The struggle that polar bears face is starvation due to global warming. They can only hunt when there is sea ice covering the Arctic Ocean during the winter. As the warm part of the year gets longer and the cold part gets shorter, polar bears have less time to hunt for food and more time to wait without it. Therefor, as the climate gets warmer, the more polar bears starve.
