Agriculture affects most aspects of everyday life from experiences of culture and providing the food people eat to underpinning and enabling the economic processes that let people accrue wealth and prosper. Agriculture allows for the existence of cities by decentralizing food supplies and distributing crops, meat and other foodstuffs between population centers by means of a complex network of transportation.
Agriculture supplies the food modern populations rely on. Most people do not farm or raise livestock on their own land, and so they are dependent on local or commercial producers of foodstuffs in order to survive and live their lives in the styles to which they are accustomed.
Agriculture intimately affects the modern economy of the United States. It is part of a general move toward urban population centers which consume and process rurally produced food and enable processes of trade both domestic and international, with farm trade abroad making up a significant portion of many major farms' revenue bases.
Farms also produce the raw materials used in many chemical and commercial processes, including the manufacture of certain pharmaceuticals. The connection between farms and the pharmaceutical and medical industries relies on farms' ability to grow plants and herbs in large concentrations over short periods.
