A polar bear swims underwater in the Saint-Félicien Wildlife Zoo in Saint-Félicien, Quebec, in a picture distributed early last month. According to Environment Canada, Canada is home to around 15,000 of the estimated 20,000 to 25,000 polar bears in the world. The U.S., Russia, Denmark, and Norway are the other four countries or territories where polar bears can be found in the wild.
