Polar bears need to be really fat in order to have healthy babies. But because of global warming, the bears aren’t as fat as they used to be, and they aren’t having as many babies.
Polar bears get fat when they can hunt a lot of seals. They can only hunt seals when there is sea ice for them to hunt from.
Global warming is making the sea ice melt. The bears don’t have as much time to hunt because the ice melts too early. Once the ice is gone for the year, the bears have to go to the shore.
