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.

In the early 1960s, Marie Christine von Reibnitz (who would later become HRH Princess Michael of Kent) lived with her father on his farm in Mozambique. Then just a teenager, Princess Michael was entranced by the African landscape, by the wildlife and by the people she met. It was one of the happiest times of her life, and she recounts that it was an orphaned cheetah cub (called Tess) who played a huge part in making it so.

Could extinct species, like mammoths and passenger pigeons, be brought back to life? The science says yes. In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks listeners through the astonishing and controversial process of de-extinction.

As one of the world’s leading field biologists, George Schaller has spent much of his life traversing wild and isolated places in his quest to understand and conserve threatened species - from mountain gorillas in the Virunga to pandas in the Wolong and snow leopards in the Himalaya. Throughout his celebrated career, Schaller has spent more time in Tibet than in any other part of the world, devoting more than thirty years to the wildlife, culture, and landscapes that captured his heart and continue to compel him.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.

Many people think wild tigers are on the road to recovery, but they are in greater danger than ever - from a menace few experts saw coming. There may be only three thousand wild tigers left in the entire world. More shocking is the fact that twice that many - some six thousand - have been bred on farms, not for traditional medicine but to supply a luxury-goods industry that secretly sells tiger-bone wine, tiger-skin decor, and exotic cuisine enjoyed by China's elite.

Reissued on the 10th anniversary of its publication, this classic work on our environmental crisis features a new introduction by the author, reviewing both the progress and ground lost in the fight to save the Earth. This impassioned plea for radical and life-renewing change is today still considered a groundbreaking work in environmental studies. McKibben's argument that the survival of the globe is dependent on a fundamental, philosophical shift in the way we relate to nature is more relevant than ever.

For millennia, lions, tigers, and their man-eating kin have kept our dark, scary forests dark and scary, and their predatory majesty has been the stuff of folklore. But by the year 2150 big predators may only exist on the other side of glass barriers and chain-link fences. Their gradual disappearance is changing the very nature of our existence. We no longer occupy an intermediate position on the food chain; instead we survey it invulnerably from above - so far above that we are in danger of forgetting that we even belong to an ecosystem.

Rusty Wilson’s the kind of guy that if he sees you in town, he’ll buy you lunch. But since Rusty’s rarely in town, instead of buying you lunch, he’d like to give you a huge bargain price on a few of his stories so you can sample the crazy and mysterious world of Bigfoot. These great stories were collected by Rusty from his flyfishing clients around the campfire - and they’re stories you’ll never forget - even if you’d like to!

Naturalist Joe Hutto’s latest adventures in wildlife observation take him to Wyoming’s Wind River Mountains. Hutto is living in a tent at 12,000 feet, where blizzards occur in July and where human wants become irrelevant—and human needs can become a matter of life and death—to study the Rocky Mountain bighorn sheep.

Emmy Award - winning filmmaker, writer, and naturalist Joe Hutto has done it again. Touching the Wild is the enchanting story about one man who has lived with a herd of mule deer in the Wind River mountains of Wyoming for almost seven years. Why, you may ask, would a person choose to do such a thing? His response: how could you not? For Joe Hutto, close proximity to wild things is irresistible. In Illumination in the Flatwoods he unveiled the secret lives of the wild turkey to great critical acclaim.

It's no secret that our planet is in crisis. Environmental threats such as climate change, pollution, habitat loss, and land degradation threaten the survival of thousands of plant and animal species. In 100 Heartbeats, Jeff Corwin provides an urgent portrait of the wildlife teetering on the brink. 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, Corwin takes you on a global tour to witness firsthand the critical state of our natural world.

In 1992, in a remote mountain range, a team of scientists discovered the remains of an unusual animal with beautiful, long horns. It turned out to be a living species new to Western science - a saola, the first large land mammal discovered in 50 years.

Yes, the world faces substantial environmental challenges - climate change, pollution, and extinction. But the surprisingly good news is that we have solutions to these problems. In the past 50 years, a remarkable number of environmental problems have been solved while substantial progress is ongoing on others. The Optimistic Environmentalist chronicles these remarkable success stories. Endangered species - from bald eagles to gray whales - pulled back from the precipice of extinction.

A young man is murdered for his prized pet fish. An Asian tycoon buys a single specimen for $150,000. Meanwhile, a pet detective chases smugglers through the streets of New York. Delving into an outlandish realm of obsession, paranoia, and criminality, The Dragon Behind the Glass tells the story of a fish like none other: a powerful predator dating to the age of the dinosaurs.

America's Great Plains once possessed one of the grandest wildlife spectacles of the world, equaled only by such places as the Serengeti, the Masai Mara, or the veld of South Africa. Pronghorn antelope, gray wolves, bison, coyotes, wild horses, and grizzly bears: less than 200 years ago these creatures existed in such abundance that John James Audubon was moved to write "it is impossible to describe or even conceive the vast multitudes of these animals".

Interweaving her own first-hand experiences in the field with the compelling research of premier scientists, Goodall illuminates the heroic efforts of dedicated environmentalists and the truly critical need to protect the habitats of these beloved species. At once a celebration of the animal kingdom and a passionate call to arms, Hope for Animals and Their World presents an uplifting, hopeful message for the future of animal-human coexistence.

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.

Can you face a wild animal with the ability to eat, maul, or trample you, with only a bow and arrow in your hand? When you stare death in the face at less than 30 yards, can you control your fear and the adrenaline rush that hits you, and do you have enough confidence in your shooting skills and your bow’s ability to perform the task before it? In this audiobook, you’ll meet some amazing bowhunters who’ve had dreams of hunting dangerous game and have realized those dreams.

Journalist Christopher Ketcham has been documenting the confluence of commercial exploitation and governmental misconduct in this region for over a decade. His revelatory book takes the listener on a journey across these last wild places, to see how capitalism is killing our great commons.

When it comes to the natural world, Australia is home to a disproportionately large share of the world's riches. That means we Australians are caretakers of a unique natural heritage in a land which tolerates few mistakes. So how are we doing? In Quarterly Essay 48 Tim Flannery says: we're often failing nature. In the clash between money and conservation, money usually wins.

The Galápagos archipelago is often viewed as a last foothold of pristine nature. For 60 years, conservationists have worked to restore this evolutionary Eden after centuries of exploitation at the hands of pirates, whalers, and island settlers. This book tells the story of the islands' namesakes - the giant tortoises - as coveted food sources, objects of natural history, and famous icons of conservation and tourism. By doing so, it brings into stark relief the paradoxical, and impossible, goal of conserving species by trying to restore a past state of prehistoric evolution.

Most of us have heard of such popular butterflies as the Monarch or Painted Lady. But what about the Fender's Blue? Or the St. Francis' Satyr? Because of their extreme rarity, these butterflies are not well-known, yet they are remarkable species with important lessons to teach us. The Last Butterflies spotlights the rarest of these creatures - some numbering no more than what can be held in one hand.

Eighteen years ago, Stanford MBA Michele Raffin pulled off the road to help an injured dove, a momentary impulse that ignited in her a fervent commitment to saving vulnerable bird species. Today, her suburban home plays host to Pandemonium Aviaries, one of the largest avian rescue sanctuaries and endangered breeding facilities in the country, with a maze of 54 individual aviaries that house over 40 species, 14 of which are listed as threatened with extinction.

The sixth "mass extinction event" in the history of planet Earth is currently under way, with over two hundred species dying off every day. The cause of this seismic event is also the source of the single biggest threat to human life: our own inventions. But for all our talk about sea levels and biotechnology, do we really know what our future will actually look like? Will our immune systems be attacked by so-called super bugs, always evolving, and more easily spread than ever? Will the disappearance of numerous species cripple the biosphere?

Rat Island rises from the icy gray waters of the Bering Sea, a mass of volcanic rock covered with tundra, midway between Alaska and Siberia. Once a remote sanctuary for enormous flocks of seabirds, the island gained a new name when shipwrecked rats colonized, savaging the nesting birds by the thousands. Now, on this and hundreds of other remote islands around the world, a massive - and massively controversial - wildlife rescue mission is underway.

The remarkable story of the heroic effort to save and preserve Afghanistan's wildlife - and a culture that derives immense pride and a sense of national identity from its natural landscape.

Several years ago, ecologist Lauren E. Oakes set out from California for Alaska's old-growth forests to hunt for a dying tree: the yellow-cedar. With climate change as the culprit, the death of this species meant loss for many Alaskans. Oakes and her research team wanted to chronicle how plants and people could cope with their rapidly changing world. Amidst the standing dead, she discovered the resiliency of forgotten forests, flourishing again in the wake of destruction, and a diverse community of people who persevered to create new relationships with the emerging environment.

In 2006, vaquita, a diminutive porpoise making its home in the Upper Gulf of California, inherited the dubious title of world's most endangered marine mammal. When international crime cartels discovered a lucrative trade in the swim bladders of totoaba, illegal gillnetting went rampant, and now the lives of the few remaining vaquitas hang in the balance. Author Brooke Bessesen takes us on a journey to Mexico's Upper Gulf region to uncover the story. She interviewed townspeople, fishermen, scientists, and activists, teasing apart a complex story filled with villains and heroes.

In Unnatural Companions, journalist Peter Christie issues a call to action for pet owners. If we hope to reverse the alarming trend of wildlife decline, pet owners must acknowledge the pets-versus-conservation dilemma and concede that our well-fed and sheltered cats too often prey on small backyard wildlife and seemingly harmless reptiles released into the wild might be the next destructive invasive species. We want our pets to eat nutritionally healthy food, but how does the designer food we feed them impact the environment?
