don't some scientist still say that we are still coming out of the last ice age, and that it is perfectly logical that the earth is getting warmer because of that?
personally, i think we humans give ourselves too much credit for being able to alter the earth. sure, some of the stuff we are doing as a species can't be good for good ol' mommy earth, but i don't think that, on the whole, we are doing too much bad, either.
like George Carlin (who is a very, extremely liberal person, btw) said in one of his comedy specials a while back (or something like it, anyways).
"to the earth, we are a minor infestation".
