As Wendell Berry has tartly observed, to take animals off farms and put them on feedlots is to take an elegant solution—animals replenishing the fertility that crops deplete—and neatly divide it into two problems: a fertility problem on the farm and a pollution problem on the feedlot. The former problem is remedied with fossil-fuel fertilizer; the latter is remedied not at all.
