Dung beetles might sound dirty, but the ancient Egyptians believed their god took the form of a dung beetle to roll the morning sun across the sky every day. In this episode, we roll with dung beetles around the world as they push their precious dung—often in balls many times larger than they are—over Florida pastures, Armenian highlands, and the vast South African savanna.

After water and air, sand is the natural resource that we consume more than any other - even more than oil. Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. And, incredibly, we're running out of it. The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it - and sometimes, even kill for it.

In 2016, Amy Tan grew overwhelmed by the state of the world: Hatred and misinformation became a daily presence on social media, and the country felt more divisive than ever. In search of peace, Tan turned toward the natural world just beyond her window and, specifically, the birds visiting her yard. But what began as an attempt to find solace turned into something far greater—an opportunity to savor quiet moments during a volatile time, connect to nature in a meaningful way, and imagine the intricate lives of the birds she admired.

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".

A small reptile scurries across a rock under the hot sun. It's a lizard! Learn more about these desert animals.

What makes the modern world work? The answer to this deceptively simple question lies in four "grand transitions" of civilization - in populations, agriculture, energy, and economics - that have transformed the way we live.

Interest in psychedelic mushrooms has never been greater–or the science less definitive. Popular science writer and amateur mycologist Eugenia Bone reports on the state of psychedelics today, from microdosing to heroic trips, illustrating how “citizen science” and anecdotal accounts of the mushrooms’ benefits are leading the new wave of scientific inquiry into psilocybin. With her signature blend of first-person narrative and scientific rigor, Bone breaks down just how the complicated cocktail of psychoactive compounds is thought to interact with our brain chemistry.

The world today is undergoing the most rapid environmental transformation in human history—from climate change to deforestation. Scientists, ethnobotanists, indigenous peoples, and collectives of all kinds are closely studying trees and their biology to understand how and why trees function individually and collectively in the ways they do. In Twelve Trees, Daniel Lewis, curator and historian at one of the world’s most renowned research libraries, travels the world to learn about these trees in their habitats.

James Herriot brings back familiar and much-loved friends, including his partner Siegfried and his most lucrative patient, the delightful Tricki Woo. There are some some new arrivals too, such as the abandoned and terrified mongrol Titch who finds the perfect home with a gruff grocer and feral kittens Olly and Ginny who live in James and wife Helen's back garden. Above all, the veterinary practise in Darrowby is enlivened by a marvelouslly eccentric assistant, Calum Buchanan, who arrives with a pet badger and proceeds to add dogs, owls and a monkey called Mortimer to his growing menagerie.

In the midst of spiraling ecological devastation, multispecies feminist theorist Donna J. Haraway offers provocative new ways to reconfigure our relations to the earth and all its inhabitants. She eschews referring to our current epoch as the Anthropocene, preferring to conceptualize it as what she calls the Chthulucene, as it more aptly and fully describes our epoch as one in which the human and nonhuman are inextricably linked in tentacular practices.

Find out how animals survive Earth's most extreme regions! From the rain-drenched treetops to the sun-starved forest floor, the rain forest is a tough place to live. But many animals from geckos to jaguars thrive in this environment. Discover the amazing body parts and behaviors that make living there possible.

Some 40 million miles of roadways encircle the earth, yet we tend to regard them only as infrastructure for human convenience. While roads are so ubiquitous they're practically invisible to us, wild animals experience them as entirely alien forces of death and disruption. In Crossings, environmental journalist Ben Goldfarb travels throughout the United States and around the world to investigate how roads have transformed our planet. A million animals are killed by cars each day in the US alone, but as the new science of road ecology shows, the harms of highways extend far beyond roadkill.

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.

In what he says is the most important piece of environmental writing in his long and award-winning career, Mark Kurlansky, best-selling author of Salt and Cod, The Big Oyster, 1968, and Milk, among many others, employs his signature multi-century storytelling and compelling attention to detail to chronicle the harrowing yet awe-inspiring life cycle of salmon.

Among the more than 34,000 species of fish, few have the walleye's following—among anglers and diners, states conferring official status on the fish, and towns battling for recognition as the Walleye Capital of the World. And among those passionate fans, few know the walleye as well as Paul J. Radomski does—a fisheries biologist, lake ecology scientist, and old fisherman. In Walleye: A Beautiful Fish of the Dark he unspools the mysteries of this fascinating fish.

In 1994, a team led by fossil-hunting legend Tim White—"the Steve Jobs of paleoanthropology"—uncovered the bones of a human ancestor in Ethiopia's Afar region. The findings challenged many assumptions about human evolution and repudiated a half-century of paleoanthropological orthodoxy. An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must-listen for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.

Tristan Gooley helps listeners reconnect with nature by finding direction and searching for hidden clues in stars, clouds, water and more. Now, he turns his attention to perhaps nature’s most beloved feature – the stately, majestic tree. Every single tree tells us an epic story – if we know how to read it! Here you’ll discover hundreds of astonishing secrets hiding in plain sight among the living network of branches, trunks, roots, bark, leaves, buds, flowers, stumps and more.

Born in Boston, Stephen Bodio wandered into Magdalena, New Mexico, in the 1970s while on his way to Montana and never left. He was accompanied by Betsy Huntington, who was twenty years his senior; the couple had been inseparable from the day they met. After stumbling upon a vintage home along the highway, they settled into a country life; it was the perfect way for the two of them to make their lives together in an out-of-the-way place.

In this classic work that continues to inspire its many fans, James Lovelock deftly explains his idea that life on Earth functions as a single organism. Written for the non-scientist, Gaia is a journey through time and space in search of evidence with which to support a new and radically different model of our planet. In contrast to conventional belief that living matter is passive in the face of threats to its existence, the book explores the hypothesis that the Earth's living matter - air, ocean, and land surfaces - forms a complex system that has the capacity to keep the Earth a fit place for life.

When ecologist Carl Safina and his wife, Patricia, took in a near-death baby owl, they expected that, like other wild orphans they'd rescued, she'd be a temporary presence. But Alfie's feathers were not growing correctly, requiring prolonged care. As Alfie grew and gained strength, she became a part of the family, joining a menagerie of dogs and chickens and making a home for herself in the backyard.
