Polar bear populations at risk…
Studies proceeded by the NASA with the Canadian Wildlife Service reveal changes in sea ice – stimulated by climate warming – might be affecting polar bear populations in five regions: Baffin Bay, Davis Strait, Foxe Basin, Western and Eastern Hudson Bay.
=> What can be noticed in summer:
* “…bears are to retreat to land & fast on their stored fat reserves until sea ice comes back…
* shortens the spring hunting season for female polar bears in Western Hudson Bay and is likely responsible for the continuing fall in the average weight of these bears. As females become lighter, their ability to reproduce and the survival of their young decline. Also, as the bears become thinner, they are more likely to push into human settlements for food, giving the impression that the population is increasing…”
