Melting of Arctic ice led to an increase in the incidence of white bears
Due to the increase in the temperature in the Arctic, white bears faced with a growing threat of infection with viruses, bacteria and parasites, which they almost did not encounter 30 years ago. This, as the BBC writes , is said by the results of a study during which scientists studied the blood samples of bears living in the Chukchi Sea. First, researchers analyzed blood samples collected in the period from 1987 to 1994, then collected and studied the samples obtained from 2008 to 2017.
