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. Michael Pollan, In Defense of Food: An Eater's Manifesto
