Because of the scientific terminology and the interlinked data amassed bit by bit, this is not an easy read for narrator or lay listener. But it's a fascinating book, and Grupper handles it well. Grupper's careful narration brings to life Weisman's judicious organization, unambiguous grammatical structure and vivid descriptions of what would become of land, sea, fish, flora and fauna should humans disappear from the face of the earth. Weisman explains the earth's capacity for self-healing. Unchecked by human intervention, a city like New York would flood within days, its buildings and infrastructure would collapse, and soon the city would revert to its original ecosystem. But the message of the book is our legacy to the universe: “Every bit of plastic manufactured over the last 80 years or so still remains somewhere in the environment.” Weisman and Grupper convert abstract environmental concepts into concrete ideas. Broadly and meticulously researched, finely interwoven journalism and imaginative projection, the book is an utterly convincing call to action. Simultaneous release with the St. Martin's/Dunne hardcover (Reviews, May 14). (July)
