Detail of Slide #102


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."
