"Part of agriculture is in the economy and part of it is not. Adherents of this perspective usually cite the activity of harvest as the dividing line. Cultivation, planting and growing up to the point of harvest is seen as a cultural, tending activity. Once harvesting has taken place, the food takes on a commodity character and enters the economic process."
If economic preoccupations and forces drive decisions on cultivating, environmental and social aspects are neglected.
