The polar sea ice is shrinking each year. Each year the winter sea ice melts faster. Polar bears need to bulk up in winter by eating seals. Now they have a shorter time for feeding. The Hudson Bay bears are forced onto the land during summer where they compete for food and living space with humans and other animals. Food shortages mean that bears are weaker, fewer cubs are born and those that do are more likely to die.
