It is critical that the next president understand that her or his decisions regarding the growing, processing and marketing of food, biofuels and fiber will have tremendous impacts not only on American consumers, farmers and the environment, but also on agriculture and food systems throughout the world. Global trade deals, including the Trans-Pacific Partnership, will affect the quality and safety of food and the viability of farming in the U.S. and elsewhere. American leadership needs to be extremely attentive to the voices of farmers, rural communities and grassroots agrarian organizations — and not only to corporate Big Ag and the heads of state who are beholden to it.
