The largest source of pollution in the country — our industrialized agricultural systems, including CAFOs — also happens to be the most under-regulated. Governmental and independent researchers have fully documented the horrendous impacts CAFOs are having on our surface and groundwater and airways in countless studies. A 2008 Union of Concerned Scientists report estimates that the price to clean up the contamination under hog and dairy CAFOs in the country would be over $4 billion dollars, while the United States Department of Agriculture has put the cost to simply move the manure around to avoid over application on our lands would exceed a billion dollars a year. But regulation, clean-up and application of manure in agronomic amounts isn’t in the cards. Instead, CAFO’s continue to poison our communities with excess nutrient pollution that kills waterways and an overuse of antibiotics that kills humans with virtual immunity.
