When environmentalist Juan Rosario traveled to an Amish religious community in Iowa, to learn to make compost, he was surprised that they had a laboratory and the services of an expert in chemistry. What was a scientist doing in a place where people live far from technology and practice ecological farming with the simplest of methods? An Amish dressed in their style, with a wide-brimmed black hat, white shirt, and black pants and black jacket, pointed toward a large cornfield on a nearby farm. “The scientist helps us verify that pollen from genetically modified corn does not contaminate our crops,” he told Juan Rosario. “It’s the same corn that you develop in Salinas.”
