Abortion, Animal Rights, and Capital Punishment

Which leads back to the OP... what about people who are for animal rights, but don't have a problem with the world slowly (and rapidly) getting ruined for the rest of the planet due to humanity's actions?? Humans, for some rather illogical (although, understandable - psychologically speaking) reason seem to think that all other human life is important - more important than any other creatures (except in cases where a human has formed a bond with some animal). You don't actually see something like that anywhere else on the planet... unless an animal is related directly to another one, it really doesn't give a stuff what happens to it's neighbour... sure, this has had some good effects for humans (society), but I'd say it has it's down side as well....

Not quite. Many mammals can and do adopt young of other species.
I witnessed video of a wild rhino trying to help a trapped elephant young, despite its mother's nervousness and insistance to privacy.
Keeping pets is not unversal among humans, so we must consider individuals of other species when discussing such behavior.
