A group of polar bears has adapted to hunting without sea ice, which suggests some members of the species might survive as the Arctic heats up
, which is free of sea ice for most of the year. Polar bears typically need sea ice to survive, so the discovery is raising hopes that some members of the species might survive the loss of ice caused by climate change.
Polar bears need access to Arctic sea ice to hunt for seals. So, with sea ice in the region diminishing because of global heating, the animals are expected to near extinction by the end of this century.
