It's really a shame that my favorite animal in the world is becoming extinct. Polar bears are finding themselves having less and less ice mass to live on, harder to hunt, produce their young.. etc.. I mean this is just a synopsis of what's happening to a LOT of other species. They're not used to the hotter temperature so they migrate higher up in altitude on mountains or higher up north so they can survive...

The polar bear could be driven to extinction by global warming within 100 years, warns an ecology expert. The animal, which relies on sea ice to catch seals, is already starting to suffer the effects of climate changes in areas such as Hudson Bay in Canada.

Scientists say Arctic sea ice is melting at a rate of up to 9% per decade. Arctic summers could be ice-free by mid-century.
