Explain why the bison was necessary to the plains indians. give examples

Bisons were of extreme importance for the Plain Indians. When they would catch it, they would use every single part of it. The meat can be eaten, the skin can be used for clothes or building tents, the bones can be used for pretty much anything, varying from jewellery to weapons. Bisons were a part of their life and that's why the colonies wanted to kill them so as to weaken the Indians.
