The most dangerous thing to threaten polar bear habitats the freaking ice melting out from under them, which is totally NOT caused by global warming, you filthy hippie, is grizzly bears. Sick of being consigned to more southerly habitats, grizzly bears are arriving with troubling regularity in what scientists traditionally think of as polar bear habitat in Manitoba, Canada.
The bad news is that the two biggest species of bear in the world slugging it out with their very survival at stake is terribly, terribly sad, and promises to be just one more strike against the polar bears already dimming prospects for long term survival.
The good news? Dude, did you not see the part about “the two biggest species of bear in the world slugging it out with their very survival at stake?” This will be a super awesome animal fight, on par with shark versus crocodile, gorilla versus anaconda, and boxing kangaroo versus talkshow.
Place your bets on the future of all ursine-kind today and get prepared for the battle of the century. Round One, FIGHT!
