Global warming to wipe out two third of polar bears by 2050: Study

polar bears in arctic

Hundred years from now, we may very well be seeing the end of the land’s largest carnivore, polar bear, if something is not done soon.
Yes, you’ve read it right! The pace with which we are adding to global warming is making more and more species enter the Endangered Species List and the polar bear is one such specie that is becoming vulnerable to warming temperatures and may soon be listed as a threatened species under the Endangered Species Act.

The new findings paint a sobering picture for polar bears. Report conducted by U.S. Geologic Survey predicts that two-third of the world’s polar bear population will have disappeared within 50 years, as global warming continues to destroy the Arctic ice they depend on.

Polar bears are adapted to the icy conditions of the northern icecaps. They depend on sea ice as a platform to hunt seals which is their primary food. Climate change is continuously decreasing the sea ice and this year, has witnessed the lowest extent of Arctic sea ice ever recorded.

According to the latest figures by National Snow and Ice Data Center, sea-ice extent had fallen to 1.70 million square miles, beating the previous record low of 2.05 million square miles set on September 21, 2005. With this figure, we can well imagine the effect of Global warming. The region is responding much faster to global warming than is widely thought.

The present polar bear population in the Arctic, according to the World Conservation Union is about 20,000 to 25,000. It is estimated that there will be a decline of about 42 percent in polar bear population by mid-century.

Whether it’s the polar bear or any other endangered specie, we can’t run from the fact that a common thread that runs between the future of all endangered species is human beings. Human beings are root-cause of the environmental problems and only humans can be the solution.
