Whales have a thick layer of fat under their skin called blubber. For many years, the Eskimos of Alaska depended on these whales to live. Every part of a whale was used: the bones, the blubber, and the skin - every bit of it. In this way, one whale could feed an Eskimo community for a long time. They were important to the Eskimos. However, sometimes a good thing can get out of control and become a bad thing. This was what happened in whale hunting.
