A polar bear shakes his body to remove water at the St. Felicien Wildlife Zoo in St. Felicien, March 5, 2009. According to Environment Canada, Canada is home of approximately 15,000 of the estimated 20,000-25,000 polar bears worldwide. The species is also listed as a special concern by the Committee on the Status of Endangered Wildlife in Canada while last year, the US listed the polar bear as threatened under the US Endangered Species Act because their sea ice habitat is melting down.
