A Vanishing Home
20,000-25,000 polar bears live in the coastal and offshore zones of Canada, Alaska, Russia, Greenland and Norway.
Their habitat is disappearing. Climate change is effecting the Arctic faster than anywhere on the planet, and the polar bear, like the canary in the coal mine, is a living signal of the harmful changes in the environment.
Polar bears are incredibly strong and resourceful. They can overcome scarce food, long swims, extreme cold, and attacks from predators.
But climate change is something they can’t deal with. Polar bears are thinner because they don’t have as much sea ice to hunt from, cub survival rates are down, and their population is dwindling.
Sylvia Earle on the Arctic
OWOO Science Advisor and Nat Geo Explorer in residence Sylvia Earle on this critical moment in history for the Arctic.
"when you take away the habitat of an organism, you lose the organism. if you lose the sea ice, it's pretty clear that you are going to lose (polar) bears."
-Dr. Andrew Derocher,
Chair of IUCN Polar Bear Specialist Group
