Yet another stupid evolution 'debate'

[Immortal Goat]

Big Papa Goat, how can you possibly argue that humans have not had a completely negative, detrimental impact on this planet? I justify human morality by my belief that, even though we've fucked the world, we're already here, so we should prevent as much further damage as we can. We have evolved our sense of morality, and we can't go back from that, so we must deal with it.

EDIT: I hope I'm not in the "stupid" catagory, because I completely agree with Kahl here.
