If they aren't beneficial to humans, no. But most of them are in some fashion because the extinction of one species often throws the ecosystem out of balance where it resided. For example, if the north American cougar became extinct, it would cause a rise in deer populations, which may cause them to damage crops when they run out of grazing land. Of course this particular situation could be easily remedied by allowing more deer tags during hunting season, but my point is that it's important to prepare for the ecological changes that will occur if and when we remove a species. Ultimately though, the ecosystem is self stabilizing and does not require the existence of every species that currently exists.

They are endangered animals of course we save them. And how ignorant was the comment about obese people, There is a hobby for you shoot all the ignorants you come across oh wait that would mean that you have to shoot the ignorant who made the comment!!!

The human race is nothing but a horrendous disease that has spread like the plague over this planet. We multiply like crazy, and lose our minds when something invades our territories (like a squirrel in your back yard). I think we need to stop taking ourselves so damn seriously.
