The most vital project of the twenty-first century is a shift from our unsustainable way of life to a sustainable one--a great lateral leap from a track headed for economic and ecological disaster to one bound for renewed prosperity. In The Leap, Chris Turner presents a field guide to making that jump, drawing on recent breakthroughs in state-of-the-art renewable energy, cleantech and urban design. From the solar towers of sunny Spain to the bike paths and pedestrianized avenues of the world's most livable city--Copenhagen, Denmark--to the nascent "green-collar" economies rejuvenating the former East Germany and the American Rust Belt, he paints a vivid portrait of a new, sustainable world order already up and running. In his 2007 book, The Geography of Hope, Chris Turner wrote about an emerging world of cleantech possibility. In The Leap, he looks beyond hope to uncover the winners and losers of the future we can no longer deny.
