Polar bears use arctic sea ice as a platform to hunt their favorite food, seals. Unfortunately, climatic warming is rapidly melting the ice. Without it, scientists warn, polar bears will not survive.
Why is ice important to polar bears?
For polar bears, the sea ice is a crucial platform for life. They use the ice to travel long distances to new areas. They hunt for seals by finding their dens or sitting next to gaps in the ice, waiting for the unsuspecting prey to pop up.
Do polar bears rely on ice?
Polar bears rely heavily on the sea ice environment for traveling, hunting, mating, resting, and in some areas, maternal dens. In particular, they depend heavily on sea ice-dependent prey, such as ringed and bearded seals.
What does a polar bear need to survive?
Polar bears need an average of 2 kg (4.4 lb.) of fat per day to obtain enough energy to survive. A ringed seal weighing 55 kg (121 lb.) could provide up to eight days of energy for a polar bear.
Do polar bears eat penguins?
Polar bears do not eat penguins, since penguins live in the southern hemisphere and polar bears live in the northern hemisphere.
Do polar bears drink water?
So they eat the blubber, not the meat. To break down and digest large amounts of protein, you need to get rid of the excess nitrogen in the protein by peeing it out in your urine. However, to produce lots of urine, you have to drink lots of water. There is no drinking water on the polar ice cap!
