Enough - Staying Human in an Engineered Age. In his first book, "The End of Nature" Bill McKibben demonstrated that humanity had begun to irrevocably alter and endanger our environment on a global scale. Now he turns his eye to an array of technologies that could change our relationships, not just with the rest of nature but with ourselves. As he explores the frontiers of genetic engineering, robotics, and nanotechnology - all of which we are approaching with astonishing speed - he shows that each threatens to take us to a point of no return. We now understand, in Michael Pollan's words, "on a moral and existential threshold - or cliff". McKibben offers a celebration of what it means to be human and a warning that we risk the loss of all meaning if we step across that threshold. Acclaimed for its passion and insight, this wise and eloquent book argues that we cannot grow forever in reach and power - that we must at last learn how to say, "Enough". Bill McKibben is the author of eight books, including "The End of Nature and The Age of Missing Information." He is a regular contributor to "Harper's", "The Atlantic", and "The New York Review of Books", and is a scholar-in-residence at Middlebury College. He lives with his wife, the writer Sue Halpern, in the mountains surrounding Lake Champlain. Soft cover, 271 pages, 5" x 8". To Order By Phone Call Toll Free: 866-596-9982
