Food Machine

Over the past century, an American industrial revolution has given rise to the biggest, most productive food machine the world has ever known. In this episode, host Yul Kwon explores how this machine feeds nearly 300 million Americans every day. He discovers engineering marvels we've created by putting nature to work and takes a look at the costs of our insatiable appetite on our health and environment. For the first time in human history, less than 2% of the population can feed the other 98%. How does this all work? Who are the men and women who keep us fed 365 days a year? Yul embarks on a trip across the country to find out.
