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

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.

The United States now has more prison inmates than full-time farmers.

When you go into a fast food restaurant, you may just think about how good your meal tastes while you're eating it. But you're not thinking about all the consequences that come from that one purchase - the consequences for your body, the consequences for supporting this company and how it's treating it workers, all the way back to the farm where the potatoes were grown, or the ranch where the cattle were raised.

I've written about illegal immigrants in the United States; I spent a year following migrant farm workers as they were harvesting. I've written about our criminal justice system, and how it treats the victims of crime. I've been working for years now on a book about prisons in America, and I've been going into prisons and traveling around the country and seeing what's going on.

We can have Americans eating affordably and eating in a way that's sustainable.

The way we eat has changed more in the last 50 years than in the previous 10,000…. Now our food is coming from enormous assembly lines where the animals and the workers are being abused, and the food has become much more dangerous in ways that are deliberately hidden from us. This isn’t just about what we’re eating. It’s about what we’re allowed to say. What we’re allowed to know.
