Polar bears in trouble

As the Guardian and other outlets reported this past year, receding sea ice, shorter icy periods, and general Arctic warming have led to dire conditions for these denizens of the far North. They’re losing the ice on which they hunt, on which they raise their cubs, on which they hibernate, and to which they are very specifically and distinctly suited in every way. As a result, some of their populations are dwindling and others are seeing many in their ranks go hungry as they try, miserably, to adapt. How to help: you can start by signing Polar Bears International’s petitions on behalf of both the bears and the ice. Meanwhile, let these amazing photos cause a twinge to your heartstrings. Find out how many polar bears are left in the world.
