Arctic Polar Bears Eating Each Other

Polar bears are resorting to cannibalism according to a new report by the journal Arctic Institute of North America. Scientists believe this is because the Arctic sea ice is declining due to global warming.

Polar bear biologist Ian Stirling and photojournalist Jenny Ross (her photo is to the left) describe seeing three different killings and cannibalism of polar bear cubs by adult males, a behavioral response to food scarcity.

At the American Geophysical Union conference in San Francisco, Ross described the kills, showing her photographs of one of the most gruesome signals of global warming.
