Although the book does provide some useful food for thought, I was really let down when I read the author's recommendation of clothing made from bamboo fabric. Her explanation was that because bamboo is fast to grow and requires less water than other fabric sources, it is a relatively environmentally-friendly fabric. However, a huge amount of toxic chemical processing is used to turn bamboo into that super-soft fabric, and half of those chemicals are dumped directly into the environment after processing. Bamboo rayon is one of the LEAST environmentally-friendly fabrics on the market. Save the bamboo for flooring and other hard products!
I bought my copy used and have already jettisoned it, so I am not sure if this recommendation is made in the newer editions, but the oldest edition was made in 2007, when the problems with bamboo rayon were already known. Reading it caused me to lose trust in the rest of the book, making me wonder how thoroughly researched it really is. If I cannot trust that the other recommendations in the book are solid without independently researching them myself, the book has lost most of its value, since I would have to research the different options regardless.
