Two US Department of Agriculture Secretaries, one past, one present, come together to talk about American food policies. Agricultural supports and other decisions made on US soil, and the trade agreements we negotiate around the world, have powerful effects on the global food supply; land conservation; the use of water, nitrogen, and pesticides; and animal and plant disease management. How do US policy choices impact the safety, price and accessibility of the food we feed the nation? How do we balance consumer and industry concerns to keep food affordable and nutritious while protecting the agricultural economy? Dan Glickman, Tom Vilsack, Corby Kummer
