Enough: Staying Human in an Engineered Age

From the bestselling author of The End of Nature comes a passionate plea to limit the technologies that could change the very definition of who we areWe are on the verge of crossing the line from born to made, from created to built. Sometime in the next few years, a scientist will reprogram a human egg or sperm cell, spawning a genetic change that could be passed down into eternity. We are sleepwalking toward the future, argues Bill McKibben, and it’s time to open our eyes.In The End of Nature, nearly fifteen years ago, 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 relationship not with the rest of nature but with ourselves.
