GLOBAL WARMING IS GETTING PRETTY BAD

Study: Polar bears may turn to cannibalism

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.

The headline for the story is misleading. It should read "Polar Bears Are Turning to Cannibalism" because, as the article observes, this is happening right now. It's pretty simple. The bears need the ice in order to get across water to where their food is; without the ice, they're starving and eating each other, just as human beings would probably do under the same circumstances. Take this as a bad omen: man made global warming may turn us into man-eaters, eventually, when the weather patterns have changed so drastically that the economy is destroyed, taking food production and distribution with it. Pretty creepy. As if polar bears eating each other wasn't creepy enough.
