| #2 Between that bright ball in the sky, tectonics, and the occasional belches of mother earth [Krakatoa, Toba, Yellowstone, etc], man is indeed very insignificant in climate change. However, man has proven himself to be very adaptable since the last ice age, now occupying terrain and environments that stretch from the arctic circle to the equator, from high mountains to deserts, from lush broad savannah to isolated islands in the vast Pacific. Whether cognizant or not, man has practiced 'adapt or perish' long before Darwin's observation. The only environments we should be concerned with manipulating are those on other planets to avoid being stuck on only one when the next KT event strikes. |
