Nitrogen Overload by Brian G. Katz Pdf

Finalist for the 2021 PROSE Award for Environmental Science! An integrated approach to understanding and mitigating the problem of excess nitrogen Human activities generate large amounts of excess nitrogen, which has dramatically altered the nitrogen cycle. Reactive forms of nitrogen, especially nitrate and ammonia, are particularly detrimental. Given the magnitude of the problem, there is an urgent need for information on reactive nitrogen and its effective management. Nitrogen Overload: Environmental Degradation, Ramifications, and Economic Costs presents an integrated, multidisciplinary review of alterations to the nitrogen cycle over the past century and the wide-ranging consequences of nitrogen-based pollution, especially to aquatic ecosystems and human health. Volume highlights include: Comprehensive background information on the nitrogen cycle Detailed description of anthropogenic nitrogen sources Review of the environmental, economic, and health impacts of nitrogen pollution Recommendations and strategies for reducing humanity's nitrogen footprint Discussion of national nitrogen footprints and worldwide examples of mitigation policies The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

The End of the Long Summer by Dianne Dumanoski Pdf

For the past twelve thousand years, Earth’s stable climate has allowed human civilization to flourish. But this long benign summer is an anomaly in the Earth’s history and one that is rapidly coming to a close. The radical experiment of our modern industrial civilization is now disrupting our planet’s very metabolism; our future hinges in large part on how Earth responds. Climate change is already bearing down, hitting harder and faster than expected. The greatest danger is not extreme yet discrete weather events, such as Hurricane Katrina or the calamitous wildfires that now plague California, but profound and systemic disruptions on a global scale. Contrary to the pervasive belief that climate change will be a gradual escalator ride into balmier temperatures, the Earth’s climate system has a history of radical shifts–dramatic shocks that could lead to the collapse of social and economic systems. The question is no longer simply how can we stop climate change, but how can we as a civilization survive it. The guiding values of modern culture have become dangerously obsolete in this new era. Yet as renowned environmental journalist Dianne Dumanoski shows, little has been done to avert the crisis or to prepare human societies for a time of growing instability. In a work of astonishing scope, Dumanoski deftly weaves history, science, and culture to show how the fundamental doctrines of modern society have impeded our ability to respond to this crisis and have fostered an economic globalization that is only increasing our vulnerability at this critical time. She exposes the fallacy of banking on a last-minute technological fix as well as the perilous trap of believing that humans can succeed in the quest to control nature. Only by restructuring our global civilization based on the principles that have allowed Earth’s life and our ancestors to survive catastrophe——diversity, redundancy, a degree of self-sufficiency, social solidarity, and an aversion to excessive integration——can we restore the flexibility needed to weather the trials ahead. In this powerful and prescient book, Dumanoski moves beyond now-ubiquitous environmental buzzwords about green industries and clean energy to provide a new cultural map through this dangerous passage. Though the message is grave, it is not without hope. Lucid, eloquent, and urgent, The End of the Long Summer deserves a place alongside transformative works such as Silent Spring and The Fate of the Earth.

Enriching the Earth by Vaclav Smil Pdf

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.

Short Dialysis by Andrea Cambi Pdf

Vittorio E. Andreucci of keeping alive patients in terminal chronic Initially created with the purpose renal failure, dialysis has undergone improvements in methodology, and its final goal has become complete health rehabilitation and optimization of the quality of life of chronic dialysis patients. To achieve this, many investigators have attempted to increase dialysis efficiency and at the same time shorten dialysis time. Their main concern was, obviously, patient safety: the Latin proverb 'primum non nocere' is still valid all over the world. Thus, when clinical observations of the first patients on regular dialysis therapy suggested an inverse relationship between duration of dialysis sessions and severity of peripheral neuropathy, long and frequent dialysis sessions were considered the only way to prevent the catastrophic consequences of nerve damage and underdialysis syndrome. It was then, in 1971, when dialysis duration was 8- 12 hours per session, that Vincenzo Cambi started a 'short dialysis' trial, i. e. , 4 hours 3 times weekly or 3 hours every second day. For the first time, dialysis was shortened from 24-36 hours weekly to 10. 5-12 hours weekly [1, 2]. In 1971 I was still at the Parma University Hospital. We had both just returned from the United States, and Dr. Cambi was responsible for the dia lysis unit.

UNEP Year Book 2009 by United Nations Pdf

UNEP Year Book 2009: New Science and Developments in our Changing Environment presents work in progress on scientific understanding of global environmental change, as well as foresight about possible issues on the horizon. The aim is to raise awareness of the interlinkages among environmental issues that can accelerate the rates of change and threaten human wellbeing. The chapters of the Year Book track the same trajectory as our awareness of environmental change. Transformations are inherent to this trajectory and are taking place on many fronts: from industrial agriculture to eco-agriculture; from a wasteful society towards a resource efficient one; and from a triad of competing interests among civil society, the private sector, and governments to a more cooperative model based on mutual benefits.
