Polar bears are found in five nations: Canada, Russia, U.S (Alaska), Denmark and Norway. However, the rough estimate is that there are between 22,000 to 40,000 polar bears living today, of which more than half live in Canada.Polar bears are not really endanger, but scientist are predicting that from the cause of the global warming they are on the line of danger. Polar bears could become extinct if the sea ice changes continue.
