As global warming thaws Arctic sea ice, experts warn that the population of polar bear will drop by more than 30 percent by the 2050s.
The International Union for Conservation of Nature (IUCN) estimated that there are between 22,000 and 31,000 polar bears in the Arctic now but their livelihood is becoming rampant as their habitat shrinks. Based on the more recent projection of sea ice since 2008, IUCN director general Inger Anderson warns that climate change will continue to seriously threaten the survival of polar bears.
As the Arctic sea ice disappeared, the polar bears are spending more time on lands, which increase their contact with humans. In a Canadian town named Churchill, polar bears have already come in contact with humans as the ice season in the western Hudson Bay has fallen by about one day per year over the last three decades, reported the Guardians.
The situation of polar bears is worsening by human activities in the Arctic such as oil drilling. Moreover, as the temperature rises, the food chain is distorted which in turns devastates the ecosystem and the culture of indigenous communities in the Arctic for they have traditionally hunted the animals for food and fur.
