Polar Bears are very vulnerable to climate change and human hunting. Due to their sheer size, they have no natural predators except themselves. Large males have been known to kill off younger/smaller bears to cut out on competition. Man has been hunting these giant carnivores for centuries for its skin and fur. As of now, approximately 20000 to 25000 animals exist in the Arctic wilderness. Their numbers are steadily declining due to habitat loss and hunting. Oil and Gas exploration in the Arctic too is a significant cause for the decline in Polar Bear numbers. Due to human activity and global warming, the ice caps are melting. So, the effective land that the bears have for hunting is coming down. Pollution too is killing off prey species. So, everything put together is endangering the species.
