A third of polar bears will die out in 35 years because of ice thawing

Population of polar bears in the next 35 years will be reduced by a third because of thawing of the Arctic ices. Researchers from Security service of fish resources and the wild animal USA came to such conclusion.

By calculations of specialists, the quantity of polar bears on Earth in the next 35–40 years will decrease from 26 thousand at least to 17 thousand. Other forecasts assume reducing population for 80% that will threaten polar bears of extinction.

Floating ice floes are necessary for bears for hunting for seals who are very quick in water. Scientists divided bears into 19 subgroups, two of which already decreased because of shortage of ice.
