Reading this book is kind of humbling. Industrial agriculture produces plentiful calories, given its inputs of fossil fuels, water, soil, weed killers, patented seeds and sun. It makes possible the world we got used to and on balance like. It presents easy, unhealthy choices as well. Yet there's no going back to where farming was 200 years ago. Looks like we'd do better to eat less meat and change how our meat is produced.
