In Jared Diamond’s follow-up to the Pulitzer-Prize winning Guns, Germs and Steel , the author explores how climate change, the population explosion and political discord create the conditions for the collapse of civilization Environmental damage, climate change, globalization, rapid population growth, and unwise political choices were all factors in the demise of societies around the world, but some found solutions and persisted. As in Guns, Germs, and Steel , Diamond traces the fundamental pattern of catastrophe, and weaves an all-encompassing global thesis through a series of fascinating historical-cultural narratives. Collapse moves from the Polynesian cultures on Easter Island to the flourishing American civilizations of the Anasazi and the Maya and finally to the doomed Viking colony on Greenland. Similar problems face us today and have already brought disaster to Rwanda and Haiti, even as China and Australia are trying to cope in innovative ways. Despite our own society’s apparently inexhaustible wealth and unrivaled political power, ominous warning signs have begun to emerge even in ecologically robust areas like Montana. Brilliant, illuminating, and immensely absorbing, Collapse is destined to take its place as one of the essential books of our time, raising the urgent question: How can our world best avoid committing ecological suicide? "Mr. Diamond...is a lucid writer with an ability to make arcane scientific concepts readiily accesible to the lay reader, and his case studies of failed cultures are never less than compelling." — The New York Times "... Collapse is a magisterial effort packed with insight and written with clarity and enthusiasm." — Businessweek " Guns, Germs, and Steel and Collapse represent one of the most significant projects embarked upon by any intellectual of our generation. They are magnificent books: extraordinary in erudition and originality, compelling in their ability to relate the digitized pandemonium of the present to the hushed agrarian sunrises of the far past. I read both thinking what literature might be like if every author knew so much, wrote so clearly and formed arguments with such care." — Gregg Easterbrook , The New York Times Book Review Jared Diamond is a professor of geography at the University of California, Los Angeles.

PROLOGUE A Tale of Two Farms A few summers ago I visited two dairy farms, Huls Farm and Gardar Farm, which despite being located thousands of miles apart were still remarkably similar in their strengths and vulnerabilities. Both were by far the largest, most prosperous, most technologically advanced farms in their respective districts. In particular, each was centered around a magnificent state-of-the-art barn for sheltering and milking cows. Those structures, both neatly divided into opposite-facing rows of cow stalls, dwarfed all other barns in the district. Both farms let their cows graze outdoors in lush pastures during the summer, produced their own hay to harvest in the late summer for feeding the cows through the winter, and increased their production of summer fodder and winter hay by irrigating their fields. The two farms were similar in area (a few square miles) and in barn size, Huls barn holding somewhat more cows than Gardar barn (200 vs. 165 cows, respectively). The owners of both farms were viewed as leaders of their respective societies. Both owners were deeply religious. Both farms were located in gorgeous natural settings that attract tourists from afar, with backdrops of high snow-capped mountains drained by streams teaming with fish, and sloping down to a famous river (below Huls Farm) or 3ord (below Gardar Farm). Those were the shared strengths of the two farms. As for their shared vulnerabilities, both lay in districts economically marginal for dairying, because their high northern latitudes meant a short summer growing season in which to produce pasture grass and hay. Because the climate was thus suboptimal even in good years, compared to dairy farms at lower latitudes, both farms were susceptible to being harmed by climate change, with drought or cold being the main concerns in the districts of Huls Farm or Gardar Farm respectively. Both districts lay far from population centers to which they could market their products, so that transportation costs and hazards placed them at a competitive disadvantage compared to more centrally located districts. The economies of both far
