Bookchin wrote Our Synthetic Environment under the pseudonym Lewis Herber. This was one of the first books of the modern period in which an author espoused an ecological and environmentalist worldview. It predates Silent Spring (1962) by Rachel Carson, a more widely known book on the same topic widely credited as starting the environmental movement. "At the time of its publication, Our Synthetic Environment was the most comprehensive and enlightened book on the environmental crisis. Many other books on this topic have been published since, but none, I believe, as comprehensive." –Rene Dubos-Print ed.
