Polar Bears and Global Warming
Polar bears are totally dependent on the Arctic sea ice for all their essential needs. Already, the bears are suffering starvation, drowning, and population declines as the sea ice melts away Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss. Shrinking sea ice drastically restricts polar bears' ability to hunt their main prey, ice seals. The U.S. Geological Survey predicted that, based on polar bear distribution and current global warming projections, two-thirds of the world's polar bear population would likely be extinct by 2050. Reduced food availability due to global warming has also caused polar bears to resort to cannibalism off the north coast of Alaska and Canada
Polar Bears are now an endangered species
