> I'm confused on why people actually care about global warming.

If you accept the premise that biodiversity on Earth is intrinsically valuable, then one ought to care about global warming.

> Also, to be honest who cares about all the other animals? The same people who complain about climate change killing the polar bears are the same people who eat other animals.

If someone eats, for example, farm-raised chicken, it does not logically follow that they ought not to care for the well-being and survival of other animals.
