When did we begin to be as self-centered as we are today? At what point did we expect to have the right to determine our own lives? When did we first ask the question, how can I be free? It all began in the 1790s in a quiet university town in Germany when a group of playwrights, poets, and writers put the self at center stage in their thinking, writing, and their lives.

The thrilling story of the charismatic explorer who Simon Bolivar called "the true discoverer of South America" and the daring expedition that altered the course of science. From 1799 to 1804 German naturalist and adventurer Alexander von Humboldt conducted the first extensive scientific exploration of Latin America.

From the author of the acclaimed The Brother Gardeners, a fascinating look at the founding fathers from the unique and intimate perspective of their lives as gardeners, plantsmen, and farmers. For the founding fathers, gardening, agriculture, and botany were elemental passions, as deeply ingrained in their characters as their belief in liberty for the nation they were creating. These stories reveal a guiding but previously overlooked ideology of the American Revolution.

On June 6, 1761, the world paused to observe a momentous occasion: the first transit of Venus between the earth and the sun in more than a century. Through that observation, astronomers could calculate the size of the solar system - but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Fortunately, transits of Venus occur in pairs: eight years later, the scientists would have another opportunity to succeed.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.

In the 19th century, American meals were about subsistence, not enjoyment. But as a new century approached, appetites broadened, and David Fairchild, a young botanist with an insatiable lust to explore and experience the world, set out in search of foods that would enrich the American farmer and enchant the American eater. Kale from Croatia, mangoes from India, and hops from Bavaria. Peaches from China, avocados from Chile, and pomegranates from Malta. But Fairchild's finds weren't just limited to food.

Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; her TED talks have been viewed by more than 10 million people worldwide. In this, her first book, now available in audio, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths—that trees are not simply the source of timber or pulp, but are a complicated, interdependent circle of life.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

Oaks sustain a complex and fascinating web of wildlife. The Nature of Oaks reveals what is going on in oak trees month by month, highlighting the seasonal cycles of life, death, and renewal. From woodpeckers who collect and store hundreds of acorns for sustenance to the beauty of jewel caterpillars, Tallamy illuminates and celebrates the wonders that occur right in our own backyards. The Nature of Oaks will inspire you to treasure these trees and to act to nurture and protect them.

On January 28, 1742, a ramshackle vessel of patched-together wood and cloth washed up on the coast of Brazil. Inside were thirty emaciated men, barely alive, and they had an extraordinary tale to tell. They were survivors of His Majesty’s Ship the Wager, a British vessel that had left England in 1740 on a secret mission during an imperial war with Spain. While the Wager had been chasing a Spanish treasure-filled galleon known as “the prize of all the oceans,” it had wrecked on a desolate island off the coast of Patagonia.

First published in 1949 and praised in the New York Times Book Review as "full of beauty and vigor and bite", A Sand County Almanac combines some of the finest nature writing since Thoreau with an outspoken and highly ethical regard for America's relationship to the land.

Hailed as "the great nature writer of this generation" (Wall Street Journal), Robert Macfarlane is the celebrated author of books about the intersections of the human and the natural realms. In Underland, he delivers his masterpiece: an epic exploration of the Earth's underworlds as they exist in myth, literature, memory, and the land itself.

It is astonishing that Simón Bolívar, the great Liberator of South America, is not better known in the United States. He freed six countries from Spanish rule, traveled more than 75,000 miles on horseback to do so, and became the greatest figure in Latin American history. His life is epic, heroic, straight out of Hollywood: he fought battle after battle in punishing terrain, forged uncertain coalitions of competing forces and races, lost his beautiful wife soon after they married and died relatively young, uncertain whether his achievements would endure.

A trailblazing account of human history, challenging our most fundamental assumptions about social evolution—from the development of agriculture and cities to the emergence of "the state", political violence, and social inequality—and revealing new possibilities for human emancipation.

A major audiobook about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes. Over the last half a billion years, there have been five mass extinctions, when the diversity of life on Earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs.

When Dr. David Hosack tilled the country's first botanical garden in the Manhattan soil more than 200 years ago, he didn't just dramatically alter the New York landscape; he left a monumental legacy of advocacy for public health and wide-ranging support for the sciences. In melodic prose, historian Victoria Johnson eloquently chronicles Hosack's tireless career to reveal the breadth of his impact. The result is a lush portrait of the man who gave voice to a new, deeply American understanding of the powers and perils of nature.

When young Joseph Banks stepped onto a Tahitian beach in 1769, he hoped to discover Paradise. Inspired by the scientific ferment sweeping through Britain, the botanist had sailed with Captain Cook in search of new worlds. Other voyages of discovery—astronomical, chemical, poetical, philosophical—swiftly follow in Richard Holmes's thrilling evocation of the second scientific revolution.

The compelling story of the effect of Charles Darwin's book On the Origin of Species on a diverse group of American writers, abolitionists, and social reformers, including Henry David Thoreau and Bronson Alcott, in 1860.

When did we begin to be as self-centered as we are today? At what point did we expect to have the right to determine our own lives? When did we first ask the question, how can I be free? It all began in the 1790s in a quiet university town in Germany when a group of playwrights, poets, and writers put the self at center stage in their thinking, writing, and their lives.

In 1839 rumors of extraordinary yet baffling stone ruins buried within the unmapped jungles of Central America reached two of the world's most intrepid travelers. Seized by the reports, American diplomat John Lloyd Stephens and British artist Frederick Catherwood sailed together out of New York Harbor on an expedition into the forbidding rainforests of present-day Honduras, Guatemala, and Mexico. What they found would rewrite the West's understanding of human history.

No cloistered don, this tall, married Englishman was a freethinking intellectual, who practiced nudism and was devoted to a quirky brand of folk dancing. In 1937, while working as a biochemist at Cambridge University, he instantly fell in love with a visiting Chinese student, with whom he began a lifelong affair. He soon became fascinated with China, and his mistress swiftly persuaded the ever-enthusiastic Needham to travel to her home country, where he embarked on a series of extraordinary expeditions to the farthest frontiers of this ancient empire.

In 1856 Paul Du Chaillu marched into the equatorial wilderness of West Africa determined to bag an animal that, according to legend, was nothing short of a monster. When he emerged three years later, the summation of his efforts only hinted at what he'd experienced in one of the most dangerous regions on earth. Armed with an astonishing collection of zoological specimens, Du Chaillu leapt from the physical challenges of the jungle straight into the center of the biggest issues of the time.

Henry David Thoreau has long been an intellectual icon and folk hero. In this strikingly original profile, Michael Sims reveals how the bookish, quirky young man evolved into the patron saint of environmentalism and nonviolent activism. Working from 19th-century letters and diaries, Sims charts Henry’s course from his time at Harvard through the years he spent living in a cabin beside Walden Pond. Sims uncovers a previously hidden Thoreau - the rowdy boy reminiscent of Tom Sawyer, the sarcastic college iconoclast, the devoted son who kept imitating his beloved older brother’s choices in life.

For millennia the location of the Nile River’s headwaters was shrouded in mystery. In the 19th century, there was a frenzy of interest in ancient Egypt. At the same time, European powers sent off waves of explorations intended to map the unknown corners of the globe—and extend their colonial empires.

John Wesley Powell’s first descent of the Colorado River through the Grand Canyon in 1869 counts among the most dramatic chapters in American exploration history. When the Canyon spit out the surviving members of the expedition - starving, battered, and nearly naked - they had accomplished what others thought impossible and finished the exploration of continental America that Lewis and Clark had begun almost 70 years before.

Why didn't the Chinese discover America? Why were people so slow to learn the earth goes around the sun? How and why did we begin to think of "species" of plants and animals? How, when, and why did people begin digging in the earth to learn about the past? How did the study of economics begin? These are but a few of the fascinating questions answered by Dr. Boorstin, Librarian of Congress Emeritus.

Pulitzer Prize winner Wallace Stegner recounts the remarkable career of Major John Wesley Powell, the distinguished ethnologist and geologist who explored the Colorado River, the Grand Canyon, and the homeland of the Southwest Indian tribes. This classic work is a penetrating and insightful study of the Powell’s career, from the beginning of the Powell Survey, in which Powell and his men famously became the first to descend the Colorado River, to his eventual expulsion from the Geological Survey.

In December 1929, in a cave near Peking, a group of anthropologists and archaeologists that included a young French Jesuit priest named Pierre Teilhard de Chardin uncovered a prehuman skull. The find quickly became known around the world as Peking Man and was acclaimed as the missing link between erect hunting apes and our Cro-Magnon ancestors. It also became a provocative piece of evidence in the roiling debate over creationism versus evolution.

At once an incredible adventure narrative and a penetrating biographical portrait, Egan's book tells the remarkable untold story behind Edward Curtis's iconic photographs, following him throughout Indian country from desert to rainforest as he struggled to document the stories and rituals of more than eighty tribes. Even with the backing of Theodore Roosevelt and J.P. Morgan, it took tremendous perseverance. The undertaking changed him profoundly, from detached observer to outraged advocate.

She has been called the female Lawrence of Arabia, which, while not inaccurate, fails to give Gertrude Bell her due. She was at one time the most powerful woman in the British Empire: a nation builder, the driving force behind the creation of modern-day Iraq. Born in 1868 into a world of privilege, Bell turned her back on Victorian society, choosing to read history at Oxford and going on to become an archaeologist, spy, Arabist, linguist, author, poet, photographer, and legendary mountaineer.
