I think that there's some brainwashing going on with this idea that we don't have time to cook anymore. We have made cooking seem much more complicated than it is, and part of that comes from watching cooking shows on television-we've turned cooking into a spectator sport. ...My wife and I both work, and we can get a very nice dinner on the table in a half hour. It would not take any less time for us to drive to a fast-food outlet and order, sit down, and bus our table.

The big journals and Nobel laureates are the equivalent of Congressional leaders in science journalism.

Those externalized costs have always included labor. It is only the decline over time of the minimum wage in real dollars that's made the fast food industry possible, along with feedlot agriculture, pharmaceuticals on the farm, pesticides and regulatory forbearance. All these things are part of the answer to the question: Why is that crap so cheap? Our food is dishonestly priced. One of the ways in which it's dishonestly priced is the fact that people are not paid a living wage to process it, to serve it, to grow it, to slaughter it.

Once you introduce the issue to young people and suggest to them that they have the ability to vote with their forks, either by positively going for certain kinds of foods or rejecting other kinds of foods, they realize that this is a responsibility and an opportunity to shape the world a little bit by their own choices.

The food system is a very complex beast. There are people who are going to get their food at Wal-Mart or at Safeway; they're not going to the farmers' market. Those people need choices too.

Meat is a tremendous environmental challenge. It contributes enormous amounts of greenhouse gas, especially beef eating.

I think there's a real tension between capitalism and morality. That's not to say these systems aren't powerful and useful, but to assume that capitalism can somehow assure moral behavior or character, that's just a pipe dream.
