... Corn’s triumph is the direct result of its overproduction, and that has been a disaster for the people who grow it. Growing corn and nothing but corn has also exacted a toll on the farmer’s soil, the quality of the local water and the overall health of his community, the biodiversity of his landscape, and the health of all those creatures living on or downstream from it.
