New study reveals the polar bear may become extinct by end of the 21st century because of climate change. They use it to hunt, perching near holes in the thick ice to spot seals, their favorite food, coming up for air. But as the Arctic has warmed twice as fast as the rest of the world because of climate change, sea ice is cracking earlier in the year and taking longer to freeze in the fall.
That has left polar bears — all 19 populations that live across the Arctic — with less ice on which to live, hunt and reproduce.
Oh stop. 😆
