In addition to being relatively unstable agricultural ecosystems, monocultures are also vulnerable to disaster from social and economic disruptions.
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.
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.
There are many reasons why producers move to intensive grazing systems. These include...
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.
