Agriculture is the cultivation of animals, plants and fungi for food, fiber, biofuel,
medicinal plants and other products used to sustain and enhance human life.
Agriculture was the key development in the rise of sedentary human civilization, whereby farming
of domesticated species created food surpluses that nurtured the development of civilization.
The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials.
Specific foods include cereals (grains), vegetables, fruits, oils, meats and spices.
Fibers include cotton, wool, hemp, silk and flax.
Raw materials include lumber and bamboo. Other useful materials are also
produced by plants, such as resins, dyes, drugs, perfumes, biofuels and ornamental
products such as cut flowers and nursery plants.
