Organic, Local, Seasonal, Low on the Food Chain

Eat foods that are at once organic, local, seasonal and low on the food chain. Local keeps down the transportation miles. Organic eliminates the high energy costs of pesticides and fertilizers. Seasonal foods do not need greenhouses or long periods of refrigeration. And the food chain matters, carbon-wise: the CO2 impact of a pound of beef can be 250 times as great as that of a pound of carrots.
