Freedom From Man Caused Global Warming Myths

"Polar bears belong to the genus and species Ursus maritimus, which means, “sea bear.” The term sea bear is appropriate because, as you now know, polar bears depend on the sea for much of their diet.

Besides weathering extreme temperatures on land, polar bears go extreme off land, too. In fact, many polar bears spend a great amount of time in the water and on ice floes. Not only have their coats and paws evolved to help make them good swimmers, their body shape has, too. A polar bear’s body is more elongated and streamlined for swimming – they’re missing the shoulder hump of the brown bear. And, its neck is longer, which helps keep the polar bear’s head above water. 

Polar bears can swim approximately four to six miles per hour and have been spotted far out to sea and as much as a few hundred miles from shore or even on ice flow."
