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.

Meteorologies of Modernity explores the ways in which literature reflects and participates in discourses on weather and climate – historically as well as at our contemporary moment. Literature contains a huge meteorological archive built throughout the centuries. The essays collected in this volume therefore ask to what extent literature can bring the vastness and complexity of climate change into view, how literature offers ways to think through the challenges of the Anthropocene both culturally, historically, and aesthetically, and, last but not least, how it helps us to conceptualize a radically new understanding of what it means to be human. The thirteen contributions from literary and cultural studies address weather and climate discourses from a variety of conceptual angles and cover a broad range of historical and geographical contexts. Topics include representations of tropical climates in Shakespeare, the close yet tense relationship between literature and the rising discipline of meteorology in the nineteenth century, allegories of climate change in postcolonial literature, and climate catastrophes in the contemporary clifi novel. By employing a historicizing and comparative approach, the volume addresses the need for studying representations of climate and climate change in an interdisciplinary, transnational and transhistorical framework, overcoming traditional disciplinary boundaries and creating new collectives of theory and criticism that are essential when debating the Anthropocene.

Governing Technology in the Quest for Sustainability on Earth explores how human technologies can be managed to ensure the long-term sustainability of our species and of other life forms with which we share this world. It analyses human impact, the discourses of environmentalism and issues of economics, history and science. As these variables are complex, drawing on issues from the social, physical and life sciences as well as the humanities, Dain Bolwell uses an interdisciplinary approach to investigate these concepts and their related public policies. Exploring three major existing and emerging technologies – chemical herbicides, nuclear-electric power generation, and robotics and artificial intelligence – the book demonstrates the multifaceted and complicated nature of the grand challenges we face and draws out the measures required to effect sustainability in the wider political sphere. Exploring how we can govern technology most effectively to ensure a long term and sustainable future, this book will be of great interest to students and researchers of environmental studies, science and technology and environmental law and policy.

Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.
