HUNTING
The Inuits hunted polar bears, mainly for:
Fur
Polar Bear meat

Kamilk
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
