Agriculture

The production of food through the raising of crops and/or animals. The development of agriculture approximately 9,000 years ago is considered to be one of the most important revolutions in human thinking, one that made civilization possible. The trade of agricultural products, such as wheat or coffee, gave rise to the first exchanges. Even now, agricultural products are among the most important commodities that are traded. Very often, agriculture may only be performed in certain areas. Zoning laws regulate where farming and ranching may or may not take place. See also: Agribusiness.
