Polar Bears and the melting ice

This photo reminds me of how the melting polar ice caps will be affecting the Polar Bears. The bears need the ice to be able to hunt and rest on the ice and eat their catch. If they can't hunt on the ice they won't be able to gain enough weight to help them survive their hibernation. They can't afford to have a fast weight loss before their hibernation ends because there is nothing around for the to eat before spring.
