Rivers, on a long view, are alive. They are born; they change; they shift their channels; they forge new routes to the sea; they move both gradually and violently; they can teem (usually) with life; they may die a quasi-natural death; they are frequently maimed and even murdered. It is the annual flood pulse—the brief time when the river occupies the floodplain—that gives a river its vitality, but it is human engineering that kills it, suppressing the flood pulse with dams, irrigation, siltation, dikes, and levees.

Combining accounts of legendary mountain ascents with vivid descriptions of his own forays into wild, high landscapes, Robert Macfarlane reveals how the mystery of the world's highest places has come to grip the Western imagination - and perennially draws legions of adventurers up the most perilous slopes. His story begins three centuries ago, when mountains were feared as the forbidding abodes of dragons and other mysterious beasts.

The story of the world's largest, longest, and best-financed scientific expedition of all time, triumphantly successful, gruesomely tragic, and never before fully told. The immense 18th-century scientific journey, variously known as the Second Kamchatka Expedition or the Great Northern Expedition, from St. Petersburg across Siberia to the coast of North America, involved over 3,000 people and cost Peter the Great over one-sixth of his empire's annual revenue.

Man’s struggle against the sea is a theme that has created some of the world’s most exciting stories. Now, in the tradition of Moby Dick comes a New York Times best seller destined to become a modern classic. Written by journalist Sebastian Junger, The Perfect Storm combines an intimate portrait of a small fishing crew with fascinating scientific data about boats and weather systems.

In this exciting true adventure mixed with amazing scientific study, a young, exuberant explorer and geoscientist journeys deep into the Amazon - where rivers boil and legends come to life. When Andrés Ruzo was just a small boy in Peru, his grandfather told him the story of a mysterious legend: There is a river, deep in the Amazon, that boils as if a fire burns below it. Twelve years later, Ruzo - now a geoscientist - hears his aunt mention that she herself had visited this strange river....

In a riveting investigation of the science and ecology of wildfires, journalist M.R. O'Connor ventures into some of the oldest, most beautiful, and remote forests in North America to explore the powerful and ancient relationship between trees, fires, and humans. Along the way, she describes revelatory research in the fields of paleobotany and climate science to show how the world's forests have been shaped by fire for hundreds of millions of years.

Zane Grey fished up to 300 days of the year. But, with all that time on the water, there was nothing more exciting or more compelling than the really big fish - the giants of the sea. In Zane Grey's day, blue fin tuna were pursued with harpoons and sometimes are even today. There is the story of a swordfish that was hooked at 10:30 in the morning and played until 11:30 that night - only to...! Tales of Swordfish and Tuna will dazzle and thrill any fishing heart.

The grizzly is one of North America's few remaining large predators. Their range is diminished, but they're spreading across the West again. Descending into valleys where once they were king, bears find the landscape they'd known for eons utterly changed by the new most dominant animal: humans. In searing detail, award-winning writer, Montana rancher, and conservationist Bryce Andrews tells us about one such grizzly. Millie is a typical mother: strong, cunning, fiercely protective of her cubs. But raising those cubs becomes ever harder as the climate warms and people crowd the valleys.

Dr Rosa is no stranger to the Amazon. Growing up with the rainforest as her back garden, she learnt the lessons of the rainforest from her grandmother, a native healer in natural medicine. In this debut, you'll learn about Dr Rosa's journeys in the Amazon: her treacherous encounters with a boiling river, her conservation work with stingless bees, her experience of taking ayahuasca as a natural psychedelic—and all the amazing biodiversity of the rainforest.

In 1963 Colin Fletcher became the first man to walk the length of Grand canyon, below the Rim. It began with a dream, when he and a friend detoured from a cross-country trip to take a hurried look at the great natural wonder. Standing on the Rim, surrounded by the profound and almost mystical silence, Fletcher knew that something had happened to the way he looked at things. He also knew that the Canyon, with its depths and distances, cliffs, buttes, and hanging terraces, beckoned to him, calling him on a journey that would challenge both his body and his mind.

Hailed as "the great nature writer of this generation" (Wall Street Journal), Robert Macfarlane is the celebrated author of books about the intersections of the human and the natural realms. In Underland, he delivers his masterpiece: an epic exploration of the Earth's underworlds as they exist in myth, literature, memory, and the land itself.

The dust storms that terrorized the High Plains in the darkest years of the Depression were like nothing ever seen before or since. Following a dozen families and their communities through the rise and fall of the region, Timothy Egan tells of their desperate attempts to carry on through blinding black dust blizzards, crop failure, and the death of loved ones. Brilliantly capturing the terrifying drama of catastrophe, he does equal justice to the human characters who become his heroes.

Science Be Dammed is an alarming reminder of the high stakes in the management - and perils in the mismanagement - of water in the Western United States. It seems deceptively simple: Even when clear evidence was available that the Colorado River could not sustain ambitious dreaming and planning by decision-makers throughout the 20th century, river planners and political operatives irresponsibly made the least sustainable and most dangerous long-term decisions.

Starting in November 2013 in a forest in Rwanda, where a modest spring spouts a trickle of clear, cold water, Levison Wood set forth on foot, aiming to become the first person to walk the entire length of the Nile. He followed the river for nine months, over 4,000 miles, through six nations - Rwanda, Tanzania, Uganda, South Sudan, the Republic of Sudan, and Egypt - to the Mediterranean coast.

The Title says it all. Anyone from the age of 12 upwards will gain an understanding of the amazing life that exists beneath the oceanic waves. Taking away the often hard to understand scientific terminology, this book was the first to be written in a straightforward way making it easy for anyone to read, understand and enjoy. The book describes the major groups of animals present in the sea, the soft-bodied animals; the cnidarians (jellyfish anemones, corals etc.), the crustaceans, (shrimps, crabs, lobsters, etc.) the molluscs, (the shellfish and squid etc.), the echinoderms (starfish, ...

Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built - and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.

In the winter of 1952, New England was battered by the most brutal nor’easter in years. As the weather wreaked havoc on land, the freezing Atlantic became a wind-whipped zone of peril, setting the stage for one of the most heroic rescue stories ever lived. On February 18, while the storm raged, two oil tankers, the Pendleton and the Fort Mercer, were in the same horrifying predicament. Built with “dirty steel,” and not prepared to withstand such ferocious seas, both tankers split in two, leaving the dozens of men on board utterly at the Atlantic’s mercy.

Bees are like oxygen: ubiquitous, essential, and, for the most part, unseen. While we might overlook them, they lie at the heart of relationships that bind the human and natural worlds. In Buzz, the beloved Thor Hanson takes us on a journey that begins 125 million years ago, when a wasp first dared to feed pollen to its young. From honeybees and bumbles to lesser-known diggers, miners, leafcutters, and masons, bees have long been central to our harvests, our mythologies, and our very existence. They've given us sweetness and light, the beauty of flowers, and as much as a third of the foodstuffs we eat. And, alarmingly, they are at risk of disappearing.

When painter Winslow Homer first sailed into the Gulf of Mexico, he was struck by its "special kind of providence." Indeed, the Gulf presented itself as America's sea - bound by geography, culture, and tradition to the national experience - and yet, there has never been a comprehensive history of the Gulf until now. And so, in this rich and original work that explores the Gulf through our human connection with the sea, environmental historian Jack E. Davis finally places this exceptional region into the American mythos in a sweeping history that extends from the Pleistocene age to the 21st century.
