Climate change is a phenomenon that negatively affects millions of plant and animal species around the world. Seeing their natural habitat modified, living beings have had to adapt their behavior, in some cases seeking to survive even in unexpected ways. According to The Guardian , cases of polar bears killing and eating each other are increasing in the Arctic, as melting ice and human activity erode their habitat. Polar bears. Polar bears resort to cannibalism due to lack of food. Ilya Mordvintsev, senior researcher at the Severtsov Institute of Problems of Ecology and Evolution in Moscow, said: Cases of cannibalism among polar bears are a long-established fact, however we are concerned that such cases used to be rare, and are now recorded quite frequently. At a presentation in St. Petersburg, Mordvintsev suggested the behavior could be due to lack of food. In some seasons there is not enough food and large males attack females with cubs. The increase in cases could also be due in part to more people working in the Arctic and reporting such behavior: We now get information not only from scientists but also from the growing number of oil workers and defense ministry employees.
This winter, the area from the Gulf of Ob to the Barents Sea, where polar bears used to hunt, is now a busy route for ships carrying LNG (liquefied natural gas), Mordvintsev said. The Gulf of Ob has always been a hunting ground for the polar bear. Now the ice has been broken for the whole year. Russia, already a key global oil and gas exporter, wants to develop its LNG potential in the Arctic. It has also significantly Job Function Email List upgraded its military facilities there. Another Russian scientist, Vladimir Sokolov, who led numerous expeditions with the Antarctic and Arctic Research Institute, said that this year polar bears were mainly affected by abnormally warm weather on Spitsbergen Island in the north, in the Norwegian archipelago of Svalbard. where there were no ice floes and little snow. Russian researchers have recorded increasing numbers of polar bears moving away from their traditional hunting grounds as ice melts due to climate change. Over the past quarter century, summer Arctic ice levels had fallen by 40%, Sokolov said. He predicted that polar bears would eventually no longer hunt on sea ice and would be limited to coastal areas and high-latitude archipelagos.
Russians living in Arctic settlements have raised the alarm over dozens of bears entering areas where people now live, particularly to raid garbage dumps in search of food. Other problems for bears and the destruction of their habitat Residents of a village on the eastern edge of Russia's Kamchatka Peninsula have been stunned to see a polar bear prowling for food hundreds of miles from its usual habitat. Russian media reported Wednesday that the exhausted-looking animal apparently traveled from Chukotka to the village of Tilichiki in Kamchatka, about 700 kilometers to the south. Environmentalists said the bear may have lost its sense of direction while moving on an ice floe. Vladimir Chuprov of Greenpeace said: Due to climate chang, the Arctic is warming, the hunting environment becomes smaller and less convenient. The ice is receding and polar bears are looking for new ways to survive. And the easiest way is to reach people. In this case, the locals made the bear feel welcome by giving it fish. Videos posted online showed the animal moving past residents, showing no aggression; However, authorities in Kamchatka prepared a rescue effort to transport him to Chukotka by helicopter. Polar bears' dependence on sea ice makes them highly vulnerable to global warming. The shrinking Arctic ice cover could increasingly deprive them of their usual prey.
