Polar Bear Habitat Melting Rapidly

Things are going from bad to worse for Ursus maritimus

The rapid melting of Arctic sea ice due to anthropogenic global warming has been well documented. The current sea ice extent is 50% of what it was in the 1950s.

Without the ice, polar bears cannot find food. Many of them drown miles away from the shore in search of something to eat.

Though polar bears are the object of trophy hunters and also have to compete with industrial fishing, global warming has become their single biggest threat.

In 2007, the extent of the ice reached a record low. And now, the U.S. National Snow and Ice Data Center (NSIDC) has reported that the sea ice is at its lowest level ever for this time of year and is on track to break the previous record.

At this rate, two-thirds of the world's polar bears will be gone by 2050.
