Polar bears are not only extremely unpredictable, but also very aggressive and will attack a human (territory or not.) There was only one recorded incident where a man found a Polar Bear cub and was able to play with the cub, then later as it became an adult, but, smart on his part he sent the Polar Bear back out in the wild where it belonged. Polar bears are extremely fast on their feet (more so than Grizzly bears) and will chase their victim until they drop. They are one of the only animals that will go out of their way to hunt you down and kill you. Not very friendly. Polar bears fight for food and when another polar bear is stealing their food and if other polar bears are bugging them.
