Polar Bears are in danger due to global warming melting their habitat, the Arctic. Polar Bears and other animals could live if everyone makes enviormental contributions.
- Because of Polar Ice Cap melt
- Arctic shrinkage is the decrease in size of the Arctic region (as defined by the 10 °C (50 °F) July isotherm). This is a change in the regional climate claimed to be a result of global warming while others say its caused by changes in local wind currents. Projections of sea ice loss suggest that the Arctic ocean will likely be free of summer sea ice sometime between 2060 and 2080.
As of 2008, the World Conservation Union reports that the global population of polar bears is 20,000 to 25,000, and is declining. In 2006, the IUCN upgraded the polar bear from a species of least concern to a vulnerable species. It cited a "suspected population reduction of >30% within three generations (45 years)", due primarily to global warming
