As a child of the Midwest, I’ve been surrounded by farms and farmers my whole life. Most of my immigrant forebears were farmers, and there’s a good chance that yours were, too. Although I’ve chosen a city lot instead of my grandfather’s alfalfa fields (at least for now), I’m quite interested in what will happen in the 2012 Farm Bill. The Farm Bill affects not just farmers, but everyone who eats -- and that’s all of us. The bill, with its grand scope and billions of dollars, will help define what we eat (and, thus, who we are) in thousands of subtle ways.
