*Where do polar bears live?*
Polar bears live In the *Arctic* in areas where they can hunt seals at
openings in the sea ice called /leads/. There are five nations with polar
bears: U.S. (Alaska), Canada, Russia, Greenland, and Norway. Polar bears do
not live in *Antarctica*. Penguins do.
*Are polar bears endangered?*
Experts in polar bear science believe they are. They predict that as the
Arctic continues to warm due to climate change, two-thirds of the world's
*polar bears could disappear* by mid-century—although hope remains /*if
*/action is taken to greatly reduce greenhouse gas emissions.
Rapid *loss of sea ice* is their major threat. Others include pollution,

Species: /*U. maritimus*/
Polar bear range
The *polar bear* (/Ursus maritimus/) is a carnivorous bear native largely
within the Arctic Circle encompassing the Arctic Ocean, its surrounding
seas and surrounding land masses. It is the world's largest bear, together
with the omnivorous Kodiak bear (/Ursus arctos middendorffi/), which is
approximately the same size.^ A boar (adult male) weighs around
350â700 kg (770â1,500 lb),^ while a sow (adult female) is
about half that size. Although it is closely related to the brown bear, it
has evolved to occupy a narrower ecological niche, with many body
characteristics adapted for cold temperatures, for moving across snow, ice,
and open water, and for hunting the seals which make up most of its
diet.^ Although most polar bears are born on land, they spend most of
their time at sea. Their scientific name means "maritime bear", and derives
from this fact. Polar bears hunt their preferred food of seals from the
edge of sea ice, often living off fat reserves when no sea ice is present.
The polar bear is classified as a vulnerable species, with eight of the
nineteen polar bear subpopulations in decline.^ For decades, large scale
hunting raised international concern for the future of the species but
