Southeastern Indians hoped for meat or fish, but they depended upon vegetables. Many wild plants produce food for a few weeks each year, but only a few staples are available year around. Survival is possible without agriculture, but finding enough food for everyone can be a difficult, full-time job. The Indian population of Tennessee (42,146 sq. mi.) was about 20,000. It thus took 2 sq. mi. of land to produce enough wild food for one Indian. The Europeans could grow enough food for one person in a half acre garden.
