Sloths are the slowest mammals on earth. They can hardly see. They live in rainforests among jaguars, pumas, and countless other predators. Yet they survive. And they do it by being so incredibly slow, and living a life covered in algae. In this episode, we hang with a sloth in the jungle of Costa Rica as he spends a month digesting one single leaf, and we see the symbiosis and collaboration that surrounds him.

Jacques Ellul’s The Technological Society has become a classic in its field, laying the groundwork for all other studies of technology and society that have followed. Ellul offers a penetrating analysis of our technological civilization, showing how technology - which began innocuously enough as a servant of humankind - threatens to overthrow humanity itself in its ongoing creation of an environment that meets its own ends. No conversation about the dangers of technology and its unavoidable effects on society can begin without a careful listening of this book.

In this delightful, acclaimed bestseller, one of the world’s leading cognitive scientists tackles the workings of the human mind. What makes us rational—and why are we so often irrational? How do we see in three dimensions? What makes us happy, afraid, angry, disgusted, or sexually aroused? Why do we fall in love? And how do we grapple with the imponderables of morality, religion, and consciousness?

Traditionally, Americans learned in school that the ancestors of the people who inhabited the Western Hemisphere at the time of Columbus' landing had crossed the Bering Strait 12,000 years ago; existed mainly in small nomadic bands; and lived so lightly on the land that the Americas were, for all practical purposes, still a vast wilderness. But as Charles C. Mann now makes clear, archaeologists and anthropologists have spent the last 30 years proving these and many other long-held assumptions wrong.

Dismantling New Age cults, wellness grifters, and conspiracy-mad yogis. At best, the conspirituality movement attacks public health efforts in times of crisis. At worst, it fronts and recruits for the fever-dream of QAnon. As the alt-right and New Age horseshoe toward each other in a blur of disinformation, clear discourse, and good intentions get smothered. Charismatic influencers exploit their followers by co-opting conspiracy theories on a spectrum of intensity ranging from vaccines to child trafficking. In the process, spiritual beliefs that have nurtured creativity and meaning are ...

There have been many Clayton Thomas-Mullers: The child who played with toy planes as an escape from domestic and sexual abuse, enduring the intergenerational trauma of Canada's residential school system; the angry youngster who defended himself with fists and sharp wit against racism and violence, at school and on the streets of Winnipeg and small-town British Columbia; the tough teenager who, at 17, managed a drug house run by members of his family, and slipped in and out of juvie, operating in a world of violence and pain.

We live at the bottom of an ocean of air - 5,200 million million tons, to be exact. It sounds like a lot, but Earth’s atmosphere is smeared onto its surface in an alarmingly thin layer - 99 percent contained within 18 miles. Yet, within this fragile margin lies a magnificent realm - at once gorgeous, terrifying, capricious, and elusive. With his keen eye for identifying and uniting seemingly unrelated events, Chris Dewdney reveals to us the invisible rivers in the sky that affect how our weather works and the structure of clouds and storms and seasons, the rollercoaster of climate.

Thoreau's classic account of the solitary life, describing his attempts to simplify his life and sort out his priorities by living alone in a cabin beside Walden Pond for nearly two years, is one of the most influential books ever written. The bible of the environmental movement, Walden vividly portrays Thoreau's reverence for nature, and his understanding of the idea that nature is made up of crucially interrelated parts.

Psychologist Kevin Dutton has made a speciality of psychopathy, and is on first-name terms with many notorious killers. But unlike those incarcerated psychopaths, and all those depicted in movies and crime fiction, most are not violent, he explains. In fact, says Prof Dutton, they have a lot of good things going for them. Psychopaths are fearless, confident, charismatic and focused—qualities tailor-made for success in today's society.

Arctic explorer and American visionary Walter Wellman pioneered both polar and trans-Atlantic airship aviation, making history’s first attempts at each. Wellman has been cast as a self-promoting egomaniac known mostly for his catastrophic failures. Instead he was a courageous innovator who pushed the boundaries of polar exploration and paved the way for the ultimate conquest of the North Pole—which would be achieved not by dogsled or airplane, but by airship.

They say that only truck drivers experience the true grandeur and landscape of America. In A Trucker's Tale, Ed Miller gives an inside look at the allure of the work and the colorful characters who haul our goods on the open road. He shares what it was like to grow up in a trucking family, his experience as an equipment officer in Vietnam, and the trials and tribulations of life as a trucker. His tales are often funny, sometimes sad, cringeworthy, or unbelievable. Many are the results of what he calls "just plain stupidity."

Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the 20-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics.

Call it "Zen and the Art of Farming" or a "Little Green Book", Masanobu Fukuoka's manifesto about farming, eating, and the limits of human knowledge presents a radical challenge to the global systems we rely on for our food. At the same time, it is a spiritual memoir of a man whose innovative system of cultivating the earth reflects a deep faith in the wholeness and balance of the natural world. As Wendell Berry writes in his preface, the book "is valuable to us because it is at once practical and philosophical."

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.

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.

This is the third and last of Sir David’s great natural history books based on his TV series and completes his survey of the animal world that began with Life on Earth and continues with Living Planet. In Life on Earth, Sir David showed how each group of animals evolved. In Living Planet he looked at the way they have adapted to the whole range of habitats in which they live. Now, in Trials of Life, he completes the story by revealing how animals behave – and why.
