Well, reader Elisheva just sent me a great link to a site that shows that actually, the polar bears of Hudson Bay and the Baffin Islands (where the 'starving' bear video was shot) actually have a different health problem to contend with, if any:
They are fat!
And some of them are positively obese!
(In polar bear terms, this is a good thing, because more fat helps to insulate them from the cold).
You can read more about them for yourself, and see more pictures HERE.
But it looks like even the polar bears are enjoying global warming.
