Polar bears eat seals. Seals swim faster than bears do, so the bears need a big area of ice floating on the sea. The bear waits by a hole in the ice. When a seal comes up through the hole for air, the bear is ready. Polar bears need food, and that's why they need ice. I don't know why or whether they need snow.
Polar bears don't need ice, they are adapted to the ice. Which means they are addicted or may live well than any other place in the world in the artic.
That is their primary means of hunting (seals).
Polar bears, though excellent swimmers in ice-cold waters, are land animals. If one is far offshore and a floe is nearby, maybe it will clamber up onto the floe to have a nap.
It provides a surface to hunt on and to travel on.
cause they get too warm
yes
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.
Polar bears main eat seals, which they hunt from the ice. During summer, when much of the sea ice melts, polar bears find ift difficult to find food.
Penguins, polar bears, sea lions, etc.
Polar bears are surrounded by ice and other cold sea animals. They live way in the Antartica. So they are surrounded by freezing water and lots of ice.
global warming, melting of sea ice...
by global warming...Sea ice losses in the Arctic fromglobal warmingare the major threat to polar bears. Polar bears depend on sea ice for hunting, breeding, and in some cases, denning. In 2012,summer ice lossesin the Arctic were larger than the size of the United States.
Polar bears are found, not in the ocean, but in the land and ice floes surrounding the Arctic Ocean.
No. Polar bears really don't live in caves, they live out on the sea ice.
Polar bears aren't much troubled by the rising sea levels, as they aren't particularly interested in what goes on at the coastline anyhow. The big problem for the polar bears is the temperature. The warmer it gets, the longer it takes for the ice to form. and polar bears use the ice sheet to hunt for seals from.
No because it is hot in Hawaii. Polar Bears only live in the Polar Regions of the World.no
Will they survive global warming and melting of sea ice?
The ice at the North Pole is constantly melting because: Pollution clogs up the atmosphere, so it traps greenhouse gases inside the Earth. Greenhouse gases keep us warm, so they're normally a good thing, but now we have wayyyyy to much. Polar bears need ice to live on. (hello, they can't swim forever!) Also, they catch their fish through holes in the ice.
