A farmer is a person who is engaged in agriculture, raising living organisms for food or raw materials. This is a way of life that had long been the dominant occupation of human beings since the dawn of civilization. Related, but much different, is gardening.
The term farmer usually applies to a person who grows field crops, and/or manages orchards or vineyards, or raises livestock or poultry. Their products are usually sold in a market or, in a subsistence economy, consumed by the family or pooled by the community.
