For 290,000 years, we managed to meet that need as hunter-gatherers, a state in which Manning believes we were at our most human: at our smartest, strongest, most sensually alive. But our reliance on food made a secure supply deeply attractive, and eventually we embarked upon the agricultural experiment that has been the history of our past 10,000 years.The evolutionary road is littered with failed experiments, however, and Manning suggests that agriculture as we have practiced it runs against both our grain and nature's. Drawing on the work of anthropologists, biologists, archaeologists, and philosophers, along with his own travels, he argues that not only our ecological ills-overpopulation, erosion, pollution-but our social and emotional malaise are rooted in the devil's bargain we made in our not-so-distant past. And he offers personal, achievable ways we might re-contour the path we have taken to resurrect what is most sustainable and sustaining in our own nature and the planet's.

    Pope Francis calls the Church and the world to acknowledge the urgency of our environmental challenges and to join him in embarking on a new path. This encyclical is written with both hope and resolve, looking to our common future with candor and humility.

    To the philosophical the  earth is eternal, while the human race -- presumptive  keeper of the world's history -- is a mere speck  in the rich stream of life. It is known that  nothing upon Earth is forever; geography, climate, and  plant and animal life are all subject to radical  change. On five occasions in the past, catastrophic  natural events have caused mass extinctions on  Earth. But today humans stand alone, in dubious  distinction, among Earth's species: Homo  Sapiens possesses the ability to destroy  entire species at will, to trigger the sixth  extinction in the history of life. In The Sixth  Extinction, Richard Leakey and Roger Lewin  consider how the grand sprawl of human life is  inexorably wreaking havoc around the world. The  authors of Origins and  Origins Reconsidered, unimpeachable  authorities on the human fossil record, turn their  attention to the most uncharted anthropological territory  of all: the future, and man's role in defining it.  According to Leakey and Lewin, man and his  surrounding species are end products of history and  chance. Now, however, humans have the unique  opportunity to recognize their influence on the global  ecosystem, and consciously steer the outcome in order  to avoid triggering an unimaginable upheaval.From the Hardcover edition.

    Is it time to abandon the concept altogether, or can we find an accurate way to measure sustainability? If so, how can we achieve it? And if not, how can we best prepare for the coming ecological decline? In the latest edition of Worldwatch Institute’s State of the World series, scientists, policy experts, and thought leaders tackle these questions, attempting to restore meaning to sustainability as more than just a marketing tool. In State of the World 2013: Is Sustainability Still Possible?, experts define clear sustainability metrics and examine various policies and perspectives, including geoengineering, corporate transformation, and changes in agricultural policy, that could put us on the path to prosperity without diminishing the well-being of future generations. If these approaches fall short, the final chapters explore ways to prepare for drastic environmental change and resource depletion, such as strengthening democracy and societal resilience, protecting cultural heritage, and dealing with increased conflict and migration flows.State of the World 2013 cuts through the rhetoric surrounding sustainability, offering a broad and realistic look at how close we are to fulfilling it today and which practices and policies will steer us in the right direction. This book will be especially useful for policymakers, environmental nonprofits, and students of environmental studies, sustainability, or economics.
