<human>: Is it true that polar bears are going extinct due to global warming?
<bot>: Yes, it is true that polar bears are going extinct due to global warming. The Arctic ice cap is melting and the polar bear population has been declining since 2007. Polar bears need sea ice for hunting seals and their habitat is shrinking as temperatures rise. As of 2020, there are only 20,000-25,000 remaining in the wild.
