The energy I was sensing in audiences was political energy, as much as anything else.

Originally, the atoms of carbon from which we're made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life-the carbohydrates, amino acids, proteins, and lipids-is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.

I think historically modern economics, capitalist economics, tends to erode moral categories... And this is where I think the right gets capitalism wrong. They kind of assume that there is a moral equivalence or moral valence to capitalism, but I tend to think that economics erodes all the kind of cultural taboos and inhibitions and values it comes into contact with.

When you go to the grocery store, you find that the cheapest calories are the ones that are going to make you the fattest - the added sugars and fats in processed foods.

If you can't pronounce it, you shouldn't be eating it.

I mean, we're really making a quantum change in our relationship to the plant world with genetic modification.

When you're cooking with food as alive as this -- these gorgeous and semigorgeous fruits and leaves and flesh -- you're in no danger of mistaking it for a commodity, or a fuel, or a collection of chemical nutrients. No, in the eye of the cook or the gardener ... this food reveals itself for what it is: no mere thing but a web of relationships among a great many living beings, some of them human, some not, but each of them dependent on each other, and all of them ultimately rooted in soil and nourished by sunlight.
