Coca Cola has partnered with World Wildlife Fund to try to save its favorite winter animal, polar bears. I came across the site for their campaign — pretty cool (no pun intended!). You can donate money and buy a virtual parcel of their Arctic habitat.
I hear that the situation for polar bears is getting desperate and that some of them have started eating their young (http://planetsave.com/2011/12/15/polar-bears-resorting-to-cannibalism/). Climate change and habitat destruction is making it harder and harder for them to survive.
