生態系の頂点に立ち，近づきがたい野生動物ヒグマ．ヒトはいつどのような進化をたどってユーラシア大陸でヒグマと出会い，なぜ文化的に共存することになったのか?

With their towering, cinnamon-colored trunks and dusky green canopies, ponderosa pine has long been a charismatic icon of the American West. Yet a quiet unraveling has begun: in the past decade, in a vast area from Santa Fe to the Sierras, more than two hundred million ponderosa have died. While some trees will survive in cooler places, scientists estimate that by mid-century less than five percent of the ponderosa in the American Southwest may remain. As the very character of this vast region shifts, what will be left behind? And how can we come to terms with such profound loss?

Brown bears lead deeply cyclical lives. They need to gain sometimes hundreds of pounds during the warmer months to prepare for winter hibernation, a lifestyle that brings them into frequent contact with many other species’ cycles. In this episode, we meander through the Alaska peninsula with a bear and her cubs as she teaches them to hunt salmon at the falls, dig for clams along the coastal mudflats, and use the regional rubbing tree.

Some of the only truly feral cattle in the world wander a long-abandoned island off the northernmost tip of Scotland. A variety of wildlife not seen in many lifetimes has rebounded on the irradiated grounds of Chernobyl. A lush forest supports thousands of species that are extinct or endangered everywhere else on earth in the Korean peninsula's narrow DMZ.

The sun sinks over the Rio Grande, the mountains around it glow orange, and the world slows down. The Mexican free-tailed bats inside the Jornada Cave are just starting to stretch and murmur. In this episode, we visit the nursery where all the baby bats stay together, and we accompany a new mother as she journeys into the sky with the rest of her crew for a night of hunting bugs via echolocation.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

On 11 March 2011, a massive earthquake sent a 120-foot-high tsunami smashing into the coast of Northeast Japan. By the time the sea retreated, more than 18,000 people had been crushed, burned to death, or drowned. It was Japan's greatest single loss of life since the atomic bombing of Nagasaki. It set off a national crisis and the meltdown of a nuclear power plant. And even after the immediate emergency had abated, the trauma of the disaster continued to express itself in bizarre and mysterious ways.

To celebrate the 40th anniversary of the book’s first publication, David Attenborough has revisited Life on Earth, completely updating and adding to the original text, taking account of modern scientific discoveries from around the globe....

For listeners who enjoyed Finding the Mother Tree and The Hidden Life of Trees comes the first-ever book about a movement to restore biodiversity in our cities and towns by transforming empty lots, backyards, and degraded land into mini-forests. Author Hannah Lewis is the forest maker turning asphalt into ecosystems to save the planet, and she wants everyone to know they can do it too.

Published in 1951, The Sea Around Us is one of the most remarkably successful books ever written about the natural world. This classic work remains as fresh today as when it first appeared. Carson's writing teems with stunning, memorable images - the newly formed Earth cooling beneath an endlessly overcast sky, the centuries of nonstop rain that created the oceans, giant squids battling sperm whales hundreds of fathoms below the surface, and incredibly powerful tides moving 100 billion tons of water daily in the Bay of Fundy.

In May 2016, Fort McMurray, Alberta, the hub of Canada's oil industry, was overrun by wildfire. The multi-billion-dollar disaster turned entire neighbourhoods into firebombs and drove 90,000 people from their homes in a single afternoon. Through the story of this apocalyptic conflagration, John Vaillant explores the past and the future of our ever-hotter, more flammable world.

In his beloved book The Hidden Life of Trees, Peter Wohlleben revealed astonishing discoveries about the social networks of trees and how they communicate. Now, in The Power of Trees, he turns to their future, with a searing critique of forestry management, tree planting, and the exploitation of old growth forests. At the heart of The Power of Trees lies Wohlleben’s passionate plea: that our survival is dependent on trusting ancient forests, and allowing them to thrive.

A new generation of listeners is discovering why Rachel Carson's books have become cornerstones of the environmental and conservation movements.

Wit’s End isn’t just a state of mind. It’s the name of a gravel road, the address of a rundown, off-the-grid cabin, 120 shabby square feet of fixer-upper Patrick Hutchison purchased on a whim in the mossy woods of the Cascade Mountains in Washington state. To say Hutchison didn’t know what he was getting into is no more an exaggeration than to say he’s a man with nearly zero carpentry skills. Well, used to be. You can learn a lot over six years of renovations. CABIN is the story of those renovations, but it's also a love story; of a place, of possibilities, and of the process of construction.

The world is changing at a relentless pace. How can we slow down and act from a place of respect for all living things? The Sacred Balance shows us how.

Beavers, those icons of industriousness, have been gnawing down trees, building dams, shaping the land, and creating critical habitat in North America for at least a million years. Once one of the continent's most ubiquitous mammals, they ranged from the Atlantic to the Pacific, and from the Rio Grande to the edge of the northern tundra. Wherever there was wood and water, there were beavers - 60 million (or more) - and wherever there were beavers, there were intricate natural communities that depended on their activities.

Under the Sea Wind is a classic wilderness adventure to which all nature writing is compared. The hero of Under the Sea Wind is soon seen to be life itself, that quicksilver prize granted, for a brief time only, to the clever and the fortunate.

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.
