Polar bears have no natural predators, so, like pretty much every other wild apex predator, unless they drown, die from disease, are killed by a human hunter, or are killed by another polar bear, they usually die from starvation when they can no longer effectively hunt prey. Sad as it is to think about, there are no polar bear nursing homes, but that’s the natural order of things.
Yup. No Polarbama care available.

Not even chupacabres?
