    At immediate issue was whether the Park Service should have done more to keep bears away from humans, but what was revealed as the trial unfolded was just how fruitless our efforts to regulate nature in the parks had always been. The proceedings drew to the witness stand some of the most important figures in twentieth century wilderness management, including the eminent zoologist A. Starker Leopold, who had produced a landmark conservationist document in the 1950s, and all-American twin researchers John and Frank Craighead, who ran groundbreaking bear studies at Yellowstone. Their testimony would help decide whether the government owed the Walker family restitution for Harry's death, but it would also illuminate decades of patchwork efforts to preserve an idea of nature that had never existed in the first place.  In this remarkable excavation of American environmental history, nature writer and former park ranger Jordan Fisher Smith uses Harry Walker's story to tell the larger narrative of the futile, sometimes fatal, attempts to remake wilderness in the name of preserving it. Tracing a course from the founding of the national parks through the tangled twentieth-century growth of the conservationist movement, Smith gives the lie to the portrayal of national parks as Edenic wonderlands unspoiled until the arrival of Europeans, and shows how virtually every attempt to manage nature in the parks has only created cascading effects that require even more management. Moving across time and between Yellowstone, Yosemite, and Glacier national parks, Engineering Eden shows how efforts at wilderness management have always been undone by one fundamental problem--that the idea of what is "wild" dissolves as soon as we begin to examine it, leaving us with little framework to say what wilderness should look like and which human interventions are acceptable in trying to preserve it.    In the tradition of John McPhee's The Control of Nature and Alan Burdick's Out of Eden, Jordan Fisher Smith has produced a powerful work of popular science and environmental history, grappling with critical issues that we have even now yet to resolve.

    Lopez’s classic, careful study has won praise from a wide range of reviewers and improved the way books on wild animals are written. Of Wolves and Men explores the uneasy interaction between wolves and civilization over the centuries, and the wolf's prominence in our thoughts about wild creatures. Drawing upon an impressive array of literature, history, science, and mythology as well as extensive personal experience with captive and free-ranging wolves, Lopez argues for the wolf's preservation and immerses the reader in its sensory world, creating a compelling portrait of the wolf both as a real animal and as imagined by different kinds of men. A scientist might perceive the wolf as defined by research data, while an Eskimo hunter sees a family provider much like himself. For many Native Americans the wolf is also a spiritual symbol, a respected animal that can strengthen the individual and the community. With irresistible charm and elegance, Of Wolves and Men celebrates careful scientific fieldwork, dispels folklore that has enabled the Western mind to demonize wolves, explains myths, and honors indigenous traditions, allowing us to understand how this remarkable animal has become so prominent for so long in the human heart.

    In his startling new book, J. R. McNeill gives us our first general account of what may prove to be the most significant dimension of the twentieth century: its environmental history. To a degree unprecedented in human history, we have refashioned the earth's air, water, and soil, and the biosphere of which we are a part. Based on exhaustive research, McNeill's story—a compelling blend of anecdotes, data, and shrewd analysis—never preaches: it is our definitive account. This is a volume in The Global Century Series (general editor, Paul Kennedy).ContentsList of maps and tablesForeword by Paul KennedyAcknowledgmentsPreface1.

    For example, I was once pinned down by a young lad who repeatedly asked me why I was hitting myself, when he knew full well that I had temporarily ceded hegemony over my hands and forearms. I tried to explain it to him, but he didn’t seem to comprehend. In retrospect, I can only conclude that my explanation was not articulate enough.To that end, I and Phil Plait have teamed up to create precisely 128 insults designed to weaken the resolve of aggressors, while educating them in their primary field of interest. Whether the person pummeling you is a student of mathematics or belles-lettres, we have the right words for the occasion.Zach WeinersmithPS: In the highly likely situation that the person pummeling you refuses to cease his aggression until he understands the meaning of the insult, we have also provided an appendix in which the insults are explained.

    Recycle. Fly less. Eat less meat. These are some of the ways that we've been told can slow climate change. But the inordinate emphasis on individual behavior is the result of a marketing campaign that has succeeded in placing the responsibility for fixing climate change squarely on the shoulders of individuals.Fossil fuel companies have followed the example of other industries deflecting blame (think "guns don't kill people, people kill people") or greenwashing (think of the beverage industry's "Crying Indian" commercials of the 1970s). Meanwhile, they've blocked efforts to regulate or price carbon emissions, run PR campaigns aimed at discrediting viable alternatives, and have abdicated their responsibility in fixing the problem they've created. The result has been disastrous for our planet.In The New Climate War, Mann argues that all is not lost. He draws the battle lines between the people and the polluters-fossil fuel companies, right-wing plutocrats, and petrostates. And he outlines a plan for forcing our governments and corporations to wake up and make real change, including:A common-sense, attainable approach to carbon pricing- and a revision of the well-intentioned but flawed currently proposed version of the Green New Deal;Allowing renewable energy to compete fairly against fossil fuelsDebunking the false narratives and arguments that have worked their way into the climate debate and driven a wedge between even those who support climate change solutionsCombatting climate doomism and despair-mongeringWith immensely powerful vested interests aligned in defense of the fossil fuel status quo, the societal tipping point won't happen without the active participation of citizens everywhere aiding in the collective push forward. This book will reach, inform, and enable citizens everywhere to join this battle for our planet.

    In Dark Winter, author John L. Casey, a former White House national space policy advisor, NASA headquarters consultant, and space shuttle engineer tells the truth about ominous changes taking place in the climate and the Sun.Casey’s research into the Sun’s activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next thirty years or more. This new cold climate will dramatically impact the world’s citizens. In Dark Winter, he provides evidence of the following:• The end of global warming• The beginning of a “solar hibernation,” a historic reduction in the energy output of the Sun• A long-term drop in Earth’s temperatures• The start of the next climate change to decades of dangerously cold weather• The high probability of record earthquakes and volcanic eruptionsA sobering look at Earth’s future, Dark Winter predicts worldwide, crop- destroying cold; food shortages and riots in the United States and abroad; significant global loss of life; and social, political, and economic upheaval.

    In The Moth Snowstorm Michael McCarthy, one of Britain's leading writers on the environment, proposes this joy as a defence of a natural world which is ever more threatened, and which, he argues, is inadequately served by the two defences put forward hitherto: sustainable development and the recognition of ecosystem services.Drawing on a wealth of memorable experiences from a lifetime of watching and thinking about wildlife and natural landscapes, The Moth Snowstorm not only presents a new way of looking at the world around us, but effortlessly blends with it a remarkable and moving memoir of childhood trauma from which love of the natural world emerged. It is a powerful, timely, and wholly original book which comes at a time when nature has never needed it more.

    A Passion for Nature is the most complete account of the great conservationist and founder of the Sierra Club ever written. It is the first to be based on Muir's full private correspondence and to meet modern scholarly standards. Yet it is also full of rich detail and personal anecdote, uncovering the complex inner life behind the legend of the solitary mountain man. It traces Muir from his boyhood in Scotland and frontier Wisconsin to his adult life in California right after the Civil War up to his death on the eve of World War I. It explores his marriage and family life, his relationship with his abusive father, his many friendships with the humble and famous (including Theodore Roosevelt and Ralph Waldo Emerson), and his role in founding the modern American conservation movement. Inspired by Muir's passion for the wilderness, Americans created a long and stunning list of national parks and wilderness areas, Yosemite most prominent among them. Yet the book also describes a Muir who was a successful fruit-grower, a talented scientist and world-traveler, a doting father and husband, a self-made man of wealth and political influence. A man for whom mountaineering was "a pathway to revelation and worship."For anyone wishing to more fully understand America's first great environmentalist, and the enormous influence he still exerts today, Donald Worster's biography offers a wealth of insight into the passionate nature of a man whose passion for nature remains unsurpassed.

    We've created, in very short order, a new planet, still recognizable but fundamentally different. We may as well call it Eaarth.That new planet is filled with new binds and traps. A changing world costs large sums to defend--think of the money that went to repair New Orleans, or the trillions it will take to transform our energy systems--but the endless economic growth that could underwrite such largesse depends on the stable planet we've managed to damage and degrade. We can't rely on old habits any longer.Our hope depends, McKibben argues, on scaling back—on building the kind of societies and economies that can hunker down, concentrate on essentials, and create the type of community (in the neighborhood but also on the internet) that will allow us to weather trouble on an unprecedented scale. Change—fundamental change—is our best hope on a planet suddenly and violently out of balance.
