is a 2008 American documentary film directed by filmmaker Robert Kenner. The Academy Award-nominated film examines corporate farming in the United States, concluding that agribusiness produces food that is unhealthy, in a way that is environmentally harmful and abusive of both animals and employees. The film is narrated by Michael Pollan and Eric Schlosser.
The film's first segment examines the industrial production of meat (chicken, beef, and pork), calling it inhumane and economically and environmentally unsustainable. The second segment looks at the industrial production of grains and vegetables (primarily corn and soy beans), again labeling this economically and environmentally unsustainable. The film's third and final segment is about the economic and legal power, such as food labelling regulations, of the major food companies, the profits of which are based on supplying cheap but contaminated food, the heavy use of petroleum-based chemicals (largely pesticides and fertilizers), and the promotion of unhealthy food consumption habits by the American public.
