Polar bears are mammals that live in the arctic sea ice and are directly affected by climate change. They are a key indicator of the health of the Arctic.
The current scientific consensus places the worldwide polar bear population between 20,000 and 25,000 animals.
In the middle of winter in some of the coldest places on Earth, female polar bears give birth to cubs. Litter size is most commonly two cubs, but sometimes litters can be one, three, or, very rarely, four cubs.
Unlike other bear species, polar bears are almost exclusively meat eaters (carnivorous). They mainly eat ringed seals, but may also eat bearded seals.
