"In mid-July of 1879, John Muir sailed for the first time through the sheer-walled fjords of Alaska's Inside Passage. 'Never before this,' he wrote, 'had I been embosomed in scenery so hopelessly beyond description.' During the previous 15 years, Muir had vanished into the north woods of Canada, walked a thousand miles from Kentucky to the Gulf of Mexico, and nested himself in the granite heart of California's Sierra Nevada mountains. Wild nature burned with volcanic intensity in the core of John Muir's soul."

Travelling the circumference of the truly gigantic Pacific, Simon Winchester tells the story of the world's largest body of water and - in matters economic, political and military - the ocean of the future. The Pacific is a world of tsunamis and Magellan, of the Bounty mutiny and the Boeing Company. It is the stuff of the towering Captain Cook and his wide-ranging network of exploring voyages, Robert Louis Stevenson and Admiral Halsey.

Alaska's Arctic National Wildlife Refuge, home to only a handful of people, is a harsh and lonely place. So when James Campbell's cousin Heimo Korth asked him to spend a summer building a cabin in the rugged Interior, Campbell hesitated about inviting his 15-year-old daughter, Aidan, to join him. Would she be able to withstand clouds of mosquitoes, the threat of grizzlies, bathing in an ice-cold river, and hours of grueling labor peeling and hauling logs? But once there, Aidan embraced the wild.

A paradigm shift is roiling the environmental world. For decades people have unquestioningly accepted the idea that our goal is to preserve nature in its pristine, pre-human state. But many scientists have come to see this as an outdated dream that thwarts bold new plans to save the environment and prevents us from having a fuller relationship with nature. Humans have changed the landscapes they inhabit since prehistory, and climate change means even the remotest places now bear the fingerprints of humanity.

When Guy Stagg decided to walk from Canterbury to Jerusalem, he spent the next 10 months following medieval pilgrim paths across 5,500 km. He began the journey after suffering several years of mental illness, hoping the ritual would heal him. Travelling alone and without support, he had to rely each night on the charity of strangers.

In the years following the publication of Into Thin Air, much has changed on Mount Everest. Among all the books documenting the glorious adventures in mountains around the world, and the unique perils and challenges of Mount Everest, none details how the recent infusion of wealth into the mountains is reacting with the age-old lust for glory to draw crime to the highest places on the planet.

When Desert Solitaire was first published in 1968, it became the focus of a nationwide cult. Rude and sensitive. Thought-provoking and mystical. Angry and loving. Both Abbey and this book are all of these and more. Here, the legendary author of The Monkey Wrench Gang, Abbey's Road and many other critically acclaimed books vividly captures the essence of his life during three seasons as a park ranger in southeastern Utah.

Before men ruled the earth, there were wolves. Once abundant in North America, these majestic creatures were hunted to near extinction in the lower 48 states by the 1920s. But in recent decades, conservationists have brought wolves back to the Rockies, igniting a battle over the very soul of the West. With novelistic detail, Nate Blakeslee tells the gripping story of one of these wolves, O-Six, a charismatic alpha female named for the year of her birth.

There are more than 180 exotic species in the Great Lakes. Some, such as the Asian tapeworm, have had little or no impact so far. But a handful of others - sea lamprey, alewife, spiny water flea, rusty crayfish, and more - have conducted an all-out assault on the Great Lakes and are winning the battle. Here, William Rapai focuses on the impact of these invasives. Rapai begins with a brief biological and geological history of the Great Lakes. He examines new policies and the tradeoffs that must be weighed, and ends with an inspired call for action.

John Muir, who was born in Scotland and emigrated to America in 1849, was an advocate of U.S. forest conservation and was largely responsible for the establishment of Sequoia and Yosemite national parks in California. Muir has emerged as perhaps the greatest prophet of an era which finds itself suddenly aware of the urgent need to care for our planet.

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.

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.

It is accepted wisdom today that human beings have irrevocably damaged the natural world. We have altered our climate, acidified our oceans, and we are in the process of causing the sixth mass extinction. Yet what if this gloomy narrative obscures a more hopeful truth? In Inheritors of the Earth, renowned ecologist and environmentalist Chris D. Thomas overturns this loss-only view of the world's biodiversity, revealing how many animals and plants have benefited from the human-altered planet.

Omega-3 fatty acids have long been celebrated by doctors and dieticians as key to a healthy heart and a sharper brain. In the last few decades, that promise has been encapsulated in one of America's most popular dietary supplements. Omega-3s are today a multi-billion dollar business, and sales are still growing apace - even as recent medical studies caution that the promise of omega-3s may not be what it first appeared.

Siamo abituati a pensare che le foreste siano statiche, che stiano lì, immobili, da sempre. Ma non è così. Semplicemente vivono, e cambiano, a un ritmo più lento del nostro. C'è, tuttavia, un momento in cui abbiamo la possibilità di apprezzarne il cambiamento, e, ironia della sorte, è proprio quando vi si abbatte una calamità o, come si dice in ecologia, un "disturbo". Che sia un incendio, un'alluvione, un'eruzione, ciò che segue non è l'estinzione totale. Al contrario.

Det brukar sägas att människan vet mer om rymden än om haven. Inte för att förolämpa Stephen Hawking och hans vänner, men eftersom vi inte vet rymdens exakta storlek går påståendet inte att bevisa. Det baseras främst på att vi skickat 12 människor till månen sedan 1969, jämfört med bara 3 till havets djupaste punkt, Marianergraven. Enligt NOAA (National Oceanic and Atmospheric Administration in the US), täcker haven 71 procent av jordklotets yta och innehåller 97 procent av jordklotets vatten.

Lothar Streblow unternahm viele Reisen im In- und Ausland, auf denen er sich mit Studien über Tiere, Verhaltensforschung und Ökologie befasste. Von diesen Erkenntnissen inspiriert, entstanden zahlreiche Radiosendungen, Hörspiele und Essays, sowie Umwelt-, Reise- und Tiererzählungen. Dabei versuchte er stets dem sachkundlichen Anspruch gerecht zu werden. In "Geister in der Nacht - Nationalpark Bayerischer Wald" begibt er sich auf die Spuren der Tier- und Pflanzenwelt im Bayerischen Wald.

Der Buchfink stimmt seinen wohlklingenden Gesang an, in der Ferne ruft ein Waldkauz, eingebettet von hohen Bäumen ruht ein Waldweiher...

Hoch oben auf dem Berg, da grasen die Kühe friedlich auf der Sommerweide, die Kuhglocken läuten, munter zwitschern die Vögel...
