These magnificent creatures face many threats to their survival: Hunting - finally being regulated by the five polar bear countries (Canada, Denmark, Norway, United States and Russia).Toxic Chemicals - mercury, PCB's, DDT.Pollution - oil spills and garbage, old tires, styrofoam, plastic, parts of car batteries are eaten by bears.Radio-active Material - disposed of in the sea.Global Warming - has reduced the ice season. The bears have fewer days to hunt for seals and fewer bear cubs are surviving. Jacques Cousteau said "The sea is a universal sewer."
