This is a book about simplicity - not destitution, not parsimoniousness, not self-denial - but the restoration of wealth in the midst of an affluence in which the author believes we are starving the spirit. It has to do with having less and enjoying more - enjoying time to do the work you love, enjoying time to spend with your family, enjoying time to pursue creative projects, enjoying time for good eating, enjoying time just to be. Another theme of the book concerns the future of our home, the Earth. Our grandchildren will inherit an Earth with less than 20 per cent of its original forests still intact, with most of the readily available freshwater already spoken for, with most of the wetlands and reef systems either destroyed or degraded. Sooner or later, the author believes, a more frugal lifestyle will not only be desirable - it will become an imperative.
