Into the Deep is your gateway into Earth's last unexplored frontier: the ocean. With 10 captivating chapters that unravel the deep sea's most astonishing, mysterious, and mind-bending phenomena, this book is crafted for curious minds of all ages. Whether you're a budding marine biologist, a lifelong ocean lover, or someone who marvels at the wonders of nature, this journey into the abyss will leave you awestruck.

Russian spies. Nuclear submarines. Sabotaged pipelines. Undersea communications severed in the dark of night. The fastest-warming place on earth—where apartment buildings, hospitals, and homes crumble daily as permafrost melts and villages get washed away by rising seas—the Arctic stands at the crossroads of geopolitical ambition and environmental catastrophe. As climate change thaws the northern latitudes, opening once ice-bound shipping lanes and access to natural resources, the world’s military powers are rushing to stake their claims in this increasingly strategic region.

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.

Fennec foxes’ ears can be up to half as long as their bodies. They use them to track movement across the Sahara Desert, including under the sand. In this episode, we follow a fox as he meanders home to his family through the sand dunes as they slowly shift with the wind.

Crows have long been the subject of folklore, likely because they’re strikingly similar to humans, leading lives rich in personality, intelligence, and relationships. In this episode, we fly the streets of Seattle with a crow as she grooms her mate, delivers what appears to be a gift, and finally commutes miles away from her territory to gather and chat with thousands of other crows before it’s time to roost for the night.

In Hurricane Lizards and Plastic Squid, biologist Thor Hanson tells the remarkable story of how plants and animals are responding to climate change: adjusting, evolving, and sometimes dying out. Anole lizards have grown larger toe pads, to grip more tightly in frequent hurricanes. Warm waters cause the development of Humboldt squid to alter so dramatically that fishermen mistake them for different species. Brown pelicans move north, and long-spined sea urchins south, to find cooler homes.

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....

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.

Forced to accept that intensive farming on the heavy clay of their land at Knepp was economically unsustainable, Isabella Tree and her husband, Charlie Burrell, made a spectacular leap of faith: they decided to step back and let nature take over. Thanks to the introduction of free-roaming cattle, ponies, pigs and deer - proxies of the large animals that once roamed Britain - the 3,500 acre project has seen extraordinary increases in wildlife numbers and diversity in little over a decade.

In Eager, environmental journalist Ben Goldfarb reveals that our modern idea of what a healthy landscape looks like and how it functions is wrong, distorted by the fur trade that once trapped out millions of beavers from North America's lakes and rivers. The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of "Beaver Believers" recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them.

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.

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.

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.

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.

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.

Elephants are the largest land animals in the world. They are also intensely social and have advanced long-term memories. In this episode, a parade of Asian elephants makes its way through the Sri Lankan forest to a lake for drinks and mud baths, stopping periodically for group naps. The female leading the parade uses infrasonic rumbles—inaudible to humans, but traveling as far as two miles along the surface of the Earth as seismic waves—to invite friends and family around the forest to join her at the reservoir.

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.

“I went to the woods because I wished to live deliberately.” And so it began. Henry David Thoreau, at 27, built a tiny, one-room cabin in the woods — on land owned by his friend, Ralph Waldo Emerson — and began his two-year experiment in frugality on the shore of Walden Pond. He wasn’t seeking isolation so much as simplicity, to “live deep and suck out all the marrow of life, to live so sturdily and Spartan-like as to put to rout all that was not life, to cut a broad swath and shave close, to drive life into a corner, and reduce it to its lowest terms.”

Humpback whales are among the most intelligent animals on Earth. Some scientists believe they might even surpass humans in self-awareness, empathy, and communication skills. In this episode, we swim with a whale as he teams up with other humpbacks to use bubbles to catch fish, rescues a sea lion, and puts his own spin on melodies sung by whales across the Pacific Ocean. This is the world in its natural state, defined by seasons, routines, and cycles. By the time this whale is ready to close one eye and go to sleep, you will be too.
