According to a study in Nature Climate Change, the population of polar bears will be in serious drop by the year
2080. The cause is melting(融化) sea ice. Without ice, the bears must walk on the bank which is away from their main food source. That means the animals will be in danger because of lacking food.
" There's not enough food on land to support a polar bear population." Doctor Smith, the study's lead writer said. Lacking of food induces another problem. Mother bears may not be fat enough to produce milk for their babies. Some bear populations could stop having babies, leading to a rapid drop in numbers.
Arctic(北极) sea ice usually melts in the spring and summer, and then grows in the winter. But now, the ice is taking longer to grow back. Weather reports say the Arctic is warming twice as fast as the rest of the planet. Ice here has reduced 13% every 10 years since the 1970s. The Arctic is home to about 25,000 polar bears. Scientists have known that the animals are in danger.
But the study also notes that it is still possible to slow Arctic melting. The world can reduce the burning of fossil fuels(石化燃料) and lower the greenhouse gas." Saving the polar bears is up to us, I believe that there is hope. But humans need to act quickly to turn that hope into a reality." Doctor Smith said.
