Graham's book opened my eyes to what is wrong with our agricultural system: A strong reliance on grain, fertilisers and oil has meant that the majority of our food is expensive, tastes like cardboard and contains few nutrients. By simply changing to a different farming system we can solve problems such as the food crisis, the greenhouse effect and ill health. I'll certainly be eating grass fed from now. Once you've read this book you'll want to as well. Graham's style of writing means that even someone with no knowledge of food science and farming (like myself) can understand. The nice bitesize chapters make easy and enjoyable reading.
