans and the rest of the living organisms and sometimes we get fresh food from trees and plants and I see they this is an amazing benefit .

    THE SEA BIN: it’s a great invention because it removes any garbage from the sea and and the garbage that people throw in the sea is from the big reasons of the bad climate change, so I think that it’s really important for us especially this current time.

    THE SMOG FREE TOWER:smoke is the first and the biggest reasons of the climate change because it made the ozone layer get bigger so this invention will make the atmosphere free of any pollution so the best thing to do is to put at least three of the smog towers in each city in every country all over the world.

  • I believe the Smog Tower would positively affect the planet more I say this because unlike the other inventions, the Smog Tower can do its job, which is to reduce pollution on a mass scale, and due to research, I found out how it is designed to process 1,000 cubic meters of air per second. This technology would be of immense help to countries like Pakistan with Lahore being the most affected which produces 66.8ug/m3 of smog and this kills over 128,000 people annually due to pollution-related illnesses.
    The invention I thought of will be used along with the smog tower while the smog towers reduce pollution meanwhile what I call the Ozone Layer Restoration Plant (OLRP), is simply called RESTOROZONE. The device restores what has already been damaged. It would study and learn to recreate the part of the Ozone layer that has been depleted and the ozone layer fully restored by the RESTOROZONE human beings and all living things will continue with their lives without any fear of global warming.

  • I think the sea bin is the best option. Because it makes people throw away there trash and plastic so it wouldn't be so much ocean pollution in the water so the animal's can have somewhere to live. And so the oceans won't be so polluted.

  • The three of the ideas are great .Our country's city Lahore is very polluted the smog tower is best invention for the areas like Lahore which is very polluted especially it

  • As we know that about 5-liters of water wastes when we flush in the toilet. I will invent a toilet that has a tap on it. Every time, after using the toilet, we wash our hands. The toilet will use the water by which we wash our hands for flushing.

  • The three of the inventions are great.somg tower is best invention for areas like Lahore a city of Pakistan which remains air polluted most of the time the due to vehiclular activities and industries pollution it will make the air clean.
    There should be an invention that would that will drop the water there where we are sucking it from because sea level is increasing day by day which is a cause of may natural disasters.
    We should also build solar panels on the water canals like Pakistan has the the worlds biggest irrigation system.in Pakistan also the sun is bright about 9 to 10 months through these solar panels we could make our village areas get electricity through these solar panels they would also run their tubwells or motors used for sucking water, on this electricity.through this the use of fossil fuels like diesel and petrol will reduce and less amount of CO2 will be produced for harming the environment through these solar panels there would be less evaporation and water will remain cool and pollution free

  • In my opinion the three inventions , each one of them is important , but drones will lead to solving two problems, the first is to reduce the problem of hunger, so it can be used throughout the countries that suffer from this crisis, and the second is if the green spaces increase, the air pollution will decrease. These solutions will not be holistic, but rather Relativity would be a very useful invention. The invention of solar energy adds cherry on cake in terms of inventions . It helps in generating electricity. It will be the best solution and it will not be harmful for the air . These invention can benefit the world .All these inventions is making us developed and is benefitting the world

  • I think that the SeaBins can help us to reduce the water pollution. As we know that about 71% of our Earth is only water and all the fish and plants in water are effected by the water pollution. Majority of the plants in seas are used in production of medicines. Oceans are polluted by plastic materials such as bottles and bags. These materials not only very slowly degrade, but after a long time these materials cause spread of microplastics which are very dangerous for marine life.

  • I think that the invention "a smog-free tower" is the best of those ideas because nothing is better than fresh air for man and his health.
    As for my invention, I call it "environmental turbulence", which works by converting polluted air into unpolluted air and converting polluted materials into cooking gas.

  • These three inventions are also good but i'm thinking about a device which will tell us how much water we have used in a day and what is average level of usage of water, we are litle bit care less about the water, we do not have enough fresh water left to drink. It can be a big crisis in future. We need to think about this topic.

  • My Country deals with critical air pollution, from the landfills not cleared to the huge loads of smoke coming from many vehicles, our air purity isn't as good as it should be. I personally believe that the Smog Free Tower would greatly improve the cleanliness of the air in our day to day environment.

    My creative Idea that would help with water pollution in Nigeria are coagulant dispensers. A coagulant is a compound used to help clear impurities in a substance (in this case, water). When these devices are dropped at specific water bodies, they can sense when the water is becoming unclean, by the rise in PH level of the water, after sensing the unclean water, the coagulant formula is dispensed into the water in a proportional amount to the dirt in the body of water. The coagulants do their job and soon, there is clean healthy water for everyone to use or consume.

    This device could prevent many diseases that our rampant in the Nigerian community like: Typhoid, Dysentery, Cholera and many more.

    Thank You!

  • In the above inventions, seed drone is very helpful to plant trees.Trees work as air cleaner as they take in carbon dioxide that is harmful for atmosphere more than its original concentration and in return give out oxygen which is beneficial for breathing of human beings . They also improve air quality and reduce soil erosion.
    Sea bin is also a beneficial invention that clears 3.9 kg trash per day and 1.4 ton per year. It makes marine life safe and easy and also reduces pollution.
    Smog free towers help us to breath in clean air.It takes air in from the top and filter it. After filtration air is pushed out from 40 large fans present in bottom of tower.
    In present age ,every country is facing problem of pollution. Such as land, air and water pollution. These three devices are not expensive.So I shall prefer these all things.In my country Pakistan, there is about 8 million hectare land for cultivation so we should use seed drone for plantation of trees in the specific area .Seabin should used on ports to clean sea water. Smog free tower should be used in almost all cities.That is why I like all of above inventions.

  • Seed drones, The sea bin, and smog free tower they are all important but the most important in my opinion is Seed drones.
    Because if we plant all this amount of trees it will take most of the carbon dioxide in the air so first we will breath clean and fresh air second we will stop the climate change which is a big problem these days

  • I would make a device that takes pollution in the air and turns it into clean air like how water can be dirty be it can be cleaned and made into drinking water.

  • our planet is a brilliant example for what im about to say! Our planet is being distroyed by floods,fires and forest fires. I have alsoseen vidioes of people setting there rubbish on FIRE its horred I love our planet. I would also like to talk about something that makes me feel sad. I hate to breake it to you but theres a war in ukraine and its all russias fault! there one country stannding aigainst around fifty countryes. I would like to talk about our ocean animals. So as im tring to save our planet it all starts with people TO STOP LITTERING! I absolutly hate PLASTIC its like my biggest knightmare paper is not as bad becauseit disapears. But poor dolphins swallow it or get stuckin it and litter is horror id like to live on a planet that has fresh green grass,no DEFORESTATION and that doesn't kill animals. Last thing is deforestation now I can give you 2 reasons why this is bad.one its letting out carbondioxide and thats so silly we can die by destroying the trees.Two trees arent just there to look pretty there there to let out oxegen to make us stay alive. THANK YOU FOR READING THIS AND I'M SO SORRY IF THIS HAS TACKEN YOU SO LONG

  • The Printing Press. Gutenberg's first printing press. Prior to the rise of the Internet, no innovation did more for the spread and democratization of knowledge than Johannes Gutenberg's printing press.It can be argued that fire was discovered rather than invented. Certainly, early humans observed incidents of fire, but it wasn't until they figured out how to control it and produce it themselves that humans could really make use of everything this new tool had to offer.

  • Due to the high water shortage in my country as a result of bad use and waste of water, I will invent a water shower that monitors the amount of water we use or need

  • Personally,I think that the drones could be of much more help than the other two.Trees does the job of smog free tower as it can provide cleaner air for the people to breath.Apart from this,trees prevents soil erosion,helps in holding huge amount of water and prevents water scarcity too.It also provides people with food.Thus,this idea helps us in different dimensions.
    India has just 4% of the global freshwater resources but 18% of the world’s population.A lot of water let out by the industries are not only getting wasted but also leads to water pollution.Surface water is extremely susceptible to pollution stemming from human activities, such as the expansion of urban and suburban areas, industries, cities, and agriculture. In fact, sources of surface water have become the most common discharge sites for wastewater, which may contain microorganisms, pharmaceutical waste, heavy metals, and harmful pollutants.So I would suggest the use of nano tech to treat these waste water.Nanofiltration membranes, photocatalysis, plasma discharge, and nano-adsorbents, in wastewater treatment, as well as the application of nano-sensors for monitoring surface water quality could be of greater help.

  • I like all the above because these can reduce environmental pollution and increases environmental protection. The most I like is "THE SEA BIN" because nowadays we can see lots of Garbages is thrown into the sea . Because of these Garbages the marine animals life are in danger . The plastic that is thrown in sea is non renewable.Most of chemicals from the factories are mixing with the river and then river is mixing with sea. Chemicals is mixing with sea and the Marine animals are living in that so the poison may get into its body , then think about us, We like sea foods then think about our health?? So I think this should be used in all countries .

  • I am a Pakistani ,and in my point of view if we can use the "seed drones" then we can save our planet more effectively than that of other two ways (i.e.smog free tower and the seabin) because I think if there are more trees on our planet,then the air in our environment become more and more pollution free.That is why I think that the seed drones are the best means to save our planet.

  • I live in Pakistan.It is an agricultural country.So I would like seed drone the most as it helps to plant trees more than one man per day.Trees clean air by absorbing CO2 from air and release oxygen which is essential for breathing of human. So I prefer seed drone the most.

  • According to me sea bin would be the best innovation,because it helps our nation by removing of the waste and hazardous things and make the water available for the usage.
    And the invention that I have as idea is that saving the rain water that is being running on the roads and inside the houses of people at the time of flood and other natural calamities.These water are being mixed up seas at last
    My idea is that connecting all over the world through pipelines and using of this water from the places of excess to the place of shortage.
    By this we would save the water all over the world and at the same time everyone will get benefitted.
    Natural resources are the gifts that are provided by the Earth to all of us
    Let's stay together and save the planet,and thank the planet for all the resources that it has shared to us by using it wisely!!!

  • How can we save the world ?
    We are the first generation to notice that we are actually destroying the world ! and we could be the last to do anything to save it
    there are alot of things we can do to the save the planet such as
    Reducing, reuse and recycling
    volunteer for clean ups in your community
    education which is the most important
    conserve water
    choose sustainable
    shop wisely
    plant a tree
    We have to save the earth and its a must so the next generation can live in a safe environment, Theres also many ways to save Earth such as saving trees , natural vegetation, water , natural resources , electricity, etc..
    We all should follow all the possible measures to control the environmental pollution and global warming.

  • These three inventions are useful, and the invention of airplanes I think is cool, just knowing that they grow up to 40,000 trees per day is really amazing, and therefore by increasing the trees will reduce the pollution of the environment, and this is also a solution to another problem, but there are negatives It's a drone that reduces job opportunities.
    For me, I encourage the use of renewable energy sources, such as solar energies, because they are considered environmentally friendly and do not produce harmful gases, because these gases have a great impact on the climate, and evidence of this in South Korea is that the climate is gloomy in most seasons as a result of the harmful gases that are produced from Factories emitted from China. Let's go back to the point of planting trees, as it is one of the most important "natural climatic solutions."
    In maintaining soil fertilization and fertilization, there are many methods for preserving lands, but we see that the rate of deforestation is about “two billion hectares.” This is very harmful to the environment because trees are the “best carbon sequestration technology.”
    In the end, I want to reduce the use of electronic inventions, because they require a large financial cost, and with the passage of time their work will weaken, since they are electronic devices and therefore will not be sustainable. I prefer to focus on natural solutions and try to benefit from some things such as desalinating ocean and sea water instead of groundwater and many solutions other.

  • I think all the inventions are incredible and will help save our planet.

    1. The seed drones are great as they would help us replant trees. Also, whilst other trees are being chopped down for resources; tree-planting drones would be able to repopulate the world with loads and loads of trees and give us more oxygen and food.

    2. The sea bins are great as they would help us collect rubbish from the ocean. Animals wouldn't have to suffer by getting caught in plastic or eating it for it to get stuck in their bodies. If there was no plastic to harm them. For example, there was a picture of a turtle who got stuck in a six-ring plastic pack and 20 years later it got stuck in its shell and couldn't breathe properly because of the plastic. But at the same time if it is just a floating bin animals could still get stuck inside it and think it's food or even get trapped in it and float into the bin. But then, if humans didn't use as much plastic there wouldn't be any or that much in the ocean.

    3. The smog free tower is great as it would help us to clean our air. The smog free tower would also help our air become way purer as we have a lot of factories that cause a lot of pollution at the moment that the smog free towers could clean up. Even though it would help clean the air, you would have to get a lot of them to clean up all the pollution.

    I think that the tree planter is the best because in my area people keep cutting down the trees without replanting them. Also in my school, trees were cut down in our back playground which haven't been replanted either, so for me, the tree-planting drones would be the best.

    What I would invent would be a system whereby once a tree is cut down, a notification (through a GIS tracker)would be sent to the tree planting drone to replace the tree. Hence, all trees that are cut down will automatically be replanted. I would make the system such that it will identify all areas that need trees or greenery; a small tower that would have a camera attached to it so that the operator of the drone could see all the trees in the area and when a tree chopped the operator would send a signal through the nearest tower to the nearest done and the drone would plant a new tree in place of the one that was chopped down.

  • All of these inventions help keep our environment clean. The invention of seed drones increases the number of trees that provide our environment with oxygen and reduces carbon dioxide in the air, which helps reduce air pollution. The seaBin invention purifies water from plastic that decomposes after hundreds of years, causing pollution, so it must be taken out of the water in order to preserve it from its dangers. The invention of the smog Free Tower helps in purifying the air and making people breathe clean and pure air. This is a wonderful thing to think about and help find solutions to save our environment.

  • If we look at our surroundings, we can notice that deforestation is increasing day by day at a very high rate, and in my opinion, seed drones can help prevent this awful situation. Seed drones are specialized to plant at least 40,000 trees a day, and it is not possible for a human being to do so. This will increase the rate of afforestation, which will further lead to a healthy environment.

    Whenever I go for a walk outside, I always notice plastic bottles, plastic bags, etc. lying on the street. To solve this issue, I want to build a vending machine named "Revend" that'll allow us to buy recycled goods.

  • I really like the idea of the smog free tower and the seed drones because both of them do such a useful thing in which the smog free tower absorb all waste gases and that's very good and also we people could also do the same thing by developing new sources of energy and and creat electric cars that doesn't hurt the environment the seed drones is also very useful because it can plant a lot of trees and this is a very good idea because like this there will be more oxygen than carbon dioxide because trees absorb from us carbon dioxide and give us in return oxygen so this is very helpful because if we didn't plant trees there will be more carbon dioxide than oxygen and that will cause global warming environmental issue and that causes that a lot of animals are endangered like polar bears their habitat is to live in cold areas and due to of global warming the are endangered so planting trees is very important and we should plant a lot before it's too late

  • I would love to create a giant trash picker and it is maid from the things it picks.It has a sticky form that attracts every thing it lay on. It will be a very small device that grows up with. If you feel that it is big enough you can get rid of the trash and regrow again.And I will name it (MY GROWING TRASH).

  • Its good to recycle and plant trees because it can find animals a new home and the animals that live in the ocean don't have to suffer to death. It is also good to breath clean air because if we don't people asma have a close chance to death.

  • My community suffers from a lot of air and land pollution and I recently learnt of how artificially made perfumes cause huge problems in contaminating the air so why not go natural with plant based body mists that does very little or no depletion to the ozone and focus more on robotic trash cans that reduces the cumbersome task of heavy duty trucks handling waste that give of harmful fumes.

  • The invention that would make a difference is the Smog Free Tower I chose because it gives an immediate result that purifies the air directly and not like seed drones. The tree should grow to purify the air and there is a possibility that it will not grow, but it is important in the long run.

    I personally suffer from the problem of bright lights at night, especially at bedtime, and since my brothers are young, they are afraid of the dark and light up the lights. This is my personal problem, but if we think carefully, it is an environmental problem as it disturbs the animals' sense of night and day, which reflects the biological cycle and causes In exhausting many insects that are often from pollinating crops in the region, thus the lack of agricultural crop and on the human level caused it (dwarf) or lack of secretion of growth hormone. Its light corresponds to the light that animals can tolerate. I want to name my satellite (the Moon of Life). I chose this name because it will preserve the natural life of animals, plants and humans.

    1. Great job sharing an experience of your own and linking it to real world example of light pollution!

  • Hi I think the drone is the best idea because planting seeds every day and it will help provide more animals homes

  • I think a great new invention would be a solar powered car so it would have about six panels on it and when you drive it can make electricity from the panels to power the car

  • In our country, sewage is abundant, and we need an idea to reduce this. Everyone believes that there is no solution except by inventing a device that draws sewage, and they do not see that there is a solution in our beautiful nature. The pomegranate tree is a tree that has the ability to absorb more sewage than other trees. If we plant pomegranate trees on a larger scale, we may be able to reduce this problem.

  • I think that growing trees would help because the greener the Earth is , the healthier it would be . School's in the world can have gardening club would help the world to be a greener place . When all the world leaders meet up and get on a private jet or a vehicle , is unhealthy for the world so I think having a meeting online would be healthier for the world .

  • Keeping in mind my countries floods I would prefer seed drones as it would be used 2 in one. Food shortage of pakistan can b made up only by growing more nd more plants... although we ve to wait till growth of those plants yet we would try to manage other areas crops wisely to provide food for flood affected . It's a ray of hope nd its capacity to grow 40000perday is amazing .. we can also contribute to contro world hunger too . One more thing it would beautfy the flood areas. I would use my creativity in making organic cosmetics like lip glosses, nail polish nd eye shades . In this way ,skin issues would b reduced . This is what for what I can benefit from seed drones .

  • Large meat-eating animals are rare in nature because their existence requires a lot of prey. For every harmful animal in the Serengeti, there are more than 100 prey. Whenever we go out to choose a piece of meat, we also need spontaneously to vast areas. The planet cannot accommodate billions of meat-eaters because there are no spaces Sufficient, but if we persist in following a diet that is mostly high in plants, we will need half the area that we need now, and because we will be interested in cultivating plants, then we will increase the productivity of this land, so I will choose drones

  • I think the smog tower is a good idea because we need to breathe in clearer and cleaner air. It is a really good machine to use during cop27. You should make more around the world.

  • smoke free tower is really really an amazing idea. it is really a good source of eliminating pollution from atmosphere but i was thinking a thing too
    It is almost similar to smoke tower but it would be an oxygen supply tower. I was thinking that what if we could build an oxygen supplying tower because due to over population the trees are being cu and in future there is a fear of shortage of oxygen so i think that if we could build a oxygen free tower it would be good for incoming generations

  • The best way that we can save the planet and the only people that can make this possible is the citizen. If every body is very cooperative their wont be any issue. For example the government can play a role in enlightining the citizenson proper disposal of waste, and the citizen can also ply their part by listening to the world of the government and carrying it out by doing so we can solve the problem of dirty environment which causes air pollution and it is not healthy the society.

  • The seed drone is the best innovation for me because it can plant up to 40,000 trees a day. If this amount of trees are planted everyday, at the end of a month or year we will have solved some world problems. Some examples of these problems are food crisis, climate change, we would find some cure to some diseases(herbal drugs), restore animal habitat and also reduce the rate at which species are getting extinct. I do not have any innovation in mind but I would love to support the seed drone. In addition, it will also make farming activities less stressful and the yield more.

  • One thing in common about all these inventions is the fact that at the end of the day it helps the planet, at this point in time we need every help that the earth can get, not just help to the humans but help to each living creature. We also have to look at the overhead cost of some of these things, which one is cheaper and can be used in rural places too ? That should be the question.

  • I see that the three inventions, each of which is no less important than the other, but drones will lead to the solution of two problems, the first is to reduce the problem of hunger, so that it can be used in all parts of the country that suffers from this crisis, and the second if green spaces increase, it will decrease Air pollution. These solutions will not be exhaustive, but relativism will be a very useful invention. For me, the area where I live is a conflict zone. There is no stability or security on all sides. There is a problem we have been suffering from for 16 years without electricity. I see the use of solar or sea energy to generate electricity. It will be the best solution and will not harm the air and the air, the invention that can benefit the world. I see that it starts from peace, as peace will lead to an ordinary generation capable of innovation and excellence, but in the shadow of wars there will be no creativity

    1. You make an excellent point @reflective_journalist – peace and security are vital preconditions to enable innovation and progress.

  • To me all of them are great but i think that the seed drone can make a bigger difference in the world, because they can plant up to 40,000 trees everyday which can help the societies in things like respiration. The trees can even serve as habitat for some animals and some human beings.

  • my moto is reuse refuse recycle. everything can be recycled into another nothing really goes to waste. even dead bodies can be used as organic matter for plants. the question is what can something be recycled to. in my community we face pollution of faeces and waste. so I feel taht this waste can be used as organic matter for plants.

  • Seed drones are a great idea since it saves loads of time so farmers won’t be tired but it may cause lots of money wasted and it seems a bit lazy but it seems good :)

  • Ohh an invention to save water , that’s amazing !
    Water pollution is now a very big problem on many levels . First , sea animal are being harm because of plastic rubbish thrown in the water . Also it has deadly effects on human , and according to the UN, every year, approximately 297,000 children under five die from diseases linked to poor sanitation and hygiene, or unsafe drinking water, this search was done in 22 November 2020 , and this pollution is getting worse and worse .
    An invention I could suggest is a device that can take out oil from water as fuel dropped by ships and others . This invention plays a role in saving water and animals .
    Do you think that this 71% of our plant is enough ?

  • I think seed drones are a good idea to save the planet because we need lots more trees as people are cutting down trees. I think we should plant more trees in hotter countries. Also seed drones can help cop27. that has really inspired me.

    1. I agree because... if you have less trees then you have more co2 and it will harm the environment and we don't have another planet

  • I think the smog tower is a great idea because pollution is really bad for people with asthma and i think there should be more all around the world

  • I name my invention the ECO house. so everything in the house is ECO it is made of ECO materials and the light it
    isn't made from using electricity. The gas is not using carbon dioxide and using coal i just think the ECO house is very high in ECO carbon footprint.

    1. Your idea is beautiful, but I think that if it was implemented, i.e. coal was used, it will become a very big pressure on coal. I think that the basis for using coal in the manufacture of iron and steel will be reduced, and people depend on coal in many inventions, and this is not good

  • Smog free tower really seems a great invention. It looks like having exactly what we need for solving this problem. People also seem to like it. But if it is such a briliant invention, then why don't we build more buildings like it? Is it because of no money, or there are still some things we need to fix at this building? I am very curious, since I don t understand why to stop at one building. Only one smog free tower won t make such a big difrence, but hundreds or thousands smog free towers surely will.

  • I think the smog tower is a great idea because some people have athsma and pollution is extremely bad for them and some people can actualy get athsma as well. Also its good for the enviroment so i think there should be more all around the world and yes your right it really does look like a piece of art. It would be amazing if smog free towers were closer to roads as well so it could suck up all the pollution that comes from the cars and you wont have to breathe in all that smoke.

  • In my view,the seed drones might have a big difference on the world cause as they help reduce temperatures,reduce the amount of carbondioxide in the air through photosynthesis and release more oxygen into the air.They also increase the amount of rainfall received.In other words planting more trees can be a source new jobs for people forexample taking care of them,operating the drones,making seeds ready for planting rather than industrilization that creates jobs but also pollutes the air and water bodies through disposal of wastes

  • Due to the high water shortage in my country as a result of bad use and waste of water, I will invent a water shower that monitors the amount of water we use or need. When we use more than the amount we should, the shower lights up strongly in order to warn the person to get out of water when there is an excessive use of water. It also can minimize the size of water drops, as well. I'll call it the smart shower

  • The seed drone might make the biggest difference because if we are to use these drones, the rate of planting trees shall increase of which these trees first of all, they will absorb the bad air that's to say carbon monoxide which destroys the ozone layers hence to climate changes like global warming and planting trees shall prevent this. Still when we use these seed drones to plant trees together with crops(agroforestry) , we are increasing soil fertility meaning production of more food crops solving a problem of low food production. So using seed drones is a method that can be used not only to solve climate change due to pollution but also hunger due to low food production

  • Personally, I think the smog free tower would be of better help to the world than all the other devices combined. One of the popularly known state for high pollution, is Delhi in India. Around 30,000 people die just because of the excessive pollution present in the air. Because the schools have been closed due to high level pollution, students face setbacks in education. Many people stay inside their homes so that they don’t get exposed to the polluted air which will cause them to get lung cancer and many other chronic heart diseases. Many such reasons contribute to why pollution adversely affects the mundane life of people in Delhi.

    Introducing new technologies like the smog tower would help Delhi to overcome most of these complications if not all of them.

    One of the most prominent geographical issues in my city Chennai, India, is immoderate flooding. Even with light drizzles here and there, the roads turn into puddles of water. One main reason is due to the poorly constructed roads here and secondly no way the water could move around. The rainwater gets stagnant, causing congestion in the movement of vehicles.
    For this my suggestion would be to permeable pavement and sidewalks.
    Another issue many sub-urbs face is flooding inside homes. Waterproof buildings, raising the electrical outlets are some ways to arrest it. And also, the green roofing would absorb the rainwater and help to mitigate flood.
