The global warming and the damage that is generated to the ozone layer produces various negative consequences to nature. One of the cases is the thaw that affects the habitat of polar bears and triggers a drastic change in diet thereof. This can be verified in a video where the bear hunting reindeer.
It is about a large female who chased a male reindeer in the glacial water, was able to catch it and took it to dry land to devour it. The stark scene occurred in the Svalbard archipelago, in Norway, and revealed how these animals have changed the type of food with which they feed as a result of the fact that their old prey are no longer as frequent as before, as has happened with the seals.

The audiovisual was filmed by members of the team of a scientific station. “It was so amazing that it was like watching a documentary. You could almost hear the voice of the narrator in the background saying that this event absolutely had to be seen because we would probably never see it again, “he said. Izabela Kulaszewicz and AFP.

This unusual fact surprised scientists, to the point that Kulaszewicz decided to publicize the event in a magazine specialized in the development of animals. This article, according to the researchers’ gaze, shows how polar bears have changed their focus on their prey due to the melting that is taking place in glaciers.
This has been reflected in extensive signs of predation between polar bears and reindeer, since where the audiovisual was recorded they coexist 300 bears and 20 thousand reindeerTherefore, larger mammals have chosen to eat their smaller, four-legged pairs. Specifically, according to specialists, this behavior has two possible explanations: the one mentioned above, where the retreat of the marine glacier has led the bears to live longer on land, changing their diet; and on the other hand the increase in reindeer numbers in Svalbard.
Days later, the bear repeated feeding patterns
After being seen eating a reindeer, the animal, two days later, was observed devouring another reindeer carcass. This last animal is a good food option in summer, when there are not many seals, which turn out to be the favorite food of white hunters due to their calorific fat.

“Reindeer can be important, at least for certain bears, when they must remain on land for long periods,” said the expert. Jon Aars. However, this change in behavior would not be a salvation for the extinction of the species since it is estimated that by 2,100 they will have completely disappeared.
