Polar Bear Extinction
Polar bears are becoming extinct because of the lack of food and a places to live. Since polar bears live on icy areas in the arctic, there habitat is rapidly being swallowed by vast oceans because of global warming.
Global warming has been a huge problem for several decades. Global warming is a problem because the ozone layer is being affected by pollution on earth. Air pollution destroys and contaminates the precious gasses that organisms need for survival. The ozone protects the organisms from harmful UV rays. The direct sunlight is making living conditions extremely difficult for arctic ecosystems to survive. Because polar bears mostly eat seal, they can not eat when there are slim amounts of land. The Pilar bears have to wait for the ice to freeze back in order to eat again.
Polar bears are being trained to be scared of humans so that they don't be fooled and actually hurt by them. Polar bears often wonder into human civilizations in search of food. Techniques to train them are rubber bullets, airhorns, flares, or a whack on the nose with a stick.
The Churchill polar bear population has been cut in half in the last 20 years from 12,000 to 670.
