With easy-to-understand terminology and a mountain of research, Toronto author Homer-Dixon (The Ingenuity Gap) faces down imminent, unavoidable and catastrophic threats to modern civilization, keeping a wary eye on mankind's chances to adapt. Methodically illustrating how the modern world is doomed to suffer a large-scale breakdown, Homer-Dixon enumerates the "tectonic stresses" on civilization-population growth disparities, energy scarcity, environmental damage, and economic instabilities-and the "multipliers"-increasing global connectivity and small groups' ability to enact destruction-that help propel them. Woven throughout are well-illustrated comparisons between the current state of industrialized nations-especially the U.S.-with the unsustainable complexities, and subsequent downfall, of the Roman Empire. With each page, humanity's situation seems more dire, but Homer-Dixon argues that the force of "catagenesis"-the "commonplace occurrence of renewal through breakdown"-means that good will come from the collapse of civilization as we know it. Unfortunately, he offers few practical suggestions as to how we can prepare for civilization's inevitable failure, and little evidence on which to hang hope. As a result, the book takes on a tone of doomsday prophecy directly at odds with its title. Where Homer-Dixon succeeds admirably is in explaining exactly why modern stresses are so worrisome and the outcomes that neglect could cause.

Book Description
Environmental disasters. Terrorist wars. Energy scarcity. Economic failure. Is this the world's inevitable fate, a downward spiral that ultimately spells the collapse of societies? Perhaps, says acclaimed author Thomas Homer-Dixon - or perhaps these crises can actually lead to renewal for ourselves and planet earth.

The Upside of Down takes the reader on a mind-stretching tour of societies' management, or mismanagement, of disasters over time. From the demise of ancient Rome to contemporary climate change, this spellbinding book analyzes what happens when multiple crises compound to cause what the author calls "synchronous failure." But, crisis doesn't have to mean total global calamity. Through catagenesis, or creative, bold reform in the wake of breakdown, it is possible to reinvent our future.

Drawing on the worlds of archeology, poetry, politics, science, and economics, The Upside of Down is certain to provoke controversy and stir imaginations across the globe. The author's wide-ranging expertise makes his insights and proposals particularly acute, as people of all nations try to grapple with how we can survive tomorrow's inevitable shocks to our global system. There is no guarantee of success, but there are ways to begin thinking about a better world, and The Upside of Down is the ideal place to start thinking.
