The Inuit, who used to be called "Eskimos," are the people of the Canadian Arctic. They have adapted to the freezing cold surroundings, where they depend on marine life for food. In the area, vegetables and trees are hard to find. The Inuit hunt land animals during the summer with traditional weapons, such as bows and arrows. Their primary means of transport is sleds pulled by dogs. In order to protect their body from the extreme cold, they made clothing out of caribou fur. Another interesting fact about the Inuit is the igloos, houses made of snow blocks, in which they live during winter.
