It would be difficult to argue with your points. Every human being on planet Earth should make a serious effort to reduce his/her ecological 'footprint'. We are wasteful, careless and arrogant.
That said, the accords mentioned here claim to reduce air polution (at least one part thereof) and eliminate Global Warming. They do neither, and may cost the US and Canada, if fully implemented, over 3 1/2 trillion dollars. They also makes us less competeiive with China, India and other powerful nations.
