Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
A manifesto for a radically different philosophy and practice of manufacture and environmentalism "Reduce, reuse, recycle" urge environmentalists; in other words, do more with less in order to minimize damage. But as this provocative, visionary book argues, this approach perpetuates a one-way, "cradle to grave" manufacturing model that dates to the Industrial Revolution and casts off as much as 90 percent of the materials it uses as waste, much of it toxic. Why not challenge the notion that human industry must inevitably damage the natural world? In fact, why not take nature itself as our model? A tree produces thousands of blossoms in order to create another tree, yet we do not consider its abundance wasteful but safe, beautiful, and highly effective; hence, "waste equals food" is the first principle the book sets forth. Products might be designed so that, after their useful life, they provide nourishment for something new-either as "biological nutrients" that safely re-enter the environment or as "technical nutrients" that circulate within closed-loop industrial cycles, without being "downcycled" into low-grade uses (as most "recyclables" now are). Elaborating their principles from experience (re)designing everything from carpeting to corporate campuses, William McDonough and Michael Braungart make an exciting and viable case for change.

Book Description
When seven-year-old Dave Lowell was camped out at his father’s mine in the hills of southern Arizona in 1935, he knew he had found his calling. “Life couldn’t get any better than this,” he recalls. “I didn’t know what science was, but wisps of scientific thought were already working into my plan.” So began the legendary career of the engineer, geologist, explorer, and international businessman whose life is recounted in his own words in this captivating book. An Arizona native with family roots in territorial times, Lowell grew from modest beginnings on a ranch near Nogales to become a major world figure in the fields of minerals, mining, and economic geology. He has personally discovered more copper than anyone in history and has developed multibillion-dollar gold and copper mines that have changed the economies of nations. And although he has consulted for corporations in the field of mining, he has largely operated as an independent agent and explorer, the architect of his own path and success. His life’s story unfolds in four stages: his early education in his field, on-the-job learning at sites in the United States and Mexico, development of exploration strategies, and finally, the launch of his own enterprises and companies. Recurring themes in Lowell’s life include the strict personal, ethical, and tactical policies he requires of his colleagues; his devotion to his family; and his distaste for being away from the field in a corporate office, even to this day. The magnitude of Lowell’s overall success is evident in his list of mine discoveries, as well as in his scientific achievements and the enormous respect his friends and colleagues have had for him throughout his lengthy career, which he continues to zealously pursue.

Book Description
Phosphorus in Environmental Technology: Principles and Applications, provides a definitive and detailed presentation of state-of-the-art knowledge on the environmental behaviour of phosphorus and its applications to the treatment of waters and soils. Special attention is given to phosphorus removal for recovery technologies, a concept that has emerged over the past 5-6 years. The book features an all-encompassing approach: the fundamental science of phosphorus (chemistry, geochemistry, mineralogy, biology), key aspects of its environmental behaviour and mobility, industrial applications (treatment, removal, recovery) and the principles behind such applications, novel biotechnologies and, importantly, it also addresses socio-economic issues which often influence implementation and the ultimate success of any new technology. A detailed subject index helps the reader to find their way through the different scientific and technological aspects covered, making it an invaluable reference work for students, professionals and consultants dealing with phosphorus-related environmental technologies. State-of-the-art knowledge on the behaviour of phosphorus and its applications to environmental science and technology. Covers all aspects of phosphorus in the environment, engineered and biological systems; an interdisciplinary text.

Book Description
Since its inception, anthropology's authority has been based on the assumption that it is a unified discipline emanating from the West. In an age of heightened globalization, anthropologists have failed to discuss consistently the current status of their practice and its mutations across the globe. World Anthropologies is the first book to provoke this conversation from various regions of the world in order to assess the diversity of relations between regional or national anthropologies and a contested, power-laden Western discourse. Can a planetary anthropology cope with both the 'provincial cosmopolitanism' of alternative anthropologies and the 'metropolitan provincialism' of hegemonic schools? How might the resulting 'world anthropologies' challenge the current panorama in which certain allegedly national anthropological traditions have more paradigmatic weight - and hence more power - than others? Critically examining the international dissemination of anthropology within and across national power fields, contributors address these questions and provide the outline for a veritable world anthropologies project.
