Alaskan Polar Bears Migrate To Russia Due To Climate Change

Global warming is one of the most important factors which affects animal population and habitats. Similarly, in Alaska, since temperatures have risen, polar bears have been forced to move to Russia's Wrangel Island. About 40 percent of the polar bear population in Alaska has dropped between 2001 to 2010. Annual Alaska's temperature has risen to 4.8° Celsius in the last 50 years.
