Agriculture is the term for cultivation of animals, plants, fungi, and other life forms for food, fiber, biofuel,
medicinal and other products used to sustain and enhance life. The term “Husbandry” infers cultivation of fauna rather than flora.
The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. Specific foods include grains, vegetables, fruits, oils, meats and spices. Fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo.
Over one third of Earth's workers are employed in agriculture, second only to the services' sector, although the percentages of agricultural workers in developed countries has decreased significantly over the past several millennia.
