How do polar bears act around people?

Polar bears are curious animals and may approach humans out of curiosity. However, they are also very powerful and unpredictable animals, and any interaction with them should be avoided. If you encounter a polar bear, remain calm and slowly back away. Do not run, as this may trigger the bear's predatory instincts. Make yourself look as large as possible and try to appear non-threatening. If the bear continues to approach, shout and make loud noises to scare it away. As a last resort, you may need to use a weapon to defend yourself.
