The document summarizes information about two indigenous desert-dwelling groups: the !Kung people of southern Africa and the Shoshone people of Nevada. The !Kung live nomadically in small family bands and rely on hunting and gathering for food. They have an egalitarian social structure and emphasize sharing resources. The Shoshone also lived nomadically in family bands, exploiting different ecological zones and sharing food. Both groups faced challenges to their traditional lands and ways of life from government policies in recent decades.
