Enriching the Earth

Enriching the Earth PDF Author: Vaclav Smil
Publisher: MIT Press
ISBN: 0262693135
Category : Science
Languages : en
Pages : 359

Book Description
Dr. Smil is the world's authority on nitrogenous fertilizer. The industrial synthesis of ammonia from nitrogen and hydrogen has been of greater fundamental importance to the modern world than the invention of the airplane, nuclear energy, space flight, or television. The expansion of the world's population from 1.6 billion people in 1900 to today's six billion would not have been possible without the synthesis of ammonia. In Enriching the Earth, Vaclav Smil begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts to expand natural nitrogen flows through mineral and synthetic fertilizers. The core of the book is a detailed narrative of the discovery of ammonia synthesis by Fritz Haber—a discovery scientists had sought for over one hundred years—and its commercialization by Carl Bosch and the chemical company BASF. Smil also examines the emergence of the large-scale nitrogen fertilizer industry and analyzes the extent of global dependence on the Haber-Bosch process and its biospheric consequences. Finally, it looks at the role of nitrogen in civilization and, in a sad coda, describes the lives of Fritz Haber and Carl Bosch after the discovery of ammonia synthesis.

Falling to Earth

Falling to Earth PDF Author: Kate Southwood
Publisher: Europa Editions
ISBN: 1609451104
Category : Fiction
Languages : en
Pages : 220

Book Description
A “poignant [and] powerful” novel about a 1920s Midwestern community in the aftermath of a devastating tornado (The New Yorker). In March 1925, the worst tornado in the nation’s history will descend without warning on the small town of Marah, Illinois. By nightfall, hundreds will be homeless and hundreds more will lie in the streets, dead or grievously injured. Only one man, Paul Graves, will still have everything he started the day with—his family, his home, and his business, all miraculously intact. This “absolutely gorgeous” novel follows Paul Graves and his young family in the year after the storm as they struggle to comprehend their own fate and that of their devastated town (The New York Times). They watch helplessly as Marah tries to resurrect itself from the ruins and as their friends and neighbors begin to wonder how one family, and only one, could be exempt from terrible misfortune. As the town begins to recover, the family miscalculates the growing resentment and hostility around them with tragic results, in an “extraordinarily moving” portrayal of survivor’s guilt and the frenzy of bereavement following a disaster (Financial Times). “All the big themes are here—chance, fate, loyalty, revenge, guilt, jealousy . . . Inspired by actual events surrounding the 1925 Tri-State tornado, the worst in U.S. history, Southwood’s poignantly penetrating examination of the psychic cost of survival is breathtaking in its depth of understanding.” —Booklist (starred review) “What’s most exciting about Southwood’s debut is her prose, which is reminiscent of Willa Cather’s in its ability to condense the large, ineffable melancholy of the plains into razor-sharp images.” —The Daily Beast

Harvesting the Biosphere

Harvesting the Biosphere PDF Author: Vaclav Smil
Publisher: MIT Press
ISBN: 026201856X
Category : Science
Languages : en
Pages : 317

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.
