A stunningly original, lushly illustrated vision for a Green Utopia, published on the 500th anniversary of the original Big Idea. Five hundred years ago a powerful new word was unleashed upon the world when Thomas More published his book Utopia, about an island paradise far away from his troubled land. It was an instant hit, and the literati across Europe couldn't get enough of its blend of social fantasy with a deep desire for a better world. Five hundred years later, Ecotopia 2121 once again harnesses the power of the utopian imagination to confront our current problems, among them climate change, and offer a radical, alternative vision for the future of our troubled planet. Depicting one hundred cities around the globe—from New York to San Francisco, London, Tokyo, Sydney, Rio de Janeiro, Mexico City, Beijing, Vienna, Singapore, Cape Town, Abu Dhabi, and Mumbai—Alan Marshall imagines how each may survive and prosper. A striking, full-color scenario painting illustrates each city. The chapters tell how each community has found either a social or technological innovation to solve today's crises. Fifteen American cities are covered. Around the world, urban planners like to tailor scenarios for the year 2020, to take advantage of the metaphor of 20-20 vision. In Ecotopia 2121, the vision may be fuzzy, but its sharp insights, captivating illustrations, and playful storytelling will keep readers coming back again and again.
