Probably because extinctions aren't actually occurring at the rate they're being claimed to, that's why. Population collapse from large numbers down to much smaller numbers is one thing (and is probably what's really happening here), but outright extinction is something else. I've lost track now of the number of times some species has been declared "extinct", only to have it pop up again later. And IIRC, lately there have even been claims that a species can actually go extinct, only to have a closely related species then morph into that extinct species, almost like nature has a "reboot" button for when a species does go extinct.
