Polar bears can’t survive on land, but they’re trying to. They have to. As sea ice melts due to climate change, Polar bears can’t rely on their traditional diet rich in fish, seals, and other marine-based food. The bears are turning to terrestrial foods like berries, birds and eggs, but they’re not as healthy and their survival rate is threatened by this new diet. “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) and 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.
