The polar bear is a large bear found in the Arctic Circle noted for it's striking white fur. It spends most of it's time on the sea ice and hunts seals. Because of this, it is extremely vulnerable to changes in the polar icecap and is presently considered an endangered animal.
Some communities hold annual events called "polar bear plunges" on New Years Day or other occasions during the winter in which participants will enter nearby bodies of water and try not to freeze. No real polar bears are harmed during these events.
Actual interaction between humans and polar bears tends to be far less enjoyable; large, aggressive and not at all afraid of humans the polar bear is known to enter human communities all over the arctic circle where they will feed on rubbish, unattended food, domestic pets and people pretty much indiscriminately. Due to their swimming abilities and tendency to roam over large areas, such bear intrusions are hard to predict and prevent.
