Thank you. Finally someone more on my side. I think that after a while, the billions (is it up to a trillion now?) of humans that have passed through the earth will have made a huge effect on the environment. Problem is, how do we prevent ourselves from being destroyed. And even if we do make it for a few more billion years, black holes will suck up everything and we'll all be annhilated anyways. But that's a long-term problem, not to mention irrelevant to this thread.
