JAKARTA – Climate change and the warming of the earth’s surface have caused conditions to melt the ice sheet in the Arctic. This condition is also worrying for the polar bear population which is getting smaller and it is estimated that these animals will be threatened with extinction in the next 2100.

“What we’ve shown is that, first, we’re going to lose the survival of the cubs (polar bears), so the cubs will be born but the females won’t have enough body fat to produce milk to carry it through the season without ice,” he said. Polar Bears International chief scientist Steven Amstrup, who joined the research to AFP.

Amstrup shows how close the threat is to polar bear populations by around 2100, and that too in just a few populations if climate change continues.
Even in Queen Elizabeth Island, which is in the northernmost part of Canada’s Arctic archipelago, no more baby polar bears will be born. It is likely that this distant relative of the bear will become extinct in the 2080s.
Polar Bears Survive Without Food
In fact, polar bears can survive without food prior to reproduction. However, this condition is also influenced by regional conditions and adequate food supply, after the polar bear gives birth.
Adult females with juveniles are generally the second most vulnerable, followed by adult males and finally, females without cubs, some of whom can fast for 255 days before their chances of survival drop sharply.
It is known, this carnivorous animal can survive by relying on sea ice from the Arctic Ocean to hunt seals. Polar bears are known to be skilled enough to swim, but not very agile when it comes to catching seals in open water.
When the ice melts, these animals will be forced to travel long distances or to beaches, where they struggle to find food for their young. However, in recent decades, the warming climate has seen ice sheets in parts of the Arctic melt, causing bear populations to plummet.
This condition makes polar bears included in the list of animals vulnerable to extinction in the International Union for Conservation of Nature (IUCN), especially with climate change which is a determining factor in the decline in polar bear populations.
