The question is...how much do we contribute...and what kind of lifestyle do you want?

ARE we really contributing to warming? I've seen the time lapse of glaciers receding, so it seems to be true that the planet is warming. But how much is our doing?

Second, do we want to live 1sr world? 2nd? Or 3rd?

Come to think about it...we'll be 3rd world within 30 years due to demographics anyway. So, the whole discussion is moot. Humans won't be creating much CO2 much longer as the world becomes 3rd world.
