Polar bears are one of the living things on the earth. It lives on the poles of the earth. It is the largest carnivores on the earth. Polar bears are the last trophic level in the food chain. Polar bears have the thick fatty layer to keep them warm. Their have the white fur.

Human activities will lead to the extinction of polar bear. Global warming due to extensive use of chlorofluorocarbon (CFC), open burning, illegal logging and extensive burning of petrol.Global warming will cause the ozone layer to become thinner and thinner. This continuously cause the ultraviolet radiation passes down to earth. Global warming cause ice on north pole and south pole to melt. This lead to the extinction of wildlife on the two poles. 

As we are one of the living things on earth, we should play our roles to protect other living things from being extinction. We should use car pooling, ban illegal logging, stop to use chlorofluorocarbon and stop open burning. They have their rights to survive.
