Polar 2
The surface area of the polar ice sheets is decreasing. This adversely affects polar bear populations because it leads to a decrease in the size of their habitat. This in turn leads to the concern that they will have less opportunity to hunt for food.
It's notoriously difficult to measure the precise number of polar bears, but it's generally agreed that their total population is less than 25,000 and falling. Unfortunately, even conservative estimates predict that there will be no polar bears left only a century from now, in large part due to the effects of global warming.
