International polar bear day
February 27th every year is "International Polar Bear Day". This holiday was established to remind everyone to pay attention to the living conditions of polar bears and Arctic ecology.
Global warming
Global warming and sea ice continue to melt are not a good sign for polar bears. The habitats that polar bears rely on for survival have been crushed like never before. The World Meteorological Organization (WMO) predicts that Arctic sea ice area will decrease by 54,000 square kilometers every year.
According to estimates from the World Wildlife Fund (WWF) and the International Union for Conservation of Nature (IUCN), the number of polar bears currently living in the wild ranges from 22,000 to 31,000. In 2015, the (IUCN) included the polar bear in the Red List of Threatened Species and rated it as a "vulnerable" species. The Convention on International Trade in Endangered Species of Wild Fauna and Flora lists polar bears as a species that is “not yet in danger of extinction but may be endangered.” The IUCN predicts that the global polar bear population will decline by more than 30% by 2050 due to the loss of sea ice habitat, one of the many consequences of climate change.
Fact
It is widely believed that the only effective measure to protect polar bears is to curb global greenhouse gas emissions. Combined with the protection of local people, these measures may save polar bears from extinction within a few decades.
When polar bears ask for food or other things from their companions, they greet each other with a nose-to-nose salute. If a bear is polite, it will be allowed to share food with its peers.
