Kassie Siegel: Polar Bears' Fate Now Rests With Obama
Year by year, the Earth's warming temperatures are robbing polar bears of the Arctic sea ice they need to survive -- the ice where they find their food and raise their young. But last month, scientists at the University of Bremen said that the extent of summer sea ice in the Arctic reached a historic low, retreating by some 50 percent since 1972.
The ice loss has been devastating for polar bears. Scientific literature is now rife with reports of starvation, cannibalism, drowning, more conflicts with people, increased mortality in both adults and cubs, and shrinking populations.
This species is being pushed inexorably toward extinction
