A natural history of the wilderness in our homes, from the microbes in our showers to the crickets in our basements Even when the floors are sparkling clean and the house seems silent, our domestic domain is wild beyond imagination. In Never Home Alone, biologist Rob Dunn introduces us to the nearly 200,000 species living with us in our own homes, from the Egyptian meal moths in our cupboards and camel crickets in our basements to the lactobacillus lounging on our kitchen counters. You are not alone.

Offering innovative ideas for protecting coastlines and cleaning the toxic seas, Scales insists we need more ethical and sustainable fisheries and must prevent the other existential threat of deep-sea mining, which could significantly alter life on earth. Inspiring us all to maintain a sense of awe and wonder at the majesty beneath the waves, she urges us to fight for the better future that still exists for the Anthropocene ocean.

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.

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.

A forester's fascinating stories backed by the latest scientific research illustrate how trees nurture and talk to each other. Are trees social beings? In this international best seller - which has sold more than 320,000 copies in Germany alone - forester and author Peter Wohlleben convincingly makes the case that, yes, the forest is a social network. He draws on groundbreaking scientific discoveries to describe how trees are like human families.

In the tradition of Mountains Beyond Mountains and The Orchid Thief, Stronghold is Tucker Malarkey’s eye-opening account of one of the world’s greatest fly fishermen and his crusade to protect the world’s last bastion of wild salmon. From a young age, Guido Rahr was a misfit among his family and classmates, preferring to spend his time in the natural world. When the salmon runs of the Pacific Northwest began to decline, Guido was one of the few who understood why.

In Bite, zoologist Bill Schutt makes a surprising case: it is teeth that are responsible for the long-term success of vertebrates. The appearance of teeth, roughly half a billion years ago, was an adaptation that allowed animals with backbones, such as fish, amphibians, reptiles, birds, dinosaurs and mammals—including us—to chow down in pretty much every conceivable environment.

When Chris Dombrowski burst onto the literary scene with Body of Water, the book was acclaimed as “a classic” (Jim Harrison) and its author compared with John McPhee. Dombrowski begins the highly anticipated The River You Touch with a question as timely as it is profound: “What does a meaningful, mindful, sustainable inhabitance on this small planet look like in the anthropocene?”

As a graduate student exploring the rain forests of Australia, Meg Lowman realized that she couldn’t monitor her beloved leaves using any of the usual methods. So she put together a climbing kit: she sewed a harness from an old seat belt, gathered hundreds of feet of rope, and found a tool belt for her pencils and rulers. Up she went, into the trees. Forty years later, Lowman remains one of the world’s foremost arbornauts, known as the “real-life Lorax.”

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.

In the mid-1930s, North America's Great Plains faced one of the worst man-made environmental disasters in world history. Donald Worster's classic chronicle of the devastating years between 1929 and 1939 tells the story of the Dust Bowl in ecological as well as human terms. Twenty-five years after his book helped to define the new field of environmental history, Worster shares his more recent thoughts on the subject of the land and how humans interact with it.

Richard Louv's landmark book, Last Child in the Woods, inspired an international movement to connect children and nature. Now Louv redefines the future of human-animal coexistence. Our Wild Calling explores these powerful and mysterious bonds and how they can transform our mental, physical, and spiritual lives, serve as an antidote to the growing epidemic of human loneliness, and help us tap into the empathy required to preserve life on Earth.

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.

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 Last Great Mountain tells the story of the first ascent of Kangchenjunga the third highest but reputedly the hardest mountain in the world. It was an astonishing achievement for a British team led by Everest veteran Charles Evans. Drawing on interviews, diaries and unpublished accounts, Mick Conefrey begins his story in 1905 with the disastrous first attempt on the mountain by a team led by Aleister Crowley, explores the three dramatic German expeditions of the the late 1920s and brings it all to a climax 50 years later with the first ascent by Joe Brown and George Band.

In the tradition of Rachel Carson’s groundbreaking environmental classic Silent Spring, an award-winning entomologist and conservationist explains the importance of insects to our survival and offers a clarion call to avoid a looming ecological disaster of our own making.

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.

Noted transcendentalist Henry David Thoreau spent two years, two months, and two days chronicling his near-isolation in the small cabin he built in the woods near Walden Pond on land owned by his mentor, the father of Transcendentalism, Ralph Waldo Emerson. Immersing himself in nature and solitude, Thoreau sought to develop a greater understanding of society amidst a life of self-reliance and simplicity. Originally published in 1854, Walden remains one of the most celebrated works in American literature.

Based on interviews and advice from leading glacial, ocean, climate, and geographical scientists, and interwoven with personal, historical, and mythological stories, Magnason's On Time and Water is a rich and compelling work of narrative nonfiction that illustrates the reality of climate change - and offers hope in the face of an uncertain future.
