Polar Bears vs. Global Warming: How Are Bears Faring?

Thanks for taking the quiz! Find out how you did below.

What is the biggest threat to polar bears caused by global warming?
  • Warmer weather in the north that encourages more oil development in polar bear habitat
  • Less snow so polar bears' camouflage is less effective
  • CORRECT! - Loss of sea ice habitat, which makes it harder for bears to find enough food. Polar bears must hunt from sea ice for their food, primarily seals. As the ice disappears, bears are unable to hunt for the seals on which they depend.

    National Wildlife Federation staff investigated reports of skinnier-than-normal polar bears. Sadly, there is already filmed footage of cubs dying of starvation.
