The population of polar bears in the Arctic could disappear within 20 years. Such a prediction in an interview with NSN did TV presenter and zoologist Nikolai Drozdov.
According to him, due to the lack of food in the region is in a difficult situation. Males do not eat in the fall and go dormant. Females at this time produce offspring that need to feed. On reproductive performance are also affected by active melting of ice in the spring. The ice cover moves away so that the bear is swimming to get to bear and overcome by the icy water a few kilometers.
“It is human disturbance that has endangered the existence of subpopulations. People should turn to nature’s face,” — said Drozdov.
Earlier in the journal Nature Climate Change published the results of research scientists from Canada and the USA, which analyzed the circumstances of the life of polar bears in the Arctic and on the basis of this predicted their extinction by 2100. According to the calculations of authors, in 80 years will disappear in 12 of the 13 studied populations of animals due to the melting of sea ice and lack of food. Thus the birth of the cubs will be possible across most of the Arctic. The exception may be only the island of Queen Elizabeth.
