“Polar bears need to make their way onto the ice to feed and in 1987 the
bears were able to return to the ice by mid-November. This season, 2010, it
wasn’t until December 7th. That means that the bears are missing nearly an
entire month without the opportunity to feed properly. Scientists estimate
that the polar bear population in the Western area of Hudson Bay may be
extinct within 30 years.”
