Abstract
First paragraph:Recently I was a guest lecturer on food systems in a new seminar in the Department of City and Regional Planning at Cornell University. This was the beginning of the semester and only the second class. The department had never offered a course devoted to food systems before, and it was a bit of an experiment. My assignment as an alum of this department who had a specialty in food systems was to help introduce the topic. I had heard there was a lot of interest across the campus and the class might be a little full, but I was not prepared for the standing-room-only crowd in the classroom. I had to ask students to step aside so I could write on the blackboard.
