"Brad claims US agriculture uses about 400 gasoline-gallon equivalents per American per year (if anyone can source this figure I would be very grateful). So that is 1.1 gallons a day to produce the 2700 calories that form the average American's diet or 10 calories of fossil fuel for each calorie of food consumed. That is right: 10 fuel calories for each food calorie! It is a shocking statistic isn't it?"
