MonocultureMonoculture is a common practice in modern agriculture in which large acreages of land are planted with one type of crop, usually multiple years in a row. Often such techniques are used to supply goods to other regions or countries. Monocultures deplete the soil and crops grown in this manner become more susceptible to pests and disease than those grown in a diverse crop environment, thus requiring larger amounts of chemical sprays (i.e. pesticides). Monoculture on animal factory farms refers to the raising of one type of animal (generally chickens, turkeys, cattle, or pigs) confined in densely packed expanses, often treated with hormones and antibiotics to maximize growth and prevent the diseases that would otherwise spread quickly through the farm. These operations produce much more waste than the surrounding land can handle, and the farms are associated with numerous environmental hazards as well as animal cruelty. The government calls these facilities Concentrated (or Confined) Animal Feeding Operations (CAFOs).
