Habitat
. The artic is on the top of the earth . The
polar bear is a mammal that lives on Arctic .The
entire circumpolar Arctic region is polar bear
habitat
3
Its appearance
  • The polar bear is the largest bear in the world.
  • Adults weigh 650 to 1100 pounds (295 kg to 498 kg
    ) Males are larger than females. A polar bear's
    coat can be from white to yellowish in colour.
  • When the bears come ashore in the summer they eat
    plants and berries.

4
  • They have thick oily fur coats and a layer of fat
    under their skin. When bears come out of the
    water they shake the water off their coats. The
    polar bear is so strong it can kill an animal
    with one blow to the head

5
Its foods
  • In late summer and early autumn the bears go
    along the coastline looking for dead whales and
    dead walruses. They also eat lemmings, arctic
    foxes and birds.Their favourite food is the
    ringed seal. The polar bear waits by the seal's
    breathing holes in the ice and quickly snatches
    the seal when it pokes its head out of the hole.

6
What it can do
  • Polar bears are able to swim in the icy Arctic
    Ocean without dieing of the cold temperatures.
  • The polar bear is nomadic. It travels to find its
    food.

7
How many are left?
  • Scientists estimate that there's about 22,000 to
    27,000 polar bears left on the Artic
  • The impact of man is decreasing the population of
    the polar bear. This happening by green house
    gasses (global warming)
  • hunting , less of food and other human impacts

8
The human impact
  • The impact on the polar bears population is
    decreasing every year by the green house gasses
    and hunting by humans. The way the problem is
    being dealt with the future of the polar bears
    could be few.

The Food Chain
10
Future of polar bears
  • The future of the polar bears can be changed if
    the problems of the polar bears
  • are resolved. The polar bears will be around for
    years to come we must stop the killing of the
    polar bears.

11
Life and death
  • .Polar bears can live 20 to 30 years, but only a
    small proportion of polar bears live past 15 to
    18 years
  • . Evidence of human polar bear hunts have been
    found in 2,500- to 3,000-year-old ruins. Arctic
    peoples have traditionally hunted polar bears for
    food, clothing, bedding, and religious purposes.

12
how the polar bears keep warm
  • Polar bears have white, thick, creamy fur that
    helps them keep warm and is a good camouflage on
    the snowy landscape. An average male polar bear
    weighs over 1,000 pounds and is about ten feet
    long. A female polar bear is much smaller. They
    are about eight feet long. Sometimes Alaskan
    polar bears weigh over 1,500 pounds.
