Why does protecting the environment often require international legislation?

scientists must have confirmation from other countries that there are problems

what happens in one country is likely happening in other countries

global circulation patterns mean that chemicals released into air or water are the problem of all nations

no country will take blame without pointing the finger at other countries

too many countries are ruled by dictatorsWhy does protecting the environment often require international legislation?Heres the problem. Pollution that goes into the air in India does not stay in India, it goes global. Even if it did stay, pollution often has far reaching effects that cant take a long time to feel.



If we swallowed the pill, spent trillions, took the economic heat to drastically reduce our emissions, but other countries didn't, we really wouldn't benefit very much. It also gives countries unfair trade advantages, if their industry can freely pollute, they can make stuff cheaper and price cut other nation's goods.Why does protecting the environment often require international legislation?Your question is a little confusing, you seem to have answered it and then some. The fact is we don't live in individual national enviorments, we live on one big planet with one enviorment, therefore, if one country does something (pollution, trash dumping, etc.) it will undoubtedly effect another. On the same hand, if we don't coordinate with other countries then whatever efforts one country takes to stop doing something will just be negated by another country who keeps doing something.
