I don’t think we ruin everything… We’re also the best around at improving things, certainly improving our environments.

I know it’s easy to be pessimistic about these things, but humans are evolutionary badasses. We’re capable of amazing things. I wouldn’t count us out just yet.

Besides we haven’t really ruined anything. We haven’t done any damage to the earth that won’t heal eventually. The earth has seen many heating and cooling cycles and plenty of mass extinctions before and it will again (with or without humans).
