As the Earth's atmosphere changes every day, animals all over the world are facing the threat of extinction, and the latest one to join the endangered species are the polar bears.

The Christian Science Monitor reported that in an interview with Rebecca Noblin, the director for the Center for Biological Diversity in Alaska, said, "Polar bears are in big trouble. There are other steps we can take to slow the decline of polar bears, but in the long run, the only way to save polar bears in the Arctic is to reduce greenhouse gas emissions." 

Tech Times has learned that in a published report by the U.S. Fish and Wildlife Service, the polar bears are dying at an alarming rate, and scientists believe that the main reason for this phenomenon is climate change.

Immediate action is needed to save the polar bears. Research shows that reduction in greenhouse gas emission may take years. U.S. Geological Survey representative Mike Runge said, "Because carbon emissions accumulate over time, there will be a lag, likely on the order of several decades, between mitigation of emissions and meaningful stabilization of sea ice loss." 

Live Science reported that people living in the Arctic can see the effect of climate change every day. Sea ices are melting and fires are frequent. The people's livelihood is at risk and polar bears are not excluded from the threat that climate change brings.

One may fail to see the significance of ice melting in the sea, but sea ice is primarily the hunting ground for food for polar bears. The polar bears are now looking for alternative source of food which is quite limited.

This is not the first time that this is being reported. Back in 2008, the U.S. Endangered Species Act (ESA) included the polar bears in their list.
