Peter Gleick on the History and Uncertain Future of the World’s Water

At a United Nations water conference in March, amid increasing global water conflicts and climate crises, U.N. Secretary-General António Guterres sounded an urgent alarm. “All of humanity’s hopes for the future depend, in some way, on charting a new course to sustainably manage and conserve water,” he said. But what would a new course look like? Renowned water expert and scientist  Peter Gleick seeks to answer that question in his latest book “The Three Ages of Water”. The book explores the complex relationship between humans and water throughout history, from ancient civilizations to the modern, scientific “Second Age of Water” when we “learned to manipulate the natural hydrologic cycle” but also did great harm to the planet. We’ll talk with Gleick about his call for a revolutionary “Third Age” of responsible water stewardship.
