10-year study shows polar bear decline


A 10-year study shows that polar bears in Canada’s northwestern Arctic have declined in health and abundance.

The study of the Southern Beaufort Sea population suggests bear numbers dropped by about 40 per cent between 2001 and 2010.

Bears numbers have stabilized at the new lower levels.

Scientists say that may be because the predators have found new food sources or new ways to hunt.

But report co-author Steve Amstrup says those new tricks aren’t likely to be a permanent solution to the loss of sea ice, which the bears use as a hunting platform for seals.
