It’s not just the Arctic sea ice that is becoming dangerously thin, so too are the polar bears who are finding food harder to hunt. Climate change may be putting an iconic Arctic animal in even more danger according to a new study by the United States Geological Survey. Call it a climate change diet that isn’t good for the bears. According to a new study from the United States Geological Survey, polar bears are shedding pounds at a crucial time when they are supposed to be building up body weight. The bears’ energy requirements are rising at the same time as the changing climate. They rely almost exclusively on a fat-rich diet of seals, which are most efficiently hunted from the surface of sea ice.
