To me, our impact on nature is directly limited to mankind's future. If we scorch the earth with nuclear warheads on 10/15/2011, we will not be able to survive, but the earth will and some type of life will.
I dont know why we dont spend more time and energy working on land use issues and the impact of cancer causing polutants from industry.
the real issues are being over looked because of an insane fixation on carbon dioxide.
