When grizzly bear food is covered in snow during the winter, this species must den because there is nothing to eat. Sea ice platforms are moving farther apart: The retreat of ice has implications beyond the obvious habitat loss. They are about seven to eight feet long, measured from the nose to the tip of their very short tail. We are the last generation that can stop devastating climate change. Four of these populations are considered to be declining. They mainly eat ringed seals, but may also eat bearded seals.
Polar bears need sea ice to eat—hunting ringed seals as they come up for air or rest on ice across the Arctic—and to travel, find mates, and teach their cubs how.
Apr 1, A cold spring allows ice to linger, giving polar bears easier access to one of their favorite foods: seals. A warm spring cuts short the availability.

Endangered Species Act as threatened. After each summer, the trend seen in the Arctic is for sea ice to be farther from shore, making it necessary for polar bears to swim increasingly long distances from shore to reach the ice.

With changing temperature patterns and increased human activity in the Arctic, the ecosystem is vulnerable. The best way for people to help polar bears is by reducing carbon emissions and working with the National Wildlife Federation to campaign for reductions in climate change pollutants.
