Another day it occurred to me that time as we know it doesn't exist in a lawn, since grass never dies or is allowed to flower and set seed. Lawns are nature purged of sex or death. No wonder Americans like them so much.

I made the unexpected but happy discovery that the answer to several of the questions that most occupied me was in fact one and the same: Cook.

When chickens get to live like chickens, they'll taste like chickens, too.

We do not subsidize organic food. We subsidize these four crops - five altogether, but one is cotton - and these are the building blocks of fast food. One of the ways you democratize healthy food is you support healthy food.

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.

A natural historian is somebody who looks at something in terms of its relationship to the rest of the natural world. You look at things ecologically. When you see a cow on a feedlot, you don't just see a cow; you see a cow that is eating certain food. You follow that food and that food takes you back to a corn field.

We are not only what we eat, but how we eat, too.
