Red List Animals—Polar Bears According to IUCN's recent Red List of Threatened Species,the polar bear is listed as a “vulnerable” species that is threatened with extinction.Besides,a quarter of the world's species will be on their way to extinction by 2050 as a result of accelerating climatic changes directly linked to human use of fossil fuels.The latest findings show that the earth is warming faster than at any time in the past and climate change in the Arctic,where polar bears live,is expected to be among the greatest of any region on the earth.The influence of climate change is increasingly felt in polar regions,where summer sea ice is expected to decrease(by 50-100 percent over the next 50-100 years.Polar bears are predicted to suffer more than a 30 percent population decline in the next 45 years.We should protect the polar bear!
