I'm always left scratching my head at some of these types of comments. Yes, you do lose something valuable when a species dies, but you also lose something valuable when almost anything dies be it one creature amongst trillions of its own kind, or one amongst only a dozen.
We belong here on this planet just as much as these condors do, if not more so. The reason we live and they die is because we're the more capable species. Nature is a mother. We live, they die.
This has been going on for untold millions of years and it's not going to stop until the world ends by some means. To try to save every last little animal in existence is just neurotic. If anything we're interfering by trying to preserve this species.
Now I agree there are very practical reasons for trying to manage wildlife and I can understand why it's worth the time to try to preserve species long enough to learn about them, but the hard fact of the matter is that if it's really that important, it shouldn't ever be trusted to the government.
Many people have been denied the simple right to build on or develop their own land because some biologist decides it's a habitat for some obscure critter because only a handful of them live there. Never mind there could be a huge concentration of them somewhere else.
Some people say "You need to get your priorities straight". Yet the penalty for drunk driving is usually less than the penalty for killing an endangered animal. Fines of over a hundred thousand dollars and long jail terms are quite possible for killing a certain animal by accident, whereas deliberately harming human beings often carries a light penalty.
Yes it would be nice to have enough specimens of each species which ever existed on earth in perpetuity for various purposes. But that's not practical, nor is it natural. We as humans are not aliens who have interfered in nature and disrupted its balance, we are a part of this planet, and this planet does rather incredible things, like discard entire species. And some day, there may be a species whose existence on earth means humans are next to go the way of the Dodo bird.
Rather, we should study these birds and see if there is a useful product we can obtain from them, be it a chemical reagent, foodstuff, or even perhaps their service as natural carrion eaters. Heck, put a colony of them in a preserve somewhere to insure they never completely disappear and that we can always learn from them. But do it on your own dime if you think it's so important, and stop making ridiculous demands like a ban of lead ammunition which infringes on the rights of other people.
