When searching for books on sustainability its easy to find books heavy on opinion while practical application books are few and far between. This is one of the latter, a very accessible project oriented guide to making changes in the way we act. This book is filled with small scale systems that provides a great starting point for people who want to make actual change in their lives and not just read environmental theory, as great as that may be. The real gem in this book is the well organized bibliography, as many of the projects I would feel more comfortable completing with more detailed background knowledge of the processes going on, which is of course beyond the scope of this publication. Not to downplay the information contained in the book itself, which is awesome.The key to making change is to make small changes, baby steps, slowly building your new lifestyle. I started with the vermicompostig, which is pretty tame, and moved on from there. Good Luck!
