Polar bears resort to cannibalism as Arctic ice shrinks

This is why we all have to do something, anything, to save our planet. Even compressing your trash in your trash bag will reduce the numbers of trash bags used. Do something good today.

Excerpts from the full article:

"The Arctic sea ice melt is a disaster for the polar bears," according to Kassie Siegel, staff attorney for the Center for Biological Diversity. "They are dependent on the Arctic sea ice for all of their essential behaviors, and as the ice melts and global warming transforms the Arctic, polar bears are starving, drowning, even resorting to cannibalism because they don't have access to their usual food sources."

Scientists have noticed increasing reports of starving Arctic polar bears attacking and feeding on one another in recent years. In one documented 2004 incident in northern Alaska, a male bear broke into a female's den and killed her.

In May, the U.S. Department of Interior listed the polar bear as a "threatened" species under the Endangered Species Act. In a news release, U.S. Interior Secretary Dirk Kempthorne stated, "loss of sea ice threatens and will likely continue to threaten polar bear habitat. This loss of habitat puts polar bears at risk of becoming endangered in the foreseeable future, the standard established by the ESA for designating a threatened species."

What is the future for Arctic sea ice? Some scientists believe that in just five years, the Arctic may be ice-free during the summer.

"The Arctic is kind of the early warning system of the climate," Meier said. "It is the canary in the coal mine, and the canary is definitely in trouble
