In his tenth book, Ashworth urges ecologists to concede that economics is as natural as an old-growth forest and ought to be utilized, not despised. His tone of mild admonition begins with a cautionary tale: the Anasazi's abandonment of their Mesa Verde complex in Colorado. Ashworth presents the Anasazi case as a microcosmic lesson in the costs of overusing one's local resources, which immediately interests the readers and brings them toward the larger lesson he hopes to instill. Ashworth is a supple stylist who injects his facts, anecdotes, and assertions in a constantly enlivening manner. His unreserved empathy for the environmental cause may not convert his readers, for he challenges such staunch beliefs as "buying green" or imposing more regulation begets a better ecology. What they will appreciate and ponder, though, is the force of his explanations that digesting a few economic notions serves their goals better than the moralistic rejection of economic growth--a great way to sugar the pill. This could shoulder its way among the green classics, so libraries beware.
