27 February - Tuesday
International Polar Bear Day.
Every year on February 27, the world celebrates International Polar Bear Day (International Polar Bear Day), or, in the more familiar Russian version, Polar Bear Day. The main purpose of the Day is to disseminate information about polar bears and to draw public attention to the need for their protection. And by this date, traditionally environmental and environmental organizations are preparing various public events and educational activities. It is also said about the need to solve the problem of melting polar ice - the main reason for the threat of the disappearance of populations of polar bears. Another reason that threatens the life of polar bears is the development of oil fields with subsequent pollution of the environment. The data obtained in recent years indicate that the polar bear (Ursus maritimus) entered the path of evolution about five million years ago. His ancestor was a brown bear. But, unlike his brown relative, who inhabits the earth, the polar bear perfectly adapted to life in the Far North, among sea ice.
According to rough estimates of scientists, today there are approximately 20-25 thousand individuals of the polar bear in the world. Leading world experts studying polar bears, published data that of the 19 polar bear subpopulations - eight decreased, three remain stable, and one increased. It is still difficult to gather data on the remaining seven subpopulations. The melting of ice in the Arctic, as a result of global warming, could lead to the disappearance of two-thirds of polar bears by 2050. First of all, the International Day of the Polar Bear is significant for the five countries in which the populations of polar bears inhabit - Russia, Norway, Canada, Greenland and the United States of America (Alaska). In May 2008, the United States brought the polar bear to the Red Book with the status of a threatened species. Canada and Russia defined the polar bear's status as a "vulnerable species". It is important to remember that polar bears can be found only in the Arctic latitudes, near the North Pole. In Antarctica, near the South Pole, polar bears do not live.
