Number 1 cause of destruction of env (not just talking about carbon emissions but pollution of water, deforestation the whole ball of wax) is over population. In poor countries with no or little population control you see blatant destruction of env. Forests are cut down for firewood, water is polluted by non existent sewerage treatment. Just think of Easter Island, except that because the land mass is larger it takes a longer time. I agree that advanced countries are responsible for a large % of global warming. But what would other forms of destruction of env?
