London: Amid global warming, polar bears have shown remarkable resilience to adapt to changing climate. Scientists have noted the species change their hunting and eating habits. However, the change has also brought forward a disturbing behaviour.
In a troubling video released by National Geographic, a polar bear is seen resorting to cannibalism.
The video shows an adult polar bear chase and kill a young cub even as her helpless mother battles in vain to save her child.
