I recently purchased this book. The author's thought is that lots of people want to live green but don't know how, where to start, or don't want to do all the research. So, he did it for us and lays out the basics of what products to buy, what companies go the extra mile to "go green" with their products, and little tips for your every day life. It is more of a reference book when you are deciding to buy something (ie. a toothbrush, a car, shoes, stocks, etc.) than a read through.
