Every city has an environmental story, perhaps none so dramatic as Pittsburgh's. Founded in a river valley blessed with enormous resources-three strong waterways, abundant forests, rich seams of coal-the city experienced a century of exploitation and industrialization that degraded and obscured the natural environment to a horrific degree. Pittsburgh came to be known as "the Smoky City," or, as James Parton famously declared in 1866, "hell with the lid taken off."Then came the storied Renaissance in the years following World War II, when the city's public and private elites, abetted by technological advances, came together to improve the air and renew the built environment. Equally dramatic was the sweeping deindustrialization of Pittsburgh in the 1980s, when the collapse of the steel industry brought down the smokestacks, leaving vast tracks of brownfields and riverfront. Today Pittsburgh faces unprecedented opportunities to reverse the environmental degradation of its history. In Devastation and Renewal, scholars of the urban environment post questions that both complicate and enrich this story. Working from deep archival research, they ask not only what happened to Pittsburgh's environment, but why. What forces-economic, political, and cultural-were at work? In exploring the disturbing history of pollution in Pittsburgh, they consider not only the sooty skies, but also the poisoned rivers and creeks, the mined hills, and scarred land. Who profited and who paid for such "progress"? How did the environment Pittsburghers live in come to be, and how it can be managed for the future?In a provocative concluding essay, Samuel P. Hays explores Pittsburgh's "environmental culture," the attitudes and institutions that interpret a city's story and work to create change. Comparing Pittsburgh to other cities and regions, he exposes exaggerations of Pittsburgh's environmental achievement and challenges the community to make real progress for the future. A landmark contribution to the emerging field of urban environmental history, Devastation and Renewal will be important to all students of cities, of cultures, and of the natural world.

An annihilation force of invading aliens. Human civilization on the brink of extinction. Earth’s only hope—seven cadets and the legendary starship they were never meant to command. No matter the cost, they will stop at nothing to survive. No matter the odds, they will fight to save their future. The distant future. Earth’s Alliance forces have emerged victorious from a brutal nine-year war with the mysterious Kastazi—a vicious, highly advanced alien race. In the dawn of a new peace, the Alliance Devastation Class starship California embarks on a mission of science and learning with a skeleton crew of seasoned officers, civilian students, and inexperienced military cadets in tow. For JD Marshall and Viv Nixon, gifted cadets and best friends, the mission holds special meaning: It offers an opportunity to prove themselves and begin to escape the long shadows of their legendary war hero parents. Suddenly ambushed by a second wave of invading Kastazi forces, JD and Viv make the impossible decision to spearhead a mutiny to save the California and everyone on it. In command and quickly out of options, they are forced to activate the ship's prototype Blink Reactor—an experimental technology they expect to send them to the safe, distant reaches of space. When their escape transports them to a reality they don’t recognize and reveals unimaginably terrifying secrets, they must fight their way home to save not just everyone they love but also humanity itself. Standing in their way are an insurmountable enemy, saboteurs from within, a mystery eons in the making, and the fabric of time and space itself.

A deeply compelling and poignant story about the tragic lessons of war and the endurance of memory. In the last months of World War II, a man wakes in a field in a country he does not know. Injured and with only flashes of memory coming back to him, he pulls himself to his feet and starts to walk, setting out on an extraordinary journey in search of his home, his past, and himself. His name is Owen. A war he has only a vague recollection of joining is in its dying days, and as he tries to get back to England, he becomes caught up in the flood of rootless people pouring through Europe. Among them is a teenage boy, and together they form an unlikely alliance as they cross battle-worn Germany. When they meet a troubled young woman, tempers flare and scars are revealed as Owen gathers up the shattered pieces of his life. No one is as he remembers, not even himself. How can he truly return home when he hardly recalls what home is?

Imagine a life of virtual reality -- a childhood contained in a controlled environment, with no human contact or experiences outside of the world of computer-generated images. Corgan has been genetically engineered by the Federation for quick reflexes, high intelligence, and physical superiority. Everything Corgan is, everything he has ever seen or done, was to prepare him for one moment: a bloodless, computer-controlled virtual war. When Corgan meets his two fellow warriors, he begins to question the Federation. Now Corgan must decide where his loyalties lie, what he's willing to fight for, and exactly what he wants in return. His decisions will affect not only these three virtual warriors, but all the people left on earth.
