From the website of the Union of Concerned Scientists:

“Misguided federal farm policies have encouraged the growth of massive confined animal feeding operations, or CAFOs, by shifting billions of dollars in environmental, health and economic costs to taxpayers and communities, according to a report released today by the Union of Concerned Scientists (UCS). As a result, CAFOs now produce most of the nation’s beef, pork, chicken, dairy and eggs, even though there are more sophisticated and efficient farms in operation.”

The UCS has released a report entitled CAFOs Uncovered: The Untold Costs of Confined Animal Feeding Operations which “enumerates the policies that have allowed CAFOs to dominate U.S. meat and dairy production.”
