Most of us give little thought to the hidden systems that bring us water and take it away when we’re done. But these underappreciated marvels of engineering face an array of challenges that cannot be solved without a fundamental change to our relationship with water.

Thank you for choosing this book - it shows that you care about the future of our planet. Whether you decide to go plastic free for an hour, a day or a year, this book will equip you with little steps we can each take to make a big difference. Let's turn the tide on plastic now - our oceans will...

As a changing climate threatens the whole country with deeper droughts and more furious floods that put ever more people and property at risk, Texas has become a bellwether state for water debates. Will there be enough water for everyone? Is there the will to take the steps necessary to defend ourselves against the sea? Is it in the nature of Americans to adapt to nature in flux?

By 2030, experts predict two-thirds of people living on this planet will not have enough water, a situation expected to result in the deaths of millions and an unprecedented rise in military conflicts. Can we as individuals hope to reverse these dire predictions? Award-winning author and water activist Florencia Ramirez believes we can if our conservation efforts focus on the 70 percent of freshwater flowing to the fields and ranches that grow our food. Eat Less Water takes the listener on a journey to meet America's food producers growing food with less water.

The story of the American West is the story of a relentless quest for a precious resource: water. It is a tale of rivers diverted and dammed, of political corruptions and intrigue, of billion-dollar battles over water rights, of ecologic and economic disaster. In Cadillac Desert, Marc Reisner writes of the earliest settlers, lured by the promise of paradise, and of the ruthless tactics employed by Los Angeles politicians and business interests to ensure the city's growth. He documents the bitter rivalry between two government giants to transform the West.

Pollution is the single largest cause of death in the developing world. One in seven people in low- and middle-income countries die as a result of it. Simply put, pollution is now the world's most prevalent health risk. And yet, while most everyone has heard about "going green"; few are aware of the more dire and sinister brown pollution - places where man-made toxic pollutants have taken root and spread. Brown sites poison millions of people every year, causing needless suffering and death. After witnessing several brown sites firsthand and meeting families trapped by poverty in these toxic hot spots, environmentalist Richard Fuller founded the Blacksmith Institute, now renamed Pure Earth, a global nonprofit that initiates large-scale cleanups of some of the most polluted places on earth.

Perhaps the first environmental engineer at Hanford, Melvin R. Adams spent 24 years on its 586 square miles of desert terrain. His thoughtful vignettes recall challenges and sites he worked on or found personally intriguing - like the 216-U-pond, contaminated with plutonium longer than any other place in the world.

Più volte, negli ultimi decenni, l'Italia è diventata protagonista in negativo delle prime pagine dei giornali, nazionali e internazionali, a causa della cosiddetta "emergenza rifiuti". Le città d'arte del Belpaese sommerse dai rifiuti sono un'immagine che purtroppo ricorre periodicamente, suscitando l'interesse momentaneo della classe politica di turno per poi ritornare nell'oblio senza che sia stata trovata una soluzione definitiva.

“Wonderfully written…Mr. Owen writes about water, but in these polarized times the lessons he shares spill into other arenas. The world of water rights and wrongs along the Colorado River offers hope for other problems.” —Wall Street Journal An eye-opening account of where our water...

Die Energiewende steckt in einer tiefen Krise: Regierungspolitiker räumen mittlerweile ein, dass kaum etwas in dem deutschen Musterschülerprojekt nach Plan läuft. Millionen Stromkunden bringen mehr als 20 Milliarden Euro an jährlichen Subventionen auf, während nur wenige profitieren. Das...

Strategically situated at the gateway to the Mississippi River yet standing atop a former swamp, New Orleans was from the first what geographer Peirce Lewis called an "impossible but inevitable city". How New Orleans came to be, taking shape between the mutual and often contradictory forces of nature and urban development, is the subject of An Unnatural Metropolis.

The grid is an accident of history and of culture, in no way intrinsic to how we produce, deliver and consume electrical power. Yet this is the system the United States ended up with, a jerry-built structure now so rickety and near collapse that a strong wind or a hot day can bring it to a grinding halt. The grid is now under threat from a new source: renewable and variable energy, which puts stress on its logics as much as its components.

It’s a cruel 21st-century paradox that the poor of the earth have more trouble accessing a toilet than a cell phone. For lack of a loo, fast-growing populations in cities of the developing world are suffering daily indignities and waves of infectious disease. No Place To Go takes an unblinking look at scenes from a sanitation crisis in the Ghanaian city of Kumasi while profiling a spirited, buck-the-odds start-up team that is trying to do something about it.

Lengthy investigations revealed cover ups, covert operations, reckless corporate management, numerous safety violations, and a broken regulatory process. At the time of the spill, oil flowed through the Alyeska pipeline at a profit of $400,000 per hour, yet in the end, the 10,000 fishermen affected by the spill spent nearly 20 years in litigation and received little compensation for their losses. Despite a massive cleanup effort, oil remains on the beaches and continues to impact marine life.

Why are we drawn to the ocean each summer? Why does being near water set our minds and bodies at ease? In Blue Mind, Wallace J. Nichols revolutionizes how we think about these questions, revealing the remarkable truth about the benefits of being in, on, under, or simply near water.

“A visionary roadmap for people who believe they can change the world—and invaluable advice about bringing together the partners and technologies to help them do it.” —President Bill Clinton A radical, how-to guide for using exponential technologies, moonshot thinking, and crowd-powered...

Sterilizing water is a big job. Solar electric (PV) powered UV water sterilizers are an effective way to sterilize your water from local polluted sources, even brackish water, with safety, reliability, and no fuel-costs. Water found in nature is full of pathogens which can cause disease and illness. Ultra-violet (UV) sterilizers kill 99.99% of all dangerous pathogens and render your water potable and safe to drink.

La esterilización de agua es un trabajo arduo. Los esterilizadores de agua energizados con electricidad solar FV son un medio efectivo para esterilizar agua desde fuentes locales polutas, aún agua salobre, con seguridad, fiable y sin costos de combustible. El agua encontrada en la naturaleza está llena de elementos patógenos que pueden causar infecciones y enfermedades. Los esterilizadores ultravioletas (UV) matan el 99.99% de todos los patógenos dañinos y aportan un agua potable y segura para beber.

Pump water from your well, or shallow surface source directly with Solar PV panels. Size your solar water pumping system with this step-by-step guide to defining, and building your solar water pumping project. Solar water pumping systems include solar PV panels, a controller, and the pump itself. The examples included in this audiobook match the model pump, with the solar power supply required to produce a given average water production per day.

Yellowstone National Park looks like a pristine western landscape populated by its wild inhabitants: bison, grizzly bears, and wolves. But the bison do not always range freely, snowmobile noise intrudes upon the park's profound winter silence, and some tourist villages are located in prime grizzly-bear habitat. Despite these problems, the National Park Service has succeeded in reintroducing wolves, allowing wildfires to play their natural role in park forests, and prohibiting a gold mine that would be present in other more typical western landscapes.
