I heard of a solution to the pollution, or at lest the beginning of it.
It is a known that humans been act according there own interests. The thing is human as individuals that act according to their owe interest on the grant scale may have negative influence on themselves and on other people.
For example in South America there are people who burn down forests because of there own interests. They, of course, do not do it for fun. They burn forests so they will have more room for agriculture. More room for growing food.
So the solution is that the UN will agree on international law that allows some quantity of CO2 pollution to all earth. That amount of CO2 will be decided by few international studies.
Every country on earth will be allowed to pollute according to the O2 emission. If in some country 20% of the O2 is emission then they have a license of 20% of the allowed amount of CO2 pollution. The country may sell some of hers license. then it will be the country's intrests to protect the forest.
this proposal alredy exist. but what i ask of you is how one can convince most of the world,
how to make them want (have interest -economical, political or emotional) to agree to this kind of low
