The Endangered Species Act was established in 1973 to protect endangered species. Climate change, caused by anthropogenic greenhouse gas emissions, has serious consequences for many species, but it is a great concern for polar bears. Polar bear populations are susceptible to climate change, hunting, and habitat alteration. They are the world’s largest terrestrial carnivore and because of their strength polar bears are the symbol of the Arctic.
Their physical characteristics make polar bears a perfect fit for the arctic. The polar bear’s oily and water-repellent fur allows it to easily shake off the water and ice that may have formed after swimming. Their thick layer of body fat and small ears enable them to conserve body heat. The bear’s white fur turns a yellowish color due to oxidation from the sun but still serves as camouflage. Their large paws have black pads covered with soft papillae, also called dermal bumps, which create friction and prevent slipping. Polar bears have partially webbed forepaws and elongated hind paws making it easy for them to swim (WWF: A Leader in Polar Bear).
