The International Polar Bear Day is marked ever year on the 27th of February. First of all, this date is significant for 5 countries, where polar bears live – Russia, Norway, Canada, Greenland and the USA (Alaska).
In May of 2008 the USA brought in the polar bear to the Red Book with the status of a species being under the threat of disappearing. Canada and Russia defined the status of the polar bear as «a vulnerable species».
This day was founded for distribution of information about polar bears and attraction of attention of the public to necessity of their protection. Nature-protecting and ecological organizations prepare public actions and enlightenment activities. The talk is also about necessity to solve the problem of thawing of polar ices – the basic threat of disappearing of the animals. Development of oil fields with further environmental pollution is another threat for life of polar bears.
By evaluations of scientists, in the world there are about 20-25 thousand polar bears. Among 19 sub-populations of the polar bear: 8 decreased, three stay stable, and one increased. It is difficult to collect data about other 7 sub-populations, as it is informed on the portal calend.ru. Thawing of ices taking place in the Arctic can lead to disappearing of two third of polar bears till 2050.
