USDA Forest Service general technical report NC 21. St. Paul, Minnesota: U.S. Department of Agriculture, Forest Service, North Central Forest Experiment Station. p. 85. «In the north-central States, the intensive culture of certain species and hybrids of poplars presents the greatest opportunity to achieve maximum wood fiber production, provided that adequate provision can be made for control of the many insects and diseases that may attack them. [...] The [...] trend toward monoculture [...] increases the vulnerability of the cropping system to insects and diseases. The greatest potential for insidious disaster due to virus diseases is with monocultures of vegetatively propagated perennial crops.»

Consultado el 30 de noviembre de 2019. «Industrial monocultures—single crops where there was once diversity, and single varieties of each crop where there used to be thousands—are also blows against biological and genetic diversity. [...] Monocultures are weak, subject to insect blights, diseases, and bad weather.»

«What is a dead zone?». NOAA. Consultado el 18 de abril de 2015. «The largest hypoxic zone in the United States, and the second largest hypoxic zone worldwide, forms in the northern Gulf of Mexico adjacent to the Mississippi River. This image from a NOAA animation shows how runoff from farms (green areas) and cities (red areas) drains into the Mississippi. This runoff contains an overabundance of nutrients from fertilizers, wastewater treatment plants, and other sources.»
Union of Concerned ScientistsArchivado el 15 de mayo de 2008 en Wayback Machine. article The Costs and Benefits of Industrial Agriculture last updated March 2001. "Many of the negative effects of industrial agriculture are remote from fields and farms. Nitrogen compounds from the Midwest, for example, travel down the Mississippi to degrade coastal fisheries in the Gulf of Mexico. But other adverse effects are showing up within agricultural production systems—for example, the rapidly developing resistance among pests rendering our arsenal of herbicides and insecticides increasingly ineffective."
