Polar bears have to swim continuously for 687km to feed

A polar bear had to swim for 9 consecutive days, with a 687km long distance, a new study published in Polar Biology magazine said.

Scientists say that the polar bear must swim farther to find food is a phenomenon of climate change that makes the Arctic ice melt faster and faster . This also means that the distance between icebergs is far away.

Scientists from the Geological Survey (USA) have attached a GPS tracking device to the polar bear neck to monitor their activities. During the follow-up, the team found a mother polar bear swimming continuously for 9 days.

'This polar bear swims continuously for 232 hours with a distance of 687km under the cold water of 2-6 degrees Celsius. We are amazed at this polar bear's ability, but this can be permanent affect the next generation of this bear, 'said Dr. George M. Durner, a member of the research team.

Difficulties are waiting for the next generation of polar bears

Polar bears often have to move between icebergs to hunt seals as food. Therefore, having to travel at a long distance will cause polar bears to consume a lot of energy. This may make bears less fertile, affecting the next generation.

Currently, polar bears have been placed in the Red List by the International Union for Conservation of Nature (IUCN). This is one of the most endangered animals because their habitat is increasingly destroyed by climate change.
