Hardback. Condizione: Fair. *Winner of the Penn Libraries Book Prize in Sustainability* *Named a Best Book of the Year by Scientific American* This timely and captivating look at the hidden impact of light pollution is "rich in revelation and insight.lyrical" (The Wall Street Journal) and urges us to cherish natural darkness for the sake of the environment, our own well-being, and all life on earth. How much light is too much light? Satellite pictures show our planet as a brightly glowing orb, and in our era of constant illumination, light pollution has become a major issue. The world's flora and fauna have evolved to operate in the natural cycle of day and night. But in the last 150 years, we have extended our day--and in doing so have forced out the inhabitants of the night and disrupted the circadian rhythms necessary to sustain all living things, including ourselves. In this "well-researched and surprisingly lyrical" (The New Statesman, UK) book, Swedish conservationist Johan Eklöf urges us to appreciate natural darkness, its creatures, and its unique benefits. He ponders the beauties of the night sky, traces the errant paths of light-drunk moths and the swift dives of keen-eyed owls, and shows us the bioluminescent creatures of the deepest oceans. As a devoted friend of the night, Eklöf reveals the startling domino effect of diminishing darkness: insects, dumbfounded by streetlamps, failing to reproduce; birds blinded and bewildered by artificial lights; and bats starving as they wait in vain for insects that only come out in the dark. For humans, light-induced sleep disturbances impact our hormones and weight, and can contribute to mental health problems like chronic stress and depression. The streetlamps, floodlights, and neon signs of cities are altering entire ecosystems, and scientists are only just beginning to understand their long-term effects. The light bulb--long the symbol of progress and development--needs to be turned off. "Urgent.vivid.eye-opening" (Publishers Weekly), and ultimately encouraging, The Darkness Manifesto outlines simple steps that we can take to benefit ourselves and the planet. In order to ensure a bright future, we must embrace the darkness.…

Paperback. Condizione: Good. Clean Water is a book for anyone concerned about this precious resource who wants to become better informed. In straightforward language, Kenneth Vigil provides a comprehensive introduction to the many scientific, regulatory, cultural, and geographic issues associated with water quality and water pollution control.Most other books on water quality and pollution control are highly technical and very specific, and are aimed at engineers, scientists, or attorneys. Clean Water, on the other hand, is a comprehensive discussion of the subject intended for a wider audience of science students, educators, and the general public.Vigil avoids the use of technical jargon and uses many photos and diagrams to illustrate and explain concepts. He provides sufficient detail to educate readers about many broad topics and includes additional references at the end of each chapter for exploring specific topics in more detail.Clean Water summarizes the basic fundamentals of water chemistry and microbiology and outlines important water quality rules and regulations, all in concise, understandable prose. It describes the basic scientific principles behind water pollution control and the broader approach of addressing water pollution problems through watershed management. There are sections on drinking water and on citizen involvement in water pollution control efforts at home and in the community.This is a thoroughly revised edition of Vigil's 1996 book, Clean Water: The Citizen's Complete Guide to Water Quality and Water Pollution Control, which was praised by reviewers and has been used as a textbook at colleges and high schools throughout the U.S.…

Paperback. Condizione: Very Good. In When Smoke Ran Like Water , the world-renowned epidemiologist Devra Davis confronts the public triumphs and private failures of her lifelong battle against environmental pollution. She documents the shocking toll of a public-health disaster-300,000 deaths a year in the U.S. and Europe from the effects of pollution-and asks why we remain silent.
