Polar bears 'facing extinction'

Polar bears
Polar bears could be extinct within the next 20 years if something isn't done to slow down global warming, a conservation group has warned.

The Worldwide Fund For Nature says the earth could heat up so much that some areas of ice and snow will melt in the Arctic, where the bears live.

If this happens, then food which the bears and other creatures live on will go too, and they won't survive.

The group is now calling for "drastic action" to prevent global warming.

"If we don't act immediately, the Arctic will soon become unrecognisable," said a spokesman for the group.

"Polar bears will be consigned to history - something that our grandchildren can only read about in books."
