In recent years the production of poultry, eggs and pork has increasingly been conducted on an industrial scale, as illustrated by a four-deck laying house in Pennsylvania. The concentration of swine facilities with their waste lagoons and sprayfields in North Carolina's Coastal Plain has raised new water-quality issues, explored by Michael A. Mallin in "Impacts of Industrial Animal Production on Rivers and Estuaries." (Photograph by Larry Lefever for Grant Heilman.)
