Polar bears could become extinct by 2100
Most polar bears will become extinct by the end of this century if global warming continues, a study published on July 20, 2020, said.
- Polar bears hunt seals on sea ice. But as temperatures rise, hunting opportunities will decline for the animals. If they are unable to hunt and eat, they won’t be able to reproduce as a result.
- If greenhouse gases are emitted at their current rate, only polar bears living in the Queen Elizabeth Islands in Canada’s Arctic Archipelago will remain by the end of the century.
- But even if emissions are curbed, sea ice will continue to melt, leading to a decline in the polar bear population, the study said.
