U.S. declares more than 20 species extinct after exhaustive searches
I am probably just a horrible person, but I just don’t care about the extinction of such specific species.  Often a member of one species is practically impossible to tell from a member of a different species save for where the individual was found.  I care a lot more if “crows” are endangered than if “efitz’ southeastern marble crested crow” is endangered. [ed: spelling]<p>Also, I suspect that such narrowly defined species go extinct rather frequently; it’s sad that human destruction of habitats contributed but as a species we Homo sapiens outcompeted them and made the world better (in someone’s point of view) for Homo sapiens, or we wouldn’t have been developing the land in the first place.<p>In policy setting I would strongly prefer that we look at things less granularity than the species, at least for small animals.
