Just as a note, I don't think it's fair to make that comparison you make in your edit. One thing is that we want to reduce risks with other species, to keep a "normal" balance, with "normal" meaning "what we've been seeing the last days we've been taking notes", and another what affects us personally. Are we willing to take some risks with overpopulation? Otherwise, are we willing to take some risks to prevent overpopulation? I think you can't compare the two situations like that. Personally, I don't know where to stand. I used to believe overpopulation was a big problem we needed to actively tackle. Then I started considering self-regulation theories and the issues with population control methods, and compare it to other global problems. I don't have a clear view anymore. Definitely worth discussing, definitely a very complex situation.
