 Polar Bears Might Soon Be Driven to Extinction By Melting Sea Ice

A climate-change expert has warned that polar bears could soon disappear from parts of the Arctic due to global warming.

And those that survive may become darker as they crossbreed with brown bears.

Cambridge University's Professor Peter Wadhams said that Arctic summer sea ice, already melted to its smallest area on record, could totally collapse in three years.

"As their habitat shrinks, we could see a process of 'de-evolution' as polar bears revert back to becoming more like brown bears, hunting salmon in rivers," the Daily Express quoted him as saying.
