...think of agriculture as something the grasses did to people to conquer the trees.

My hope is that if people have the knowledge, and if they actually see where their food comes from and have access to the information, they will make better ethical choices.

Ripe vegetables were magic to me. Unharvested, the garden bristled with possibility. I would quicken at the sight of a ripe tomato, sounding its redness from deep amidst the undifferentiated green. To lift a bean plant's hood of heartshaped leaves and discover a clutch of long slender pods handing underneath could make me catch my breath.

I work very hard on finding good characters who can explain things to me, and I use them to help tell the story. I organize my pieces not just around people but around animals and plants, energy flows, the path that carbon takes through the food system.

I've always been interested in plants because I'm a gardener, so I have a basic understanding of botany and things like that, but it's all self-taught.

What an extraordinary achievement for a civilization: to have developed the one diet that reliably makes its people sick!

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.
