 | | Agriculture includes both subsistence agriculture, which is producing enough food to meet the needs of the farmer and family, but no more) and also (almost universally in the "developed" nations and increasingly so in other areas) the production of financial income from cultivation of the land or commercial raising of animals (animal husbandry). |
 | | Increasingly, besides food for humans and animal feeds, agriculture produces goods such as cut flowers, ornamental and nursery plants, fertilizers, animal hides, leather, industrial chemicals (starch, ethanol, and plastics), fibers (cotton, wool, hemp, and flax), fuels (methane, biodiesel, biomass), and both legal and illegal drugs (biopharmaceuticals, marijuana, opium, cocaine). |
 | | The practice of agriculture is often used to distinguish the neolithic period from earlier parts of the stone age. |
