Polar bear facts
The scientific name for the polar bear is Ursus maritimus, which means 'Sea Bear' in the Greek language. Polar bear facts show that polar bears are found through out the ice covered waters of the Arctic region and prefer to remain out at sea all year long if possible.Scientists estimate there are between 25,000 to 40,000 polar bears in the world. Polar bears have an excellent sense of smell and can locate a seal up to 40 miles away. This makes them excellent ocean hunters. Polar bears facts show they are mainly meat eaters, and their favorite food is seal. They will also eat walrus, caribou, beached whales, grass, and seaweed. Polar bears are patient hunters, staying motionless for hours above a seal's breathing hole in the ice, just waiting for a seal to pop up.
A dense, thick undercoat of fur is protected by an outer coat of long guard hairs that stick together when wet, forming a waterproof barrier to keep them dry. Even though polar bears look white, their hair is really made of clear, hollow tubes filled with air. Blubber helps insulate polar bears from the freezing air and cold water, and acts as a nutritional reserve when food can't be found. Polar bear facts show that this blubber also helps the bears float in the water. It is 2 to 4 inches thick.
For a while, polar bears were in trouble. People killed them just for sport, and they were losing some of their wild places to live as people started moving into their territory. Global Warming has affected polar bears as well, the ice sheets are melting, preventing the bears from traveling in search of food. Many countries got together to help this magnificent bear by preserving its habitat and setting up hunting restrictions. Polar bears are doing better now, but they still need our help. People must continue to give polar bears large, safe places to live, and try to keep the enviorment clean and free of pesticides that could poison the bear's food.
