COP events are not sustainable.They have wasted millions of pounds.There not inclusive for many people so they can share ther ideas{too many men}.There have been serious changes in weather and temperatures.There is to much talking but they are not taking action for our world.Also COP 27 this year has not been. COP leaders are polluting the Earth causing carbondioxide which is made up from lots of gasses then turns into global warming.In COP 27 people have to travel around the world to get to the events this causes air pollution which is not good,world leaders need to stop this by travelling by a boat,train,electric car {if possible}.
