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

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.

During my school visits, I really enjoy the feedback I get from them much more than anything I might tell say to them.

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 fast-food industry is in very good company with the lead industry and the tobacco industry in how it tries to mislead the public, and how aggressively it goes after anybody who criticizes its business practices.

Fast food is popular because it's convenient, it's cheap, and it tastes good. But the real cost of eating fast food never appears on the menu.

Yes, a cheeseburger and fries is probably my favourite meal. But I don't eat ground beef anymore.
