Pamela Ronald and Raoul Adamchak have every reason not to get along. Ronald, a plant scientist, has spent her past two decades manipulating rice from her lab bench, bending the grain's DNA to her whim. Adamchak, meanwhile, is an organic farmer, teaching college students the best practices of an environmentally gentle agriculture at his California market garden. As Adamchak confesses, few have been more vociferously opposed to the genetic engineering practiced by Ronald than his organic movement, which has steadily grown in recent years to constitute an influential, if tiny, part of the U.S. farm system. So it can come as some surprise when Ronald and Adamchak let slip that they have been happily married for more than a decade. Such a union should not be shocking, the couple argues. And a more modest version -- sans marriage -- must be considered by any farmer or consumer hoping for a sustainable future for agriculture.
