Facts about polar bears...

I don't get it. If polar bear is of great importance, so, why the extinction?
The Polar bear is easily the most recognizable symbol of the arctic. Nanuq, (polar bear) derives all of its food from the sea and is seldom found far from the drifting pack ice. Polar bears live mainly on the sea ice, hunting ringed seals, which is their primary source of food. Traveling on the sea ice, in search of seals can result in home ranges of 50,000 to 350,000 square km for an individual bear. Although polar bear meat is considered delicious it is never eaten raw like other meats because it carries many parasites. The polar bear liver is never eaten or fed to the dogs because it causes Vitamin A poisoning, which results in severe illness or even death. Polar bear meat, like most country foods, is an excellent source of iron and protein. Polar bear fat provides Inuit with Vitamin A and omega-3 fatty acids which helps reduce the risk of heart disease. Polar bear meat is usually baked or boiled in a soup or stew. The hide of the polar bear is quite remarkable; each hair is able to trap ultraviolet light and conducts radiation to the black surface of the skin, where it is absorbed. Polar bear pelts are used to make clothing, but this practice is not widespread here in Canada as it is with the Inuit of Greenland. This may be due to two reasons, the first of which is, caribou and sealskins are more abundant, and two, the general nature of the polar bear hide, it is wiry and bulky making it difficult to turn into comfortable winter garments.
