Biosphere 2000


Book Description




The Earth's Biosphere


Book Description

A comprehensive overview of Earth's biosphere, written with scientific rigor and essay-like flair. In his latest book, Vaclav Smil tells the story of the Earth's biosphere from its origins to its near and long-term future. He explains the workings of its parts and what is known about their interactions. With essay-like flair, he examines the biosphere's physics, chemistry, biology, geology, oceanography, energy, climatology, and ecology, as well as the changes caused by human activity. He provides both the basics of the story and surprising asides illustrating critical but often neglected aspects of biospheric complexity. Smil begins with a history of the modern idea of the biosphere, focusing on the development of the concept by Russian scientist Vladimir Vernadsky. He explores the probability of life elsewhere in the universe, life's evolution and metabolism, and the biosphere's extent, mass, productivity, and grand-scale organization. Smil offers fresh approaches to such well-known phenomena as solar radiation and plate tectonics and introduces lesser-known topics such as the quarter-power scaling of animal and plant metabolism across body sizes and metabolic pathways. He also examines two sets of fundamental relationships that have profoundly influenced the evolution of life and the persistence of the biosphere: symbiosis and the role of life's complexity as a determinant of biomass productivity and resilience. And he voices concern about the future course of human-caused global environmental change, which could compromise the biosphere's integrity and threaten the survival of modern civilization.




Energy 2000


Book Description

Originally published in 1986, this book takes an inter-disciplinary approach to the options for energy in the future. Written in a clear, easy-to-read style, it proposes that future solutions should not be based solely on cost, given our plentiful energy resources, but on ecological, human and ethical considerations. The book features a quantittive review of energy sources, supported by numerous figures and tables, that includes such long-term solutions as nuclear fission and solar energy. The book allows engineers and students to easily weigh the pros and cons of all energy options to realistically plan for the future.




Harvesting the Biosphere


Book Description

An interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistoric hunting to modern energy production. The biosphere—the Earth's thin layer of life—dates from nearly four billion years ago, when the first simple organisms appeared. Many species have exerted enormous influence on the biosphere's character and productivity, but none has transformed the Earth in so many ways and on such a scale as Homo sapiens. In Harvesting the Biosphere, Vaclav Smil offers an interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistory to the present day. Smil examines all harvests—from prehistoric man's hunting of megafauna to modern crop production—and all uses of harvested biomass, including energy, food, and raw materials. Without harvesting of the biomass, Smil points out, there would be no story of human evolution and advancing civilization; but at the same time, the increasing extent and intensity of present-day biomass harvests are changing the very foundations of civilization's well-being. In his detailed and comprehensive account, Smil presents the best possible quantifications of past and current global losses in order to assess the evolution and extent of biomass harvests. Drawing on the latest work in disciplines ranging from anthropology to environmental science, Smil offers a valuable long-term, planet-wide perspective on human-caused environmental change.

Selected Studies in Biodiversity


Book Description

The present book offers an overall up-to-date overview of the biological diversity, comprising many interesting chapters focussing on the different aspects of biodiversity. Most of the chapters include findings of investigations and observations on biodiversity, whilst a few are based on statistically and theoretically derived information. The book produced sufficient information on the occurrence and distribution of many plant and animal species or groups of organisms with environmental estimates from a wide variety of interesting terrestrial and aquatic habitats. With 18 interesting and elaborately prepared chapters, the present book would definitely be an ideal source of scientific information to the advanced students, junior researchers, scientists and a portion of the public involved in ecology and other research areas involving biodiversity studies. It will also help to the development of the growing awareness of the close linkage between the conversation of biodiversity and economic development.




The Biosphere and the Bioregion


Book Description

Bioregionalism asks us to reimagine ourselves and the places where we live in ecological terms and to harmonize human activities with the natural systems that sustain life. As one of the originators of the concept of bioregionalism, Peter Berg (1937-2011) is a founding figure of contemporary environmental thought. The Biosphere and the Bioregion: Essential Writings of Peter Berg introduces readers to the biospheric vision and post-environmental genius of Berg. From books and essays to published interviews, this selection of writings represents Berg's bioregional vision and its global, local, urban, and rural applications. The Biosphere and the Bioregion provides a highly accessible introduction to bioregional philosophy, making Berg's paradigm available as a guiding vision and practical "greenprint" for the twenty-first century. This valuable compilation lays the groundwork for future research by offering the first-ever comprehensive bibliography of Berg's publications and should be of interest to students and scholars in the interdisciplinary fields of environmental humanities, environment and sustainability studies, as well as political ecology, environmental sociology and anthropology.

Biodiversity II


Book Description

"The book before you...carries the urgent warning that we are rapidly altering and destroying the environments that have fostered the diversity of life forms for more than a billion years." With those words, Edward O. Wilson opened the landmark volume Biodiversity (National Academy Press, 1988). Despite this and other such alarms, species continue to vanish at a rapid rate, taking with them their genetic legacy and potential benefits. Many disappear before they can even be identified. Biodiversity II is a renewed call for urgency. This volume updates readers on how much we already know and how much remains to be identified scientifically. It explores new strategies for quantifying, understanding, and protecting biodiversity, including: New approaches to the integration of electronic data, including a proposal for a U.S. National Biodiversity Information Center. Application of techniques developed in the human genome project to species identification and classification. The Gap Analysis Program of the National Biological Survey, which uses layered satellite, climatic, and biological data to assess distribution and better manage biodiversity. The significant contribution of museum collections to identifying and categorizing species, which is essential for understanding ecological function and for targeting organisms and regions at risk. The book describes our growing understanding of how megacenters of diversity (e.g., rainforest insects, coral reefs) are formed, maintained, and lost; what can be learned from mounting bird extinctions; and how conservation efforts for neotropical primates have fared. It also explores ecosystem restoration, sustainable development, and agricultural impact. Biodiversity II reinforces the idea that the conservation of our biological resources is within reach as long as we pool resources; better coordinate the efforts of existing institutionsâ€"museums, universities, and government agenciesâ€"already dedicated to this goal; and enhance support for research, collections, and training. This volume will be important to environmentalists, biologists, ecologists, educators, students, and concerned individuals.
