PRAISE FOR THE BIG RATCHET "[A] lucid and intelligent book... There is something satisfyingly stark and elemental about DeFries' focus on food, which, she notes, is 'our most fundamental connection with nature'."--Financial Times "Engaging and optimistic." --Wall Street Journal "DeFries unpicks the historical patterns to parse the uneasy equation of people and food -- our most powerful link with nature." --Nature "At its heart, The Big Ratchet is a food book, deserving a place on the shelf alongside work by the likes of Michael Pollan, Mark Bittman, and Marion Nestle that criticize our modern system of industrial agriculture." --Johns Hopkins Magazine "The Big Ratchet is a well-researched and highly readable account of how we came to be a 'world dominating urban species', and the opportunities and threats we will face in feeding a world of 9 billion people with only a small minority living in rural areas. For those who have deep concerns about our ability to meet future food needs, this book provides at least some reassurance that we have done it before." --Nature Geoscience "[The Big Ratchet] is a fast-moving and information-packed history of human appetites... DeFries does environmentalism a favor by presenting this history as a dialectic that never ends." --Orion "[A]n interesting and timely thesis... This is an environmental history, chockablock with examples from the past that might guide us in the future." --Toronto Star (Canada) "[E]ye-opening and eminently readable." --Columbia College Today "Ruth DeFries has written a brilliant book that starts with the origin of Earth and life on our planet, and goes through thousands of years of ecological history and one natural crisis after another... DeFries has a nuanced and sophisticated view of human history... [The Big Ratchet] is a beautifully written book that is unique in combining wisdom, scientific discovery, and story-telling." --Cool Green Science "[A] fair, thorough look at how modern agriculture changed the world." --getAbstract "An admirable history of human ingenuity that does not claim it will overcome such looming crises as overpopulation and global warming." --Kirkus Reviews "DeFries places her faith in human creativity as a primary means to our survival, an appealing point of view for the hopeful but concerned reader." --PublishersWeekly "Timely... Clearly demonstrates the role of science in converting calamities into opportunities. The Big Ratchet provides a message of hope in the midst of the sea of despair we see in the areas of sustainable development and environmental protection. Ruth DeFries has rendered an invaluable service." --M. S. Swaminathan, Founder and Chairman, M. S. Swaminathan Research Foundation "A page turner and an eye opener, clearly written and well told. If you are alive today, especially if you live in a city, this is the story of how you got here and why you eat what you eat. Defries deftly guides us through our species' unending quest to squeeze more food out of the earth, introducing us along the way to buffalo bone pickers, ancient plant breeders, guano wars, the extinction of the Rocky Mountain Locust, medieval human poop tradesmen, Arctic "doomsday" seed vaults and the Nobel Prizes awarded to the inventors of DDT and trans fats. A fascinating history of human innovation." --Emma Marris, author of Rambunctious Garden "Is there a tale more astonishing and improbable than the human story? Lurching between triumph and catastrophe, humankind has transformed itself from a run-of-the-mill forager on the African savanna into a species that dominates every corner of the planet. Now, as our numbers surpass 7 billion, Ruth DeFries shows how our remarkable past can serve as a guide to thinking about our uncertain future. Neither a hymn to optimism nor an invocation of catastrophe, The Big Ratchet is an essential account of how we got to be where we are." --Charles C. Mann, author of 1491 "[The Big Ratchet] survey[s] the technological innovations that transformed humans from nomadic hunter-gatherers threatened with starvation into farmers and then into urban-dwelling specialists whose sustenance is usually produced far away by a relative few... DeFries sums up the cycle in the pithy catchphrase 'ratchet, hatchet, pivot.'" --Science News
