its the only suitable environment they can live in, the conditions in which they live on the pack ice are more or less perfect for them and key to their survival. they would find it extremely difficult to adapt to any other kind of environment.
Polar Bears are native to the pack/sea Ice of the Arctic. There are therefore to be found in the countries which border this pack Ice, including Greenland, Norway (Svalbard), Canada, Alaska etc.
The world was much warmer than this era during the time of the Roman Empire. The Arctic Pack Ice probably melted during the summer at that time. Some Polar Bears have started hunting on land in Alaska instead of being totally dependent of hunting on the ice pack. Since Polar Bears survived two thousand years ago in the absence of a summer ice pack and they have taken up hunting on land, a number will survive global warming.
Polar bears are called ice bears by some.
The polar bear is depended on the arctic ice pack to hunt seals. With the disappearance of the ice pack polar bears are quickly becoming extinct. I have seen a polar bear attempt to prey on Walrus and get mangled by the tusks of the great beasts. There is a small population of Polar Bears surviving at Moose Factory Manitoba living off of the town's garbage dump.
Yes, global warming has reduced the ice pack on which they hunt seals.
Temperatures in the Arctic are rising at almost twice the rate of the rest of the world, and this is causing the early break-up of sea ice. Polar bears are dependent on the ice for their survival, which they use as a hunting platform, to secure mates and to travel.
Melting sea ice is a threat to the polar bears because without the sea ice the polar bears predators will see them and swim away.
They haven't. Polar bears are now a threatened species. If the polar ice cap goes, then so do the polar bears, as they rely on oceanic ice to secure their food.
Polar bears do not live in the ocean but do swim some in the Arctic Ocean. They live in the Arctic where they hunt seals on the ice pack.
THey live in the polar ice because their fur and they are used to that temperature
Warm ice melts and turns into water, and no. Polar bears dont walk on water...
Not very good. Numbers are dwindling and their Arctic Sea ice pack is getting smaller every year. Their natural prey, seals, are not easily found in their dens below the ice, and Polar bears are being forced onto land to compete with brown and other bears for food.
