"It takes a lot of energy to survive in the Arctic, especially when your dinner is disappearing with melting sea ice.Scientists who outfitted polar bears with Fitbit-like devices along Alaskas Beaufort Sea have found that the animals need to eat the equivalent of one ringed seal every 10 days to survive. When theyre not eating, the bears spend upwards of 70 percent of their daylight hours resting in an effort to burn as few calories as possible." - TakePart
