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. This time around, the cataclysm is us. In prose that is at once frank, entertaining, and deeply informed, The New Yorker writer Elizabeth Kolbert tells us why and how human beings have altered life on the planet in a way no species has before. Interweaving research in half a dozen disciplines, descriptions of the fascinating species that have already been lost, and the history of extinction as a concept, Kolbert provides a moving and comprehensive account of the disappearances occurring before our very eyes. She shows that the sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human.

    Keenly aware that the course of the nation's destiny lay westward—and that a "Voyage of Discovery" would be necessary to determine the nature of the frontier—President Thomas Jefferson commissioned Meriwether Lewis to lead an expedition from the Missouri River to the northern Pacific coast and back. From 1804 to 1806, accompanied by co-captain William Clark, the Shoshone guide Sacajawea, and thirty-two men, Lewis mapped rivers, traced the principal waterways to the sea, and established the American claim to the territories of Idaho, Washington, and Oregon. Together the captains kept this journal: a richly detailed record of the flora and fauna they sighted, the native tribes they encountered, and the awe-inspiring landscape they traversed, from their base camp near present-day St. Louis to the mouth of the Columbia River, that has become an incomparable contribution to the literature of exploration and the writing of natural history.

    She is drawn to the Appalachian Trail, a 2175-mile footpath that stretches from Georgia to Maine. Though her friends and family think she's crazy, she sets out alone to hike the trail, hoping it will give her time to think about what she wants to do next. The next four months are the most physically and emotionally challenging of her life. She quickly discovers that thru-hiking is harder than she had imagined: coping with blisters and aching shoulders from the 30-pound pack she carries; sleeping on the hard wooden floors of trail shelters; hiking through endless torrents of rain and even a blizzard. With every step she takes, Jennifer transitions from an over-confident college graduate to a student of the trail, braving situations she never imagined before her thru-hike. The trail is full of unexpected kindness, generosity, and humor. And when tragedy strikes, she learns that she can depend on other people to help her in times of need.

    Outer Hebrides, 600 acres . . . Puffins and seals. Apply . . . ”.In this radiant and powerful book, Adam describes, and relives, his love affair with this enchantingly beautiful property, which he inherited when he was twenty-one. As the islands grew to become the most important thing in his life, they began to offer him more than escape, giving him “sea room”—a sailing term Nicolson uses to mean “the sense of enlargement that island life can give you.”The Shiants—the name means holy or enchanted islands—lie east of the Isle of Lewis in a treacherous sea once known as the “stream of blue men,” after the legendary water spirits who menaced sailors there. Crowned with five-hundred-foot cliffs of black basalt and surrounded by tidal rips, teeming in the summer with thousands of sea birds, they are wild, dangerous, and dramatic—with a long, haunting past. For millennia the Shiants were a haven for those seeking solitude—an eighth-century hermit, the twentieth-century novelist Compton Mackenzie—but their rich, sometimes violent history of human habitation includes much more. Since the Stone Age, families have dwelled on the islands and sailors have perished on their shores. The landscape is soaked in centuries-old tales of restless ghosts and ancient treasure, cradling the heritage of a once productive world of farmers and fishermen.In passionate, keenly precise prose, Nicolson evokes the paradoxes of island life: cut off from the mainland yet intricately bound to it, austere yet fertile, unforgiving yet bewitchingly beautiful.Sea Room does more than celebrate and praise this extraordinary place. It shares with us the greatest gift an island can bestow: a deep, revelatory engagement with the natural world.

    Complications lays bare a science not in its idealized form but as it actually is--uncertain, perplexing, and profoundly human.Complications is a 2002 National Book Award Finalist for Nonfiction.

    A group of young scientists, under the guidance of Dr. George Church, the most brilliant geneticist of our time, works to make fantasy reality by sequencing the DNA of a frozen woolly mammoth harvested from above the Arctic circle, and splicing elements of that sequence into the DNA of a modern elephant. Will they be able to turn the hybrid cells into a functional embryo and bring the extinct creatures to life in our modern world?Along with Church and his team of Harvard scientists, a world-famous conservationist and a genius Russian scientist plan to turn a tract of the Siberian tundra into Pleistocene Park, populating the permafrost with ancient herbivores as a hedge against an environmental ticking time bomb.
