The Eskimo are the indigenous peoples who have traditionally inhabited the northern circumpolar region from eastern Siberia (Russia), across Alaska (United States), Canada, and Greenland. The traditional lifestyle of these people (Inuit) is adapted to extreme climatic conditions; their essential skills for survival are hunting and trapping. Agriculture was never possible in the millions of square kilometres of tundra and icy coasts from Siberia to Northern America and Greenland. Therefore, hunting became the core of the culture and cultural history of the Inuit.
