FoodPolar bears are the main food of fish and seals. They are patient when hunting animals, waiting for prey (seals) that were diving for hours - hours until the target jumped to the mainland and then immediately attacked by a bear. Strength paralyze its prey is in sharp bear claws and a powerful blow from his paw.An adult polar bear fat requires the assumption of 2kg per day in order to survive at a temperature of the cold. A dog weighing 55kg sea to meet the reserve food for polar bears to survive for 8 days.
ReproductionMating season for polar bears occur in summer in the Arctic, ie between the months of March to June. Then the baby - a baby polar bear to be born in the month of December to January, usually they will give birth to 2-3 babies.

During pregnancy, the mother bear will dig a nest in a pile of snow and even sleep all winter in the nest until the baby - a baby bear was born. However, the mother bear did not feel dehydrated or short of food to feed a baby - a baby bear who has been born.The baby - the baby will live in the nest for approximately 28 months. The new baby polar bear born only for rats. It has no fur, blind, and weak at all. A female Polar bears mammals proved to be a parent greatest devotion in terms of keeping the child - their child.

FactAccording to a statement from the Institute of the United States Geological Survey (USGS, two-thirds of polar bear populations will become extinct in the mid 21st century. In recent decades the North Pole (Arctic) will lose a very large ice sheets. The experts even estimate that 40 percent of the habitat of polar bears will be destroyed in 2050.Therefore, in the late 1990s, the community development society in Chocrane region, Canada, founded The Polar Bear Conservation and Education Habitat and Heritage Village. Non-profit rehabilitation centers are designed specifically to protect polar bears. Opened for 365 days without rest to all the people who care about polar bear populations are threatened with extinction, to gain knowledge, learning, and direct experience of caring for polar bears.
