While the human race is trying to fight against global warming due to a threat posed to mankind by drastic consequences of climate change, the phenomenon is already having disastrous effects on lives of species in the arctic.

Polar bear cannibalism in the arctic has been studied before and is happening more regularly, since ice disappearing from the region is making it harder for polar bears to hunt seals. As males become desperate, they start hunting younger polar bears for food.

A video by National Geographic shows this tragic consequence of climate change captured on camera, where a female polar bear and her cub are seen running from an adult male who soon catches up on them and preys upon the cub.

The extreme changes in the climate are making it difficult for polar bears to find their typical food sources, leading to an increase in cannibalism.
