The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of “Beaver Believers”―including scientists, ranchers, and passionate citizens―recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them. From the Nevada deserts to the Scottish highlands, Believers are now hard at work restoring these industrious rodents to their former haunts. Eager is a powerful story about one of the world’s most influential species, how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. Ultimately, it’s about how we can learn to coexist, harmoniously and even beneficially, with our fellow travelers on this planet.

    But as Ocean Guardian founder William McKeever reveals, sharks are evolutionary marvels essential to maintaining a balanced ecosystem. We can learn much from sharks, he argues, and our knowledge about them continues to grow. The first book to reveal in full the hidden lives of sharks, Emperors of the Deep examines four species—Mako, Tiger, Hammerhead, and Great White—as never before, and includes fascinating details such as:Sharks are 50-million years older than trees;Sharks have survived five extinction level events, including the one that killed off the dinosaurs;Sharks have electroreception, a sixth-sense that lets them pick up on electric fields generated by living things;Sharks can dive 4,000 feet below the surface;Sharks account for only 6 human fatalities per year, while humans kill 100 million sharks per year.McKeever goes back through time to probe the shark’s pre-historic secrets and how it has become the world’s most feared and most misunderstood predator, and takes us on a pulse-pounding tour around the world and deep under the water’s surface, from the frigid waters of the Arctic Circle to the coral reefs of the tropical Central Pacific, to see sharks up close in their natural habitat. He also interviews ecologists, conservationists, and world-renowned shark experts, including the founders of Greenpeace’s Rainbow Warrior, the head of the Massachusetts Shark Research Program, and the self-professed “last great shark hunter.”At once a deep-dive into the misunderstood world of sharks and an urgent call to protect them, Emperors of the Deep celebrates this wild species that hold the key to unlocking the mysteries of the ocean—if we can prevent their extinction from climate change and human hunters.

    Traveling through the dizzying expanse of geologic time—from prehistoric art in Norwegian sea caves, to the blue depths of the Greenland ice cap, to a deep-sunk "hiding place" where nuclear waste will be stored for 100,000 years to come—Underland takes us on an extraordinary journey into our relationship with darkness, burial, and what lies beneath the surface of both place and mind.Global in its geography and written with great lyricism, Underland speaks powerfully to our present moment. At once ancient and urgent, this is a book that will change the way you see the world.

    Throughout these adventures, Rinella found himself contemplating his own place among the 14,000 years’ worth of buffalo hunters in North America, as well as the buffalo’s place in the American experience. At the time of the Revolutionary War, North America was home to approximately 40 million buffalo, the largest herd of big mammals on the planet, but by the mid-1890s only a few hundred remained. Now that the buffalo is on the verge of a dramatic ecological recovery across the West, Americans are faced with the challenge of how, and if, we can dare to share our land with a beast that is the embodiment of the American wilderness. American Buffalo is a narrative tale of Rinella’s hunt. But beyond that, it is the story of the many ways in which the buffalo has shaped our national identity. Rinella takes us across the continent in search of the buffalo’s past, present, and future: to the Bering Land Bridge, where scientists search for buffalo bones amid artifacts of the New World’s earliest human inhabitants; to buffalo jumps where Native Americans once ran buffalo over cliffs by the thousands; to the Detroit Carbon works, a “bone charcoal” plant that made fortunes in the late 1800s by turning millions of tons of buffalo bones into bone meal, black dye, and fine china; and even to an abattoir turned fashion mecca in Manhattan’s Meatpacking District, where a depressed buffalo named Black Diamond met his fate after serving as the model for the American nickel. Rinella’s erudition and exuberance, combined with his gift for storytelling, make him the perfect guide for a book that combines outdoor adventure with a quirky blend of facts and observations about history, biology, and the natural world. Both a captivating narrative and a book of environmental and historical significance, American Buffalo tells us as much about ourselves as Americans as it does about the creature who perhaps best of all embodies the American ethos.

    A Papua New Guinean elder shoves off in his hand-carved canoe, ready to summon a shark with ancient magic. A scientist finds a rare shark in Indonesia and forges a deal with villagers so it and other species can survive.In this eye-opening adventure that spans the globe, Juliet Eilperin investigates the fascinating ways different individuals and cultures relate to the ocean’s top predator. Along the way, she reminds us why, after millions of years, sharks remain among nature’s most awe-inspiring creatures.From Belize to South Africa, from Shanghai to Bimini, we see that sharks are still the object of an obsession that may eventually lead to their extinction. This is why movie stars and professional athletes go shark hunting in Miami and why shark’s fin soup remains a coveted status symbol in China. Yet we also see glimpses of how people and sharks can exist alongside one another: surfers tolerating their presence off Cape Town and ecotourists swimming with sharks that locals in the Yucatán no longer have to hunt.With a reporter’s instinct for a good story and a scientist’s curiosity, Eilperin offers us an up-close understanding of these extraordinary, mysterious creatures in the most entertaining and illuminating shark encounter you’re likely to find outside a steel cage.

    The book documents the adverse environmental effects caused by the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly.The book appeared in September 1962 and the outcry that followed its publication forced the banning of DDT and spurred revolutionary changes in the laws affecting our air, land, and water. Carson’s book was instrumental in launching the environmental movement.

    Why is the sky dark at night? Is it possible to build a shrink-ray gun? If there is antimatter, can there be antipeople? Why are past, present, and future our only options? Are time and space like a butterfly's wings?No one but Dave Goldberg, the coolest nerd physicist on the planet, could give a hyper drive tour of the universe like this one. Not only does he answer the questions your stoner friends came up with in college, but he also reveals the most profound discoveries of physics with infectious, Carl Sagan–like enthusiasm and accessibility.Goldberg’s narrative is populated with giants from the history of physics, and the biggest turns out to be an unsung genius and Nazi holocaust escapee named Emmy Noether—the other Einstein. She was unrecognized, even unpaid, throughout most of her career simply because she was a woman. Nevertheless, her theorem relating conservation laws to symmetries is widely regarded to be as important as Einstein’s notion of the speed of light. Einstein himself said she was “the most significant creative mathematical genius thus far produced since the higher education of women began.”Symmetry is the unsung great idea behind all the big physics of the last one hundred years—and what lies ahead. In this book, Goldberg makes mindbending science not just comprehensible but gripping. Fasten your seat belt.

    So little, in fact, that scientists and philosophers have, for centuries, been obsessed with what has become known as the “eel question”: Where do eels come from? What are they? Are they fish or some other kind of creature altogether? Even today, in an age of advanced science, no one has ever seen eels mating or giving birth, and we still don’t understand what drives them, after living for decades in freshwater, to swim great distances back to the ocean at the end of their lives. They remain a mystery.Drawing on a breadth of research about eels in literature, history, and modern marine biology, as well as his own experience fishing for eels with his father, Patrik Svensson writes a book about this unusual animal. In The Book of Eels, we meet renowned historical thinkers, from Aristotle to Sigmund Freud to Rachel Carson, for whom the eel was a singular obsession. And we meet the scientists who spearheaded the search for the eel’s point of origin, including Danish marine biologist Johannes Schmidt, who led research efforts in the early twentieth century, catching thousands upon thousands of eels, in the hopes of proving their birthing grounds in the Sargasso Sea.Blending memoir and nature writing, Svensson’s journey to understand the eel becomes an exploration of the human condition that delves into overarching issues about our roots and destiny, both as humans and as animals, and, ultimately, how to handle the biggest question of all: death.

    Thompson digs into the science, politics, and greed behind the 2015 Gold King Mine disaster, and unearths a litany of impacts wrought by a century and a half of mining, energy development, and fracking in southwestern Colorado. Amid these harsh realities, Thompson explores how a new generation is setting out to make amends.As shocking and heartbreaking as the Gold King spill and its aftermath may be, it's merely the tip of the proverbial iceberg. The disaster itself was the climax of the long and troubled story of the Gold King mine, staked by a Swedish immigrant back in 1887. And it was only the most visible manifestation of a slow-moving, multi-faceted environmental catastrophe that had been unfolding here long before the events of August 5, 2015.Jonathan Thompson is a native Westerner with deep roots in southwestern Colorado. He has been an environmental journalist focusing on the American West since he signed on as reporter and photographer at the Silverton Standard & the Miner newspaper in 1996. He has worked and written for High Country News for over a decade, serving as editor-in-chief from 2007 to 2010. He was a Ted Scripps fellow in environmental journalism at the University of Colorado in Boulder, and in 2016 he was awarded the Society of Environmental Journalists' Outstanding Beat Reporting, Small Market. He currently lives in Bulgaria with his wife Wendy and daughters Lydia and Elena.

    Americans eat more bananas than apples and oranges combined. In others parts of the world, bananas are what keep millions of people alive. But for all its ubiquity, the banana is surprisingly mysterious; nobody knows how bananas evolved or exactly where they originated. Rich cultural lore surrounds the fruit: In ancient translations of the Bible, the 'apple' consumed by Eve is actually a banana (it makes sense, doesn't it?). Entire Central American nations have been said to rise and fall over the banana. But the biggest mystery about the banana today is whether it will survive. A seedless fruit with a unique reproductive system, every banana is a genetic duplicate of the next, and therefore susceptible to the same blights. Today's yellow banana, the Cavendish, is increasingly threatened by such a blight -- and there's no cure in sight. Banana combines a pop-science journey around the globe, a fascinating tale of an iconic American business enterprise, and a look into the alternately tragic and hilarious banana subculture (one does exist) -- ultimately taking us to the high-tech labs where new bananas are literally being built in test tubes, in a race to save the world's most beloved fruit.

    MacKinnon realized the grassland he grew up on was not the pristine wilderness he had always believed it to be. Instead, his home prairie was the outcome of a long history of transformation, from the disappearance of the grizzly bear to the introduction of cattle. What remains today is an illusion of the wild--an illusion that has in many ways created our world. In 3 beautifully drawn parts, MacKinnon revisits a globe exuberant with life, where lions roam North America and 20 times more whales swim in the sea. He traces how humans destroyed that reality, out of rapaciousness, yes, but also through a great forgetting. Finally, he calls for an "age of restoration," not only to revisit that richer and more awe-filled world, but to reconnect with our truest human nature. MacKinnon never fails to remind us that nature is a menagerie of marvels. Here are fish that pass down the wisdom of elders, landscapes still shaped by "ecological ghosts," a tortoise that is slowly remaking prehistory. "It remains a beautiful world," MacKinnon writes, "and it is its beauty, not its emptiness, that should inspire us to seek more nature in our lives."
