Polar bear encounters with humans on the rise, more put in Churchill jail

" Canada is home to two-thirds of the world's polar bears, but experts say climate change could make the Hudson Bay population extinct within a few decades.
Polar bears depend on winter hunting to build up enough fat to carry them through the lean summer months on land when food is scarce. But Arctic waters now don't often freeze up until early December and thaw much earlier in the spring. That leaves polar bears with less time to bulk up on fatty seal meat while on the ice.
As the bears spend more time on land with less fat, they grow hungry and can venture into town in search of food. Where the first encounters with polar bears used to be late August, Hedman said polar bears are now coming into contact with people as early as July 1."
