Oaxaca Journal is Sacks' spellbinding account of his trip with a group of fellow fern enthusiasts to the beautiful, history-steeped province of Oaxaca, Mexico.

Erik Larson dépeint une nouvelle tragédie américaine, s’intéressant cette fois à la folie des hommes qui pensent pouvoir maîtriser les lois de la nature, et au combat héroïque d’Isaac Cline, coupable d’une erreur fatale qu’il paiera au prix fort.

The Space Age began just as the struggle for civil rights forced Americans to confront the long and bitter legacy of slavery, discrimination, and violence against African Americans. Presidents John F. Kennedy and Lyndon Johnson utilized the space program as an agent for social change, using federal equal employment opportunity laws to open workplaces at NASA and NASA contractors to African Americans while creating thousands of research and technology jobs in the Deep South to ameliorate poverty.

North America was not empty nor were its inhabitants savages when Europeans arrived in 1492. Quite the opposite, North America was thickly populated by indigenous people who lived in clean cities, had a thriving economy, and transformed the landscape into bountiful productivity. Forgotten Landscapes reveals the incredible extent to which Native Americans manipulated and shaped their surrounding environs through agricultural practices and urban engineering, resulting in one of the most prosperous civilizations of their time.

In the tradition of William Warner's Beautiful Swimmers, veteran journalist Colin Woodard (author of American Character: A History of the Epic Struggle Between Individual Liberty and the Common Good) traces the history of the rugged fishing communities that dot the coast of Maine and the prized crustacean that has long provided their livelihood.

More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology.

In The Gospel of Kindness, Janet M. Davis explores the broad cultural and social influence of the American animal welfare movement at home and overseas from the Second Great Awakening to the Second World War. Dedicated primarily to laboring animals at its inception in an animal-powered world, the movement eventually included virtually all areas of human and animal interaction.

From the colonial era through the mid-twentieth century, America's flocks played a key role in the nation's development. Furthermore, much consternation centered around the sheep the United States lacked, so that dependency on foreign wool became a full-blown crisis in wartime. But more than just providers of wool, sheep were valued for their meat, for their byproducts after slaughter, and even for their efficiency at lawn maintenance.

The naturalist, author, and advocate for preservation, John Muir (1838-1914) was also known as "John of the Mountains" and "Father of the National Parks". In the spring of 1869, John Muir was looking for ways to fund his explorations of California’s Central Valley region, when a ranch owner offered him a job herding sheep in the Sierra Nevada. In The Yosemite, Muir chronicled his experiences of the beautiful wilderness in appealingly descriptive prose. The audiobook is a treasure trove of portrayals of the shifting phases of the year in Yosemite.

In this fresh and powerful work of environmental history, Martin Doyle explores how rivers have often been the source of arguments at the heart of the American experiment - over federalism, taxation, regulation, conservation, and development. Doyle tells the epic story of America and its rivers, from the US Constitution's roots in interstate river navigation, the origins of the Army Corps of Engineers, the discovery of gold in 1848, and the construction of the Hoover Dam and the TVA during the New Deal, to the failure of the levees in Hurricane Katrina.

The Tensaw River introduces one of the American South's richest and most fertile natural features. Author Mike Bunn is director of Historic Blakeley State Park, which is nestled in a prominent bend of the majestic Tensaw River.

Countering the conventional narrative that Florida's tourism industry suffered during the Great Depression, this book shows that the 1930s were the starting point for much that characterizes modern Florida's tourism. David Nelson argues that state and federal government programs designed to reboot the economy during this decade are crucial to understanding the state today.

The chilling tome that launched an entire genre of books about the often gruesome but always tragic ways people have died in our national parks, this updated edition of the classic includes calamities in Yellowstone from the past sixteen years, including the infamous grizzly bear attacks in the summer of 2011 as well as a fatal hot springs accident in 2000. In these accounts, written with sensitivity as cautionary tales about what to do and what not to do in one of our wildest national parks, Whittlesey recounts deaths ranging from tragedy to folly.

From 1907 to 1967, a network of reservoirs and aqueducts was built across more than one million acres in upstate New York, including Greene, Delaware, Sullivan, and Ulster Counties. This feat of engineering served to meet New York City's ever-increasing need for water, sustaining its inhabitants and cementing it as a center of industry. West of the Hudson, it meant that twenty-six villages, with their farms, forest lands, orchards, and quarries, were bought for a fraction of their value, demolished, and submerged, profoundly altering ecosystems in ways we will never fully appreciate.

North Georgia has more than forty lakes, and not one is natural. The state's controversial decision to dam the region's rivers for power and water supply changed the landscape forever.

With A Furious Sky, Eric Jay Dolin has created a vivid, sprawling account of our encounters with hurricanes, from the nameless storms that threatened Columbus's New World voyages to the destruction wrought in Puerto Rico by Hurricane Maria. Weaving a story of shipwrecks and devastated cities, of heroism and folly, Dolin introduces a rich cast of unlikely heroes and puts us in the middle of the most devastating storms of the past, none worse than the Galveston Hurricane of 1900, which killed at least 6,000 people, the highest toll of any natural disaster in American history.

As the ongoing Flint water crisis marks its tenth anniversary, Chariton reveals shocking new evidence of the major government cover-up that resulted in the poisoning of Flint—and shatters what you think you know about what caused the water crisis.

Jamie Sayen approaches the story of northern New England's undeveloped forests from the viewpoints of the previously unheard: the forest and the nonhuman species it sustains, the First Peoples, and, in more recent times, the disenfranchised human voices of the forest, including those of loggers, mill workers, and citizens who, like Henry David Thoreau, wish to speak a kind word for nature.

Our lives are built around businesses that connect far-flung rural places to urban centers and global destinations. This "country capitalism" that proved successful in the US South has made it possible to satisfy our demands at the click of a button, but each click comes with hidden environmental costs.

For two years, Scots-born John Muir lived in a small cabin along the Yosemite creek, observing the valley's natural beauty and reading Emerson under the stars. The experience forged a lifelong affinity with the site, which would result in its establishment as a national park in 1890. Originally written as a guidebook to the park, The Yosemite describes every aspect of wildlife and landscape that one might encounter there.
