“Bill McKibben has produced a book that is both a sequel and an equal to his brilliant The End of Nature. Enough is an ambitious and important book.” —Los Angeles Times Book Review

“Without question, this is one of the most important books of the year. McKibben deserves to be read, to be discussed, to be heard.” —San Diego Union-Tribune

“[A] brave and luminous book . . . Bill McKibben understands genetics--but he knows poetry, too.” —David Gelernter, Wired

“Bill McKibben has done a top-notch job of researching and writing about one of the most important topics of the current age. Enough is an important book and needs to be read by everyone with an interest in keeping the human future human.” —The Weekly Standard

“Fiercely important . . . the most thought-provoking piece of non-fiction I've read in a long time.” —The Globe and Mail (Toronto)

“In this wise, well-researched, and important book, Bill McKibben addresses the burning philosophical question of the new century, and the one that counts for the long haul: how to control the technoscientific juggernaut before it dehumanizes our species.” —E. O. Wilson, author of The Future of Life

“In Enough, McKibben shines his powerful light on another momentous change that is upon us: the ability to re-engineer ourselves and therefore the very meaning of human identity. If he is right, then humankind stands on a moral and existential threshold--or cliff. We would do well as a society to weigh his bracing argument before taking another step.” —Michael Pollan, author of The Botany of Desire
