Recent studies indicate that the Kara Sea population is more susceptible to pollution than any other population in the Arctic. However, as New Scientist reported, the two populations in question, in Northeastern Canada, in previous decades had faced grave risk to their survival due to over-hunting. These polar bears inhabit the northern areas of Canada, Alaska, Greenland, Norway, Russia and the Arctic. Studies show that 1,500 – 1,800 polar bears are surviving in the Icy Cape and Pearce Point.

Species the planet over have been suffering the effects, polar bears not least among them.

While hunting has long been an issue, global warming has done a number on polar bears' habitats in recent years, dramatically shrinking the polar bear population worldwide. In the Western Hudson Bay, an increase in numbers to 842 is accompanied by declining survival and birth rates. The bears in Greenland are less likely to migrate to the eastern Svalbard.

In Kane Basin 10 polar bears are killed on an average each year. In 2005, the IUCN reclassified them, from “least concern” to “vulnerable,” where they remain today. In Baffin Bay, Foxe Basin, and the Davis Strait, populations have likely increased, to 2,826, 2,585 and 2,150, respectively, with the latter population considered likely stable form 2007 to 2016.

Another reason for such a vast territory is that adult males must go and find their reproductive partner each year. And although increased commercial activities, pollution, disease, inadequate habitat protection are also considered threats, the number one reason for the bears’ decline is the loss of sea ice due to climate change.
