From the International Business Times:
“The polar bear population is set to decline by about 7,800 bears – or 30 per cent of the global population – by the middle of the century, a new study has found.
The study supports the IUCN Red List’s classification of polar bears as a vulnerable species that has a high risk of going extinct in the wild.
Polar bears rely on sea ice for almost all aspects of life, but sea ice in the Arctic is diminishing rapidly due to anthropogenic climate change.
In some parts of the Arctic where polar bears live and hunt, more than four days of ice cover has been lost each year on average since 1979. The less days of ice cover there are, the less opportunity there is for polar bears to hunt.”
