American farmers produced 600 more calories per person per day in 2000 than they did in 1980. But some calories got cheaper than others: Since 1980, the price of sweeteners and added fats (most of them derived, respectively, from subsidized corn and subsidized soybeans), dropped 20 percent, while the price of fresh fruits and vegetables increased by 40 percent.

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

A French poet famously referred to the aroma of certain cheeses as the ‘pieds de Dieu’—the feet of god. Just to be clear: foot odor of a particularly exalted quality, but still—foot odor.

Farms produce a lot more than food; they also produce a kind of landscape and a kind of community.

I think using waste oils as fuel makes sense. We do waste a huge amount of vegetable oil in this country and using that as a fuel source strikes me as fine.

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.
