Polar bears shed pounds with the thinning of Arctic Sea

Polar bears shed pounds with the thinning of Arctic Sea which in turn is due to climate change diet, and that not a good sign for the polar bears. They condemn global warming and faltering ice cover on the Arctic Ocean that is seal hunting weather for the bears.

The scientists for observing the bear’s patterns attaching tracking collars on their necks to furnish the nine female white giants, the tracking collars had video camera which enabled their monitoring and measuring their weight. The scientists discovered that five bears lost weight and four of them shed 2.9 to 5.5 pounds (1.3 to 2.5 kilograms) per day. The standard polar bear observed weighed about 386 pounds (175 kilograms). One bear shed 51 pounds (23 kilograms) in just nine days.

U.S. Geological Survey wildlife biologist Anthony Pagano, lead author of a new study in Thursday’s journal Science said that you are vociferating about a magnificent amount of mass to lose. The researchers observed the bear for ten days in April when they were happened to gain weight so they can reproduce later, provide food for the cubs and stay put through jarring winters. However, due to climate change the layer of ice is diminishing, therefore the bears are having a tough time grasping seal pups even during the peak time of hunting. The United States Fish and Wildlife Service mark Polar Bear as a threatened species.

Polar bears hunt through ice. They wait cautiously till the seal would come out in the open air to breathe, when it does so the bear with its claws makes the seal its food.  If the ice is broken and thin then the bear often has to swim to catch its prey which would have grave consequences on the health of the bear like hypothermia and risk of death.
