Polar bears are the world’s largest terrestrial predators that have been threatened by the unfortunate consequences of global warming. Due to the accumulation of gases trapped in the earth’s atmosphere, a large portion of the ice, especially from the Hudson Bay area, is thinning and breaking apart.

Polar bears usually settle themselves on packed ice during the winter to become closer to their food source, which includes seals. However, according to the World Wildlife Fund Organization, the sea ice is melting earlier in the spring, leaving these large carnivorous land animals to travel back to land. Without enough fat reserves stored after hunting, polar bears become thinner, which therefore affect there ability to procreate.

There is currently an estimate of 22,000 polar bears living today in the Arctic Region. Based on the research of the Environmental News Service, for the past 20 years, the population has declined a total of 22% in Hudson Bay. They also claim that a decrease of 30% will occur in another 35 to 50 years if this global pollution continues.
