Polar bears may be wiped out by the end of the century unless more is done to tackle climate change.
This was the findings from a recent scientific study.
Scientists believe some Polar Bear populations have already reached their survival limits as the Arctic sea ice shrinks.
The bears rely on the sea ice of the Arctic Ocean to hunt for seals.
As the ice breaks up, the animals are forced to walk for long distances.
Polar bears are listed as vulnerable to extinction by the International Union for Conservation of Nature (IUCN).
