This book by a father-and-son team doesn’t wallow in all-too-true tales of resource depletion; it jumps in with real-life self-sufficiency solutions that have perfected on their Newhouse Farm in Cornwall, England. This haven of ecologically friendly practices has been the focus of BBC Two’s popular series “It’s Not Easy Being Green”, a title at least somewhat belied by the simplicity of the practical changes suggested in Self Sufficiency for The 21st Century. (Hand-selling tip: It’s important to realize that low impact living isn’t generally a one-jump leap. The incremental changes recommended in this book can help people take their first major steps in that direction.)
