But, after a broken engagement and a broken heart, he desperately needed a change of scenery. The ambitious plan he cooked up went a bit overboard in that department; Knighton set out to visit every single one of America's National Parks, from Acadia to Zion. Leave Only Footprints is the memoir of his year spent traveling across the United States, a journey that yielded his "On the Trail" series, which quickly became one of CBS Sunday Morning's most beloved segments. In this smart, informative, and often hilarious book, he'll share how his journey through these natural wonders, unchanged by man, ended up changing his worldview on everything from God to politics to love and technology. Whether it's waking up early for a naked scrub in an Arkansas bathhouse or staying up late to stargaze along our loneliest highway, Knighton goes behind the scenery to provide an unfiltered look at America. In the tradition of books like A Walk in the Woods or Turn Right at Machu Picchu, this is an irresistible mix of personal narrative and travelogue-some well-placed pop culture references, too-and a must-read for any of the 331 million yearly National Parks visitors.

    Most of Earth’s oxygen is produced by phytoplankton in the sea. These humble, one-celled organisms, rather than the spectacular rain forests, are the true lungs of the planet.• Climate control. Our climate is regulated by the ocean’s currents, winds, and water-cycle activity.Sea Sick is the first book to examine the current state of the world’s oceans — the great unexamined ecological crisis of the planet — and the fact that we are altering everything about them; temperature, salinity, acidity, ice cover, volume, circulation, and, of course, the life within them.Alanna Mitchell joins the crews of leading scientists in nine of the global ocean’s hotspots to see firsthand what is really happening around the world. Whether it’s the impact of coral reef bleaching, the puzzle of the oxygen-less dead zones such as the one in the Gulf of Mexico, or the shocking implications of the changing Ph balance of the sea, Mitchell explains the science behind the story to create an engaging, accessible yet authoritative account.From the Hardcover edition.

    Journalist Elizabeth Royte weaves together her own adventures on Barro Colorado with tales of researchers struggling to parse the intricate workings of a tropical rain forest. As Royte works alongside the scientists � sorting insects, collecting monkey dung, radiotracking fruit bats � she asks: What is the point of such research? Both "moving and satisfying" (Providence Sunday Journal), The Tapir's Morning Bath humanizes the scientists, who are driven by passion and ambition to explore arcane questions even though the world may not have time to wait for the answers.

    As the forerunner of such important books as Annie Dillard's Pilgrim at Tinker Creek, Edward Abbey's Desert Solitaire, and Robert Finch's The Primal Place, this classic work remains as relevant today as it was sixty-five years ago.

    . . A tour de force of a book that begs to be seen as well as to be read."--The Washington Post Book WorldWorld renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. Shadows of Forgotten Ancestors is a thrilling saga that starts with the origin of the Earth. It shows with humor and drama that many of our key traits--self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics--are rooted in the deep past, and illuminated by our kinship with other animals.Sagan and Druyan conduct a breathtaking journey through space and time, zeroing in on critical turning points in evolutionary history, and tracing the origins of sex, altruism, violence, rape, and dominance. Their book culminates in a stunningly original examination of the connection between primate and human traits. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, Shadows of Forgotten Ancestors is a triumph of popular science.
