Dirt, soil, call it what you want—it's everywhere we go. It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

"From this gritty and compelling state-of-our-earth report comes the inescapable truth that we are nothing if not dirty-minded. A brilliant and essential book." Roger Swain, science editor of Horticulture magazine
"The relationship between soils and societies has been crucial for humankind for 10,000 years. David Montgomery brings a geomorphologist's eye and a world-historical vision to the subject, showing why it demands our attention." J.R. McNeill, author of Something New Under the Sun
In our cyber-charged age, it’s easy to forget that all six billion of us stand on the thin skin of the earth. Humanity is agriculture and agriculture is soil, just as it has been for 10,000 years.

Buchbeschreibung University Press Group Ltd Apr 2012, 2012. Taschenbuch. Buchzustand: Neu. Neuware - In a fast-paced, accessible yet sweeping synthesis, renowned geologist and published trade author David Montgomery examines human history through the lens of agriculture and how increasing intensification of farming undercut the foundation civilizations around the world whose use of soil outstripped the natural supply. Drawing from archaeology, geology, soil science, and history, Montgomery shows that the life span of civilizations can be determined from the way they treat their land. Dirt is our most under-appreciated yet most essential resource. Soil erodes much more quickly than it forms, but erosion is inevitable and is hastened by our widespread agricultural practices and other abuses. Each year, the world now loses some 24 billion tons of topsoil. Montgomery describes how ancient societies - the Greeks, Romans, Maya, etc. - repeatedly exhausted their land at a pace set by their technological sophistication and hastened their downfall and created populations of refugees. Societies that run out of dirt run out of options to survive, but Montgomery holds out hope that recent interest in no-till and organic agriculture, practices that protect soil and water, will allow farsighted societies to follow a more sustainable path and cling to the ground beneath them.
