Polar bears have long been the poster boys for the consequences of climate change. Now a new study suggests that Arctic species are at risk of extinction by the end of the century. The University of Toronto-led study, published in the scientific journal Nature Climate Change, says warming temperatures are causing sea ice to disappear, leaving polar bears increasingly struggling to find the food they need to survive.

According to the World Wildlife Fund, there are an estimated 22,000 to 31,000 polar bears in the world, although exact numbers are hard to determine because of their remote habitat.
According to a new study, polar bears are completely dependent on sea ice for hunting seals, their primary food source. But the extent of the ice is shrinking because climate change is steadily accelerating the rise in temperatures at the poles, keeping them on land where seals are harder to catch.
