I have wondered this, myself. I think I’ve even written it somewhere here, or elsewhere. I do think that diversity will continue to crop up, as the environment changes. As to protecting species, I really think we only protecting a few, mostly large mammals, and that won’t make a significant difference in terms of evolutionary success. Hmmm. Will polar bears learn to survive without ice? I don’t think conservation is inherently wrong. I think that humans are doing what they think best to maintain a salutary environment for ourselves. We’ll stop conserving if it doesn’t make any difference, but I’d have to say that our efforts to clean up pollution have made a big difference in the quality of our lives. I don’t distinguish between human pressures and meteor strikes. It’s not like we’re the only animal that has grow too profligate and dramatically changed its environment. We’re a part of nature, as far as I’m concerned. The planet will survive, with or without us. Life forms will change with or without us. There is only one course of history, so what-ifs are useless. We do what we will, and to ask whether conservation efforts are inherently wrong will change little, I think. We will do what we are doing, regardless.
