Global warming causes the ice in the polar bears' habitat, the Arctic, to get thinner, rupture, and melt. Swimming conditions then become more difficult, food (seal) becomes scarcer, and reproduction rate decreases.
Disease and Parasitism - The trichinella is commonly found under the blubber of seals, the polar bear's main prey. After the polar bear eats the seal, this parasitic roundworm can get too close to the heart or cause severe pain under the bears muscle tissue, it could result in death.
Hunting - Many natives in the arctic kill polar bears for food, clothing, or handicrafts. Other times polar bears are killed in protection of property or in self-defense.
With a vulnerable population of over 20,000 animals, the polar bear is currently not an endangered species. With new restrictions on trophy hunting, the great ice bear's numbers may continue to rise.
