The stories we usually tell ourselves about climate change tend to focus on the damage inflicted on human societies by big storms, severe droughts, and rising sea levels. But the most powerful impacts are being and will be felt by the natural world and its myriad species, which are already in the midst of the sixth great extinction. Rising temperatures are fracturing ecosystems that took millions of years to evolve, disrupting the life forms they sustain--and in many cases driving them towards extinction. The natural Eden that humanity inherited is quickly slipping away.

Alone on a small Missouri farm after a thirty-year marriage, Sue Hubbell found a new love—of the winged, buzzing variety. Left with little but the commercial beekeeping and honey-producing business she started with her husband, Hubbell found solace in the natural world. Then she began to write, challenging herself to tell the absolute truth about her life and the things she cared about. Describing the ups and downs of beekeeping from one springtime to the next, A Country Year transports listeners to a different, simpler place.

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.

In The Equations of Life, biologist Charles S. Cockell makes the forceful argument that the laws of physics narrowly constrain how life can evolve, making evolution's outcomes predictable. If we were to find something very much like a lady bug eating something very much like an aphid on a distant planet, we shouldn't be surprised. The forms of life are guided by a limited set of rules, and, as a result, there is a narrow set of solutions to the challenges of existence.

Mark Arax is from a family of Central Valley farmers, a writer with deep ties to the land who has watched the battles over water intensify even as California lurches from drought to flood and back again. In The Dreamt Land, he travels the state to explore the one-of-a-kind distribution system, built in the 1940s, '50s and '60s, that is straining to keep up with California's relentless growth. The Dreamt Land weaves reportage, history and memoir to confront the "Golden State" myth in riveting fashion.

Cutting-edge techniques across biology, chemistry, physics, and geology have transformed our understanding of the deep past, including the discovery of a previously unknown mass extinction. This compelling evidence, revealing a series of environmental crises resulting in the near collapse of life on Earth, illuminates our current dilemmas in exquisite detail.

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 Of Orcas and Men, a marvelously compelling mix of cultural history, environmental reporting, and scientific research, David Neiwert explores an extraordinary species and its occasionally fraught relationship with human beings. Beginning with their role in myth and contemporary culture, Neiwert shows how killer whales came to capture our imaginations and brings to life the often-catastrophic environmental consequences of that appeal.

In this compelling narrative, O'Connor seeks out neuroscientists, anthropologists and master navigators to understand how navigation ultimately gave us our humanity. Biologists have been trying to solve the mystery of how organisms have the ability to migrate and orient with such precision - especially since our own adventurous ancestors spread across the world without maps or instruments. O'Connor goes to the Arctic, the Australian bush and the South Pacific to talk to masters of their environment who seek to preserve their traditions at a time when anyone can use a GPS to navigate.

Who can forget the sense of wonder with which they discovered the creatures of the deep? In this vibrant hymn to the sea, Callum Roberts - one of the world’s foremost conservation biologists - leads listeners on a fascinating tour of mankind’s relationship to the sea, from the earliest traces of water on Earth to the oceans as we know them today. In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life. Like Four Fish and The Omnivore’s Dilemma, The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.

Throughout history, rivers have been our foremost source of fresh water both for agriculture and for individual consumption, but now economists say that by 2025 water scarcity will cut global food production by more than the current U.S. grain harvest. In this groundbreaking book, veteran science correspondent Fred Pearce focuses on the dire state of the world's rivers to provide our most complete portrait yet of the growing world water crisis and its ramifications for us all.

This audiobook explores the deep past and examines the latest knowledge on bison anatomy and physiology, how bison responded to climate change (especially drought), and early bison hunters and pre-contact trade. It also focuses on the era of European contact, in particular the arrival of the horse, and some of the first known instances of over-hunting. By the 19th century, bison reached a "tipping point" as a result of new tanning practices, an early attempt at protective legislation, and ventures to introducing cattle as a replacement stock.

Part guide to the best practice in every aspect of working with this renewable energy source, part meditation on the human instinct for survival, this definitive handbook on the art of chopping, stacking and drying wood in the Scandinavian way has resonated across the world, with more than a million copies sold worldwide.

From the author of The Secret Knowledge of Water and Atlas of a Lost World comes a deeply felt essay collection focusing upon a vivid series of desert icons - a sheet of virga over Monument Valley, white seashells in dry desert sand, boulders impossibly balanced. Craig Childs delves into the primacy of the land and the profound nature of the more-than-human.

Using her expertise in ancient Israelite society and economy as well as in biblical theology, Richter walks listeners through passages familiar and not-so-familiar, showing how significant environmental theology is in the Bible's witness. She then calls Christians to apply that message to today's environmental concerns. Richter is a master Bible scholar. Each chapter in this timely book draws out a biblical mandate about care for the land, for domestic and wild animals, for people at the margins, and more. She is also a master storyteller.

Frank Ledwidge offers a sweeping look at the history of air warfare, introducing the major battles, crises, and controversies where air power has taken center stage and exploring the changes in technology and air power capabilities over time. Considering whether bombing has ever been truly effective, he discusses whether wars can be won from the air and concludes by analyzing whether there is a future for manned air power, or if it is inevitable that drones will dominate 21st-century war in the air.

When Lawrence Anthony learned that the northern white rhino, living in the war-ravaged Congo, was on the very brink of extinction, he knew he had to act. If the world lost the sub-species, it would be the largest land mammal since the woolly mammoth to go extinct. In The Last Rhinos, Anthony recounts his attempts to save these remarkable animals. The demand for rhino horns in the Far East has turned poaching into a dangerous black market that threatens the lives of not just these rare beasts, but also the rangers who protect them.

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.

Not far from Seattle skyscrapers live 150-year-old clams, more than 250 species of fish, and underwater kelp forests as complex as any terrestrial ecosystem. For millennia, vibrant Coast Salish communities have lived beside these waters dense with nutrient-rich foods, with cultures intertwined through exchanges across the waterways. Transformed by settlement and resource extraction, Puget Sound and its future health now depend on a better understanding of the region's ecological complexities.
