The history of the twentieth century was dominated by the struggle against totalitarian systems of state power. The twenty-first will no doubt be marked by a struggle to curtail excessive corporate power.

So for everything I do, I'm very clear about what I'm doing, and I tell people what it's about. They get a sense of what I'm thinking. I don't let people think I'm going to write something in praise in the meatpacking industry, and then they read it and it's actually attacking the meatpacking industry.

By birth and upbringing, I think I'm emotionally resilient. I don't feel like I'm a depressive person.

There's also a growing trend toward having gardens in schools to literally show kids where food comes from by having them grow and prepare their own food. There's also a movement that's bringing farmers into schools and creating relationships between local farms and local cafeterias, so that instead of frozen mystery meat, you have fresh produce that's coming from the area that has a name and a face associated with it.

Students can do experiments and investigate for themselves what's going on in restaurants, in our food system, and begin a process of learning.

Basically, I'm a perpetual student. I start by finding a subject I really don't know very much, but that I'm curious about. I learn about it through books in a library, by doing interviews with people who know a lot about the subject, and by going out on my own and seeing for myself what's happening.
