Polar bear hunting, harvesting and over-harvesting

Polar bears are harvested in Canada, Greenland, Alaska, and parts of eastern Russia (Chukotka area) under provisions set by the International Agreement. The numbers taken are regulated by quota in some areas, however, there are no legal limits to the number taken in some jurisdictions (see PBSG Proceedings for details). Annual harvest is between 500 and 700 bears or 2-3% of the world population of about 25,000 bears and is thought to be sustainable.
