This is what climate change looks like. This starving polar bear was spotted by National Geographic photographer, Paul Nicklen, while on an expedition in the Baffin Islands. As temperatures rise, and sea ice melts, polar bears lose access to the main staple of their diet—seals. Starving, and running out of energy, they are forced to wander into human settlements for any source of food. Feeding polar bears is illegal. Without finding another source of food, this bear probably only had a few more hours to live.
