Polar Bears

With all of the buzz around Al Gore's Nobel Prize winning efforts, many are hoping the heightened awareness of global warming will turn some attention to the plight of the polar bears. It would be utterly heartbreaking if this incredible predator was relegated to zoos or worse, especially after hundreds of years of adaptation to the hostile Arctic environment. I was once lucky enough to see a family of polar bears in the wild in the high arctic, a mother and two cubs. What a great many people were not aware of until recently is that polar bears need the sea ice to freeze over. This gives the polar bears ideal hunting grounds for the seals that build dens and breathing holes in on the floes. Polar bears are classified as marine mammals and are surprisingly deficient in skills for catching prey on land.

There have been several reports of polar bears migrating into the northern boreal forests of Alaska and mating with grizzly bears, resulting in a hybrid bear. While this phenomenon is not entirely new, the frequency of the polar bear's forays into southern lands is bound to increase. Biologists fear the interbreeding could dilute some of the polar bears greatest (and least understood) adaptations, such as the ability to navigate incredible distances in a dynamic environment with few landmarks, their aquatic skills and the instinct to catch seals under sea ice.

Arctic studies have shown that over the years, the sea ice grows and recedes with somewhat normal consistency but the last few years have shown a massive recession, along with the retreat of hundreds of Arctic glaciers. Call it global warming or whatever you like, but I think the time to start "thinking green" is now--if nothing else, so the great white north stays north. We may never encounter polar bears in our normal lives and very few people will get to visit them, but that's exactly why we need to act now - to keep those wild places wild.

Aside from the resources above, the best thing you can do for polar bears is to reduce the effect your lifestyle has on global warming. Whether that means taking a bike to work or school, installing solar panels on your home, or just turning out the lights when you leave a room - every little bit helps.
