I think for real change to happen, it's going to have to come from the kids, the community, the teachers, the parents.

What we eat has changed more in the last 40 years than in the previous 40,000. The survival of the current food system depends upon widespread ignorance of how it really operates.

The obesity epidemic among American children is becoming so bad that I think there's a growing realization across the country that we've got to change what we're feeding our kids and that school may be a really good place to start.

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.

We're all connected by the system, and we all have to be a part, I think, of changing it.
