A 6-year-long study recently found that polar bears can swim for great distances. GPS collars were attached to 20 female bears, some with cubs. The swims documented lasted from 17 hours to nearly 10 days and covered between 33 and 427 miles (54 and 687 kilometers) in the southern Beaufort Sea.
There are no earlier studies on polar bear swims, but there was not enough open water in recent years for bears to swim such distances.
Polar bears rely on sea-ice in the Arctic to hunt their prey, seals, but this ice is melting earlier every year. Scientists fear that cubs especially will not survive long swims. Twelve of the 20 bears had cubs when the collars were fitted, but when 10 of the 12 were recaptured a year later, only 6 had cubs.

Polar bears do not cause global warming. In fact, polar bears are affected by global warming due to the shrinking of their sea ice habitat. The loss of sea ice reduces their hunting grounds and threatens their survival.
Global Warming does affect the survival rate of Polar Bears because Global Warming Melts the ice.
people and global warming
Global Warming.
Polar bears are not a cause of global warming. They are being affected by climate change in that their habitat is decreasing in size (as the sea ice is melting).
Countries and their citizens are trying to slow and maybe even stop global warming. This is the only thing that will help polar bears.
Because of global warming, you can't hunt polar bears

Stop global warming first
loss of ice due to global warming
It's not far for polar bears because we are putting them through global warming its not fair.
