Some men are worrying about potential baldness. But while the news that some Alaskan polar bears are losing their fur may not be among our most pressing current concerns, we wonder why.
Scientists with the U.S. Geological Survey have found that some polar bears have less hair. That could get chilly for the bears in the snowy land and icy water. Scientists say this is unusual, but "not unprecedented."
Also, last December, some seals were found dying -- and to have had sores and hair loss. Any connection?
Fortunately, though the polar bears may be a little chilly now, summer's not far off. No freezing deaths among the bears have been reported. But still, we wonder why some bears are losing their fur.
