Drastic Environmental And Polar Bear Change

710 words - 3 pages

Polar bears are the kings and queens of the Arctic. They are on the top of the food chain and have no other predators, and there strong bodies and layers of fat and fur allow them to survive the harsh conditions of the Arctic. The Arctic is a large body of frozen water with layers of ice sheets and is filled with glaciers. The regional climate of the Arctic is mostly cold and freezing temperatures that range from -40 to -60 degrees Celsius in the winter to about a high of -10 degrees Celsius in the summer. Polar bears are largely found within the Arctic circle all around the Arctic ocean. The habitat of the polar bear consists of the annual sea ice, which covers the water and the Arctic inner islands. They are usually found where the ice meets the water, in efforts to hunt for their main prey the Arctic seal. The seals surface from the water to breath time to time, and come out if little holes in the ice. Polar bears are aware of this and often search for these holes and wait for the food to come to them. They also may attack ones that are on ice or land resting. Polar bears are massive animals and can weigh anywhere from 400 - 1`500 pounds and measure 8-10 ft in length. These bears have up to 4 inches of blubber and have amazingly thick fur that traps heat and keeps them warm to help cope with the dangerously cold weather. Even now there is a problem that arises for these animals, which is global warming. Global warming refers to the constantly rising average temperature of the world due to things such as greenhouse gases and the greenhouse effect. This is a problem for the polar bears as it is a direct threat to their natural habitat the Arctic ocean and its ice sheets. These ice sheets are melting quicker and quicker every year and the shore line's keep on decreasing which mean that the polar bears will have nowhere to live and will not be able to hunt for their main source of food because there will...
