As Arctic sea ice melts, polar bears are changing their habitat, shifting from their preferred ice hunting grounds to land and open water, according to a new long-term study.
Polar bears depend on sea ice for hunting, breeding and denning. The bears wait for seals to pop up through breathing holes in the ice, but since the ice is melting earlier and earlier in the year, polar bears are shifting there habitat to land and water, and may be missing out on hunting opportunities.
