Polar Bears Can’t Thrive on Land-Based Diet

Posted by Mike Confino, April 3, 2015


Polar bears are increasingly feeding on land-based foods instead of their traditional marine prey as climate change reduces the sea ice they use as hunting platforms — a dietary change that has contributed to declining health and survival rates among the species, a team of scientists led by the U.S. Geological Survey (USGS) has found.

“While it’s tempting to think that polar bears could survive by switching to a terrestrial diet, this paper establishes in no uncertain terms that land-based foods do not offer any hope of polar bear salvation,” said Steven Amstrup, the chief scientist for conservation group Polar Bears International (PBI), who is a co-author of the study, which was published Wednesday in Frontiers in Ecology and the Environment. Scientists with the USGS, PBI and Washington State University participated in the research.
