What is the range of polar bears in Canada?
In Canada, they inhabit ice-covered regions from the Yukon and the Beaufort Sea in the west, to Newfoundland and Labrador in the east. They also range from Northern Ellesmere Island south to James Bay. Two-thirds of the global population of polar bears are found in Canada.
What kind of habitat does a polar bear live in?
Range of Habitat. The southernmost range of polar bears is limited by the amount of sea ice available, from which the bears can hunt for food. They also prefer traveling on ice, and so are generally found in coastal regions.
How big is the home range of a polar bear?
A large home range may be in excess of 350,000 sq. km (135,135 sq. mi.). Large home ranges can be found in the Bering or Chukchi seas. Polar bears don’t mark their home ranges. Polar bears undergo seasonal migrations, following the movements of the ice pack.
How many miles does a young polar bear travel?
When a young polar bear grows up, it may travel more than 1,000 kilometers to set up a home range apart from its mother’s, although this remains a scarcely studied topic, because tagging and tracking a quickly maturing animal is tricky. Scientists believe that most polar bears limit travel to home ranges of a few hundred miles.
How many polar bears are there in the world?
Based on subpopulation estimates, and presumed densities in areas where numbers are unknown, as of 2015 the IUCN/SSC PBSG estimates that there are approximately 22,000–31,000 polar bears across the Arctic. The current range covered by these subpopulations represents a total land and marine area of approximately 23 million km2.

What are the dangers for polar bears?
Threats to polar bears Climate change. Climate change, and the loss of sea ice habitat, is the greatest threat to polar bears. Toxic pollution. As top predators, polar bears are exposed to high levels of pollutants through their food. Oil exploration. The oil and gas business is increasingly moving into the Arctic as more accessible reserves in the south dry up.
How many of polar bears are left on Earth?
While hunting has long been an issue, global warming has done a number on polar bears’ habitats recently. In fact, the World Wide Fund for Nature (or WWF) estimates that there are only 22,000 to 31,000 polar bears left in the world. Are polar bears endangered 2019?
