USGS: Polar Bears Cannot Survive on Land

A new report from the U.S. Geological Survey paints a grim picture for the future of polar bears. Forced onto land as their icy habitats melt, polar bears will be unable to thrive on terrestrial food, such as berries and birds.

Polar bears have one of the fattiest diets of any species, and the high-protein, low-fat food available on land is no match for the ice seals upon which polar bears have been preying for generations. Furthermore, a polar bear would be unlikely to gather enough terrestrial food for long-term survival thanks to competition from grizzly bears.

"The smaller size and low population density of grizzly bears in the Arctic provides a clear indication of the nutritional limitations of onshore habitats for supporting large bodied polar bears in meaningful numbers," said Dr. Karyn Rode.
