Common Name: Polar Bear
Scientific name: Ursus maritimus
Polar Bears live on
arctic sea ice
continental coastlines along or near coasts
Polar Bears are found in:
Norway Svalbard Archipelago
Threats that polar bears are going through are:
Oil and Gas Spills
Hunting and poaching
How Do Humans Continue to Impact the Natural Environment of Polar Bears?
POACHING FOR PRODUCTS
POACHING FOR FUR
The Inuits hunted polar bears, mainly for:
Polar Bear meat
they depend on sea ice as a platform to hunt, rest and breed
every year the sea ice is decreasing in size and melting for longer periods of time
as the ice starts to melt the polar bears won't have anything to walk or hunt on
many polar bears face malnutrition especially female with cubs
as a result of malnutrition male polar bears become predators of baby cubs
temperatures in the arctic are rising twice as fast then the rest of the world
as the temperature rises it is causing the ice to melt and the sea to rise which is very bad for polar bears
have to swim long periods of time to find land and food
often drown during in search of food and ice land
Melting Ice Caps
Shelter and Movement
- its effect on polar bears-
largest land carnivore
male polar bears grow up to 10 ft and weight 1400 pounds
female polar bears grow up to 7 ft and weight 650 pounds.
they are vertebrates
the coat of a polar bear can vary from pure white to yellow to light brown depending on the season and angles of light
the average lifespan of a polar bear is 20-25 years
Humans now poach polar bears for their fur to later make clothing and accessories for warmth.

Humans hunt polar bears for their products to make money from them:
Polar bear cubs learn to freeze and remain still while their mother hunts. If they move, the mother disciples them, with a whack to the head
