Food manufacturers are greenwashing their packaging, using homey organic colors and themes to sell food that isn't even necessarily organic or healthy. "Start with a gentle image of a field or a farm to suggest an ample harvest gathered by an honest, hard-working family. To that end, strangely oversize vegetables or fruits are good. If they are dew-kissed and nestled in a basket, all the better. A little red tractor is O.K. Pesticide tanks and rows of immigrant farm laborers bent over in the hot sun are not."
