Polar bear

The rapid melting of ice is forcing polar bears to increasingly move by swimming in search of a place of residence.

Because of melting ice polar bears have to make a long journey on the water, found by biologists from the University of Alberta.

Scientists watched hundreds of polar bears and found – when the ice begins to melt, the animals are able to make a 9-day trip across the ocean in search of a more suitable place of residence.

According to the researchers, such a long journey is harmful to polar bears: journeys across the ocean, they almost do not eat and do not rest. In an average week-long trip, the animal loses to 22% fat.

Often to find a new home, the bears travel with their pups. So, in 2009 during a 9-day trip was killed one-year-old polar bear.
