Over the past century, an American industrial revolution has given rise to the biggest, most productive food machine the world has ever known. Join host Yul Kwon to learn how this machine feeds nearly 300 million Americans every day. Discover engineering marvels created by putting nature to work, and consider the toll our insatiable appetites take on our health and environment. Embark with Kwon on a trip that begins with a pizza delivery route in New York City, then goes across the country to California's Central Valley, where nearly 50 percent of America's fruits, nuts and vegetables are grown, and into the heartland for an aerial look at our farmlands. Meet the men and women who keep us fed - everyone from industrial to urban farmers, crop-dusting pilots to long-distance bee truckers, modern-day cowboys to the pizza deliveryman.
