From Scientific American : Nine years ago someone sent Bronx high school teacher Stephen Ritz a box of spring bulbs. “I didn’t know what to do with them, so I stuck them behind a radiator, and they got forced”–meaning they sprouted into bloom from the heat. That accidental sprout was the germ of an idea that has rocketed Ritz and his students into new lives of growing hundreds of thousands of pounds of fruit and vegetables, operating farmers’ markets in food deserts, learning science, improving their health, getting certified to build mobile urban farms and green roofs for A-list clients from Rockefeller Center to the Hamptons, earning a living wage, and transforming their neighborhood, all in the poorest congressional district in America.
