Each year they are seen by millions of visitors, and they have become as integral a part of the Tower as its ancient stones. But their role is even more important than that—legend has it that if the ravens should ever leave, the Tower will crumble into dust and great harm will befall the kingdom.The responsibility for ensuring that such a disaster never comes to pass falls to one man: the Ravenmaster. The current holder of the position is Yeoman Warder Christopher Skaife, and in this fascinating, entertaining and touching book he memorably describes the ravens’ formidable intelligence, their idiosyncrasies and their occasionally wicked sense of humour. The Ravenmaster is a compelling, inspiring and irreverent story that will delight and surprise anyone with an interest in British history or animal behaviour.

    The sea contains millions of species of animals and plants, but we have identified only a few thousand of them. The sea controls our planet's climate, but we do not really understand how. The sea is still the frontier, and yet it seems so familiar that we sometimes forget how little we know about it. Just as we are poised on the verge of exploiting the sea on an unprecedented scale—mining it, fertilizing it, fishing it out—this book reminds us of how much we have yet to learn. More than that, it chronicles the knowledge explosion that has transformed our view of the sea in just the past few decades, and made it a far more interesting and accessible place. From the Big Bang to that far-off future time, two billion years from now, when our planet will be a waterless rock; from the lush crowds of life at seafloor hot springs to the invisible, jewel-like plants that float at the sea surface; from the restless shifting of the tectonic plates to the majestic sweep of the ocean currents, Kunzig's clear and lyrical prose transports us to the ends of the Earth.Originally published in hardcover as The Restless Sea.

    Poaching was rampant, but it was loss of habitat that most endangered the gorillas. Weber and Vedder realized that the gorillas were doomed unless something was done to save their forest home. Over Fossey's objections, they helped found the Mountain Gorilla Project, which would inform Rwandans about the gorillas and the importance of conservation, while at the same time establishing an ecotourism project -- one of the first anywhere in a rainforest -- to bring desperately needed revenue to Rwanda. In the Kingdom of Gorillas introduces readers to entire families of gorillas, from powerful silverback patriarchs to helpless newborn infants. Weber and Vedder take us with them as they slog through the rain-soaked mountain forests, observing the gorillas at rest and at play. Today the population of mountain gorillas is the highest it has been since the 1960s, and there is new hope for the species' fragile future even as the people of Rwanda strive to overcome ethnic and political differences.

    Environmental threats such as climate change, pollution, habitat loss, and land degradation threaten the survival of thousands of plant and animal species each day. In 100 Heartbeats, conservationist and television host Jeff Corwin provides an urgent, palpable portrait of the wildlife that is suffering in silence and teetering on the brink of extinction. From the forests slipping away beneath the stealthy paws of the Florida panther, to the giant panda’s plight to climb ever higher in the mountains of China in search of sustenance, to the brutal poaching tactics that have devastated Africa’s rhinoceros and elephant populations, Corwin takes readers on a global tour to witness firsthand the critical state of our natural world. Along the way, he shares inspiring stories of battles being waged and won in defense of the earth’s most threatened creatures by the conservationists on the front lines. These stories of hope and progress underscore an important message: Our own survival, as well as that of the world’s wildlife, is in our hands. The race to save the planet’s most endangered wildlife is under way. Every heartbeat matters.

    In this evocative and lavishly illustrated narrative, Ken Burns and Dayton Duncan delve into the history of the park idea, from the first sighting by white men in 1851 of the valley that would become Yosemite and the creation of the world’s first national park at Yellowstone in 1872, through the most recent additions to a system that now encompasses nearly four hundred sites and 84 million acres.The authors recount the adventures, mythmaking, and intense political battles behind the evolution of the park system, and the enduring ideals that fostered its growth. They capture the importance and splendors of the individual parks: from Haleakala in Hawaii to Acadia in Maine, from Denali in Alaska to the Everglades in Florida, from Glacier in Montana to Big Bend in Texas. And they introduce us to a diverse cast of compelling characters—both unsung heroes and famous figures such as John Muir, Theodore Roosevelt, and Ansel Adams—who have been transformed by these special places and committed themselves to saving them from destruction so that the rest of us could be transformed as well.The National Parks is a glorious celebration of an essential expression of American democracy.

    Wars have been fought over it, revolutions have been triggered by it, national diets have been based on it, economies and livelihoods have depended on it. To the millions it has sustained, it has been a treasure more precious that gold. This book spans 1,000 years and four continents. From the Vikings to Clarence Birdseye, Mark Kurlansky introduces the explorers, merchants, writers, chefs and fisherman, whose lives have been interwoven with this prolific fish. He chronicles the cod wars of the 16th and 20th centuries. He blends in recipes and lore from the Middle Ages to the present. In a story that brings world history and human passions into captivating focus, he shows how the most profitable fish in history is today faced with extinction.

    And that’s just the beginning. Bill McKibben meets Bill Bryson in this seriously engaging look at one man’s decision to put his money where his mouth is and go off the grid for one year—while still living in New York City—to see if it’s possible to make no net impact on the environment. In other words, no trash, no toxins in the water, no elevators, no subway, no products in packaging, no air-conditioning, no television . . .What would it be like to try to live a no-impact lifestyle? Is it possible? Could it catch on? Is living this way more satisfying or less satisfying? Harder or easier? Is it worthwhile or senseless? Are we all doomed or can our culture reduce the barriers to sustainable living so it becomes as easy as falling off a log? These are the questions at the heart of this whole mad endeavor, via which Colin Beavan hopes to explain to the rest of us how we can realistically live a more “eco-effective” and by turns more content life in an age of inconvenient truths.

    Unlike their human counterparts, who must alter their environment to accommodate our physical limitations, animals are adaptable to an amazing range of conditions--i.e., radical changes in a creature's physiology take place to match the demands of the environment. Winter provides an especially remarkable situation, because of how drastically it affects the most elemental component of all life: water.Examining everything from food sources in the extremely barren winter landscape to the chemical composition that allows certain creatures to survive, Heinrich's Winter World awakens the largely undiscovered mysteries by which nature sustains herself through the harsh, cruel exigencies of winters

    The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society.This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.

    Each of us, too, is a landscape inscribed by memory and loss. One life-defining lesson Lauret Savoy learned as a young girl was this: the American land did not hate. As an educator and Earth historian, she has tracked the continent’s past from the relics of deep time; but the paths of ancestors toward her—paths of free and enslaved Africans, colonists from Europe, and peoples indigenous to this land—lie largely eroded and lost.In this provocative and powerful mosaic of personal journeys and historical inquiry across a continent and time, Savoy explores how the country’s still unfolding history, and ideas of “race,” have marked her and the land. From twisted terrain within the San Andreas Fault zone to a South Carolina plantation, from national parks to burial grounds, from “Indian Territory” and the U.S.-Mexico Border to the U.S. capital, Trace grapples with a searing national history to reveal the often unvoiced presence of the past.In distinctive and illuminating prose that is attentive to the rhythms of language and landscapes, she weaves together human stories of migration, silence, and displacement, as epic as the continent they survey, with uplifted mountains, braided streams, and eroded canyons.

    The ice sheet that covers it is 700 miles wide and 1,500 miles long, and is composed of nearly three quadrillion tons of ice. For the last 150 years, explorers and scientists have sought to understand Greenland--at first hoping that it would serve as a gateway to the North Pole, and later coming to realize that it contained essential information about our climate. Locked within this vast and frozen white desert are some of the most profound secrets about our planet and its future. Greenland's ice doesn't just tell us where we've been. More urgently, it tells us where we're headed.In The Ice at the End of the World, Jon Gertner explains how Greenland has evolved from one of earth's last frontiers to its largest scientific laboratory. The history of Greenland's ice begins with the explorers who arrived here at the turn of the twentieth century--first on foot, then on skis, then on crude, motorized sleds--and embarked on grueling expeditions that took as long as a year and often ended in frostbitten tragedy. Their original goal was simple: to conquer Greenland's seemingly infinite interior. Yet their efforts eventually gave way to scientists who built lonely encampments out on the ice and began drilling--one mile, two miles down. Their aim was to pull up ice cores that could reveal the deepest mysteries of earth's past, going back hundreds of thousands of years.Today, scientists from all over the world are deploying every technological tool available to uncover the secrets of this frozen island before it's too late. As Greenland's ice melts and runs off into the sea, it not only threatens to affect hundreds of millions of people who live in coastal areas. It will also have drastic effects on ocean currents, weather systems, economies, and migration patterns.Gertner chronicles the unfathomable hardships, amazing discoveries, and scientific achievements of the Arctic's explorers and researchers with a transporting, deeply intelligent style--and a keen sense of what this work means for the rest of us. The melting ice sheet in Greenland is, in a way, an analog for time. It contains the past. It reflects the present. It can also tell us how much time we might have left.

    The pages take the reader on a wild narrative ride through the world of squid science and adventure, along the way addressing some riddles about what intelligence is, and what monsters lie in the deep. In addition to squid, both giant and otherwise, Kraken examines other equally enthralling cephalopods, including the octopus and the cuttlefish, and explores their otherworldly abilities, such as camouflage and bioluminescence. Accessible and entertaining, Kraken is also the first substantial volume on the subject in more than a decade and a must for fans of popular science.

    Birds by the Shore is a book about discovering the natural life at the ocean's edge: the habits of shorebirds and seabirds, the movement of sand and water, the wealth of creatures that survive amid storm and surf. Against this landscape's rhythms, Ackerman revisits her own history--her mother's death, her father's illness and her hopes to have children of her own.This portrait of life at the ocean's edge will be relished by anyone who has walked a beach at sunset, or watched a hawk hover over a winter marsh, and felt part of the natural world. With a quiet passion and friendly, generous intelligence, it explores the way that landscape shapes our thoughts and perceptions and shows that home ground is often where we feel the deepest response to the planet.

    Forest rangers had assembled nearly ten thousand men  —  college boys, day workers, immigrants from mining camps  —  to fight the fire. But no living person had seen anything like those flames, and neither the rangers nor anyone else knew how to subdue them.Egan narrates the struggles of the overmatched rangers against the implacable fire with unstoppable dramatic force. Equally dramatic is the larger story he tells of outsized president Teddy Roosevelt and his chief forester, Gifford Pinchot. Pioneering the notion of conservation, Roosevelt and Pinchot did nothing less than create the idea of public land as our national treasure, owned by and preserved for every citizen. The robber barons fought Roosevelt and Pinchot’s rangers, but the Big Burn saved the forests even as it destroyed them: the heroism shown by the rangers turned public opinion permanently in their favor and became the creation myth that drove the Forest Service, with consequences still felt in the way our national lands are protected  —  or not —  today.

    For among the finches of Daphne Major, natural selection is neither rare nor slow: it is taking place by the hour, and we can watch.In this dramatic story of groundbreaking scientific research, Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself. The Beak of the Finch is an elegantly written and compelling masterpiece of theory and explication in the tradition of Stephen Jay Gould.With a new preface.
