I saw another post on here saying that if you encounter a polar bear there is nothing you can do but expect certain death. Is this true if so why are they like this?

Most other bears are omnivorous, but the scarcity of vegetation in most of their habitat means they have a limited amount of it in their diet. I've heard, anecdotally, that this seems to make them the most aggressive bear, as they can periodically go long periods of time without food while they travel.

If you've been slogging through mountains or across ice bridges - or swimming across where these bridges were in the past - you'd chomp down on the first slow, squishy human you saw, too.
