Polar bears in the southern Beaufort Sea may be turning to cannibalism because longer seasons without ice keep them from getting to their natural food, a new study by American and Canadian scientists has found.
The study reviewed three examples of polar bears preying on each other from January to April 2004 north of Alaska and western Canada, including the first-ever reported killing of a female in a den shortly after it gave birth.
Polar bears feed primarily on ringed seals and use sea ice for feeding, mating and giving birth.
Polar bears kill each other for population regulation, dominance, and reproductive advantage, the study said. Killing for food seems to be less common, said the study's principal author, Steven Amstrup of the U.S. Geological Survey Alaska Science Center.
"During 24 years of research on polar bears in the southern Beaufort Sea region of northern Alaska and 34 years in northwestern Canada, we have not seen other incidents of polar bears stalking, killing, and eating other polar bears," the scientists said.
Environmentalists contend shrinking polar ice due to global warming may lead to the disappearance of polar bears before the end of the century...
Soon it will be man against man, vying for land and food after most of the world is submerged underwater. I've already got reserervations at
Au humain. Zagats gives them for 18/20 for their prime cuts.

think about it, if you look at a U.S. map...the only real danger is to where all the dummy-crats congregate...califonia,new york,florida,louisiana,washington,etc..
no big loss. i think we'll manage somehow.
besides...i hear polar bear tastes just like spotted owl.
Oh Ogre, how ironic that you are calling Dems "dummy-crats" as your rudimentary knowledge of North American geography and recent US Voter patterns is clearly at sub-ignorant levels.
How is it that you expect Polar Bears to make it to California, Florida and Louisiana from the the Poles? Perhaps they can float all the way on an ice raft?
Additionally, Louisiana and Florida (Jeb country) went Republican in the 2004 Presidential election did they not?
listen up moron... i was talking (perhaps not clearly) about the oh so imminent flooding of the coastlines and whole populi of misguided voters being put out of my misery..
and about florida...even dummy-crats can grow a braincell once in a while..ever hear of Reagan democrats??
besides....EVERYONE knows tha polar bears are VERY good swimmers.
Ok, no more name calling. As a good natured liberal, I demand peace on this blog!
