Author Alan Weisman shares insights from his latest book, Countdown: Our Last, Best Hope for a Future on Earth? Can we feed a human population headed toward 11 billion, and still leave enough for other species on which our own survival may depend? Will technological leaps like genetically enhanced photosynthesis or lab-grown meat actually help us avert disaster? In his latest book, Countdown: Our Last, Best Hope for a Future on Earth?, author Alan Weisman considers whether and how people can sustainably thrive without crashing the global ecosystem. Traveling to 21 countries for insights from a broad swath of cultures, ecosystems, scientists, food specialists, and religious leaders, Weisman pursues the concept of a future balance between us and the world.
