Polar bears are dying because sea ice is melting from global warming. Scientists think that 2/3 of all polar bears; including all in Alaska will be gone by 2050 due to losing 100% of their habitat. Global warming is causing the melting of sea ice and a decline in habitat and food, forcing the polar bears to swim farther distances than normal. The higher temperature is also causing the polar bears to overheat because of their layers of thick fur.
"The loss of Arctic sea ice in a warming climate could drive them to the brink of extinction in less than four decades," said Interior Secretary Dirk Kempthorne.
Just recently the polar bears were added to the endangered species list. Unfortunately, the government is trying to take away some rights entitled by this list. Many disagree that the polar bears are on this list, because of their present record population. Even though this is true, scientists have noticed that 25% of all Polar Bear populations are already declining in number.
There is a 90% chance that humans are causing global warming. It is up to people to fix the problem, before the polar bears have to pay the price.
