Polar Bears in Danger
Most polar bears could disappear by the end of the century. Global warming is to blame. This is according to a recent study. It was published by Nature Climate Change.
The study says most polar bear populations will drop by 2080. The cause is melting sea ice. Polar bears hunt seals on the ice. Without ice, the bears must roam on the shore. On land, they are away from their main food source. That means they could go hungry.
Marika Holland is one of the authors of the study. She says it is up to us to save polar bears. “I believe that there is hope,” she says. “But humans need to act quickly to turn that hope into a reality.”
