Polar Bears vs. Global Warming: How Are Bears Faring?
Thanks for taking the quiz! Find out how you did
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.
How is global warming impacting some polar bear populations?
Fewer cubs are born or survive to become adults
Many adults are increasingly skinny
Bears are forced to swim longer and longer to find ice, from which to hunt for food
CORRECT! - All of the above In a recent trip to the Hudson Bay, National Wildlife Federation staff investigated reports of skinnier-than-normal polar bears. Sadly, there is already filmed footage of cubs dying of starvation.
What fraction of the world's polar bears do scientists project we could lose by 2050?
CORRECT! - Two-thirds The U.S. Geological Survey projects that two-thirds of polar bears will disappear by 2050. This dramatic decline in the polar bear population is occurring in our lifetime, which is but a miniscule fraction of the time polar bears have roamed the vast Arctic seas.
What is the status of polar bears on the Endangered Species List?
CORRECT! - Threatened The Secretary of the Interior listed the polar bear as threatened throughout the United States but is currently allowing oil and gas development in the polar bear's habitat in Alaska.
They are not on the list
BONUS: Which law already on the books can be used to fight global warming and help polar bears?
Clean Water Act
CORRECT! - Clean Air Act The Supreme Court rules that the Environmental Protection Agency has the authority under the Clean Air Act to regulate carbon dioxide emissions.
