Polar Bears Lives are Changing

Polar bears hunt seals on ice.  When the ice melts they move back to land and fast, waiting for the ice to come back.  In some parts of the world, the water is now frozen over 2.5 weeks less a year, meaning that polar bears have 2.5 weeks less a year to hunt, eat and store up energy for their fast.
