In the 1970s, he sent two prize students, Tim Plowman and Wade Davis, to follow in his footsteps and unveil the botanical secrets of coca, the notorious source of cocaine, a sacred plant known to the Inca as the Divine Leaf of Immortality.A stunning account of adventure and discovery, betrayal and destruction, One River is a story of two generations of explorers drawn together by the transcendent knowledge of Indian peoples, the visionary realms of the shaman, and the extraordinary plants that sustain all life in a forest that once stood immense and inviolable.

    And yet, we are the safest and healthiest humans in history. Irrational fear seems to be taking over, often with tragic results. For example, in the months after 9/11, when people decided to drive instead of fly—believing they were avoiding risk—road deaths rose by more than 1,500. In this fascinating, lucid, and thoroughly entertaining examination of how humans process risk, journalist Dan Gardner had the exclusive cooperation of Paul Slovic, the world renowned risk-science pioneer, as he reveals how our hunter gatherer brains struggle to make sense of a world utterly unlike the one that made them. Filled with illuminating real world examples, interviews with experts, and fast-paced, lean storytelling, The Science of Fear shows why it is truer than ever that the worst thing we have to fear is fear itself.

    As a member of the Citizen Potawatomi Nation, she embraces the notion that plants and animals are our oldest teachers. In Braiding Sweetgrass, Kimmerer brings these lenses of knowledge together to show that the awakening of a wider ecological consciousness requires the acknowledgment and celebration of our reciprocal relationship with the rest of the living world. For only when we can hear the languages of other beings are we capable of understanding the generosity of the earth, and learning to give our own gifts in return.

    A cognitive anthropologist and psychologist, Scott Atran argues that religion is a by-product of human evolution just as the cognitive intervention, cultural selection, and historical survival of religion is an accommodation of certain existential and moral elements that have evolved in the human condition.

    Much like human families, tree parents live together with their children, communicate with them, and support them as they grow, sharing nutrients with those who are sick or struggling and creating an ecosystem that mitigates the impact of extremes of heat and cold for the whole group. As a result of such interactions, trees in a family or community are protected and can live to be very old. In contrast, solitary trees, like street kids, have a tough time of it and in most cases die much earlier than those in a group.Drawing on groundbreaking new discoveries, Wohlleben presents the science behind the secret and previously unknown life of trees and their communication abilities; he describes how these discoveries have informed his own practices in the forest around him. As he says, a happy forest is a healthy forest, and he believes that eco-friendly practices not only are economically sustainable but also benefit the health of our planet and the mental and physical health of all who live on Earth.

    In 1992, in a remote mountain range, a team of scientists discovered the remains of an unusual animal with exquisite long horns. It turned out to be a living species new to Western science -- a saola, the first large land mammal discovered in fifty years. Rare then and rarer now, a live saola had never been glimpsed by a Westerner in the wild when Pulitzer Prize finalist and nature writer William deBuys and conservation biologist William Robichaud set off to search for it in central Laos. Their team endured a punishing trek up and down white-water rivers and through mountainous terrain ribboned with the snare lines of armed poachers who roamed the forest, stripping it of wildlife. In the tradition of Bruce Chatwin, Colin Thubron, and Peter Matthiessen, The Last Unicorn chronicles deBuys's journey deep into one of the world's most remote places. It's a story rich with the joys and sorrows of an expedition into undiscovered country, pursuing a species as rare and elusive as the fabled unicorn. As is true with the quest for the unicorn, in the end the expedition becomes a search for something more: the essence of wildness in nature, evidence that the soul of a place can endure, and the transformative power of natural beauty.

    It enabled us to migrate out of Africa and to spread as far as Alaska and Australia. Every day, we put one foot in front of the other―yet how many of us know how we do that, or appreciate the advantages it gives us?Neuroscientist Shane O’Mara invites us to marvel at the benefits walking confers on our bodies and brains. From walking’s evolutionary origins, traced back millions of years to life forms on the ocean floor, to new findings from cutting- edge research, he reveals how the brain and nervous system give us the ability to balance, weave through a crowded city, and run our “inner GPS” system. Walking, in turn, spurs our imaginations and boosts our moods. In Praise of Walking illuminates the joys, health benefits, and mechanics of walking―and reminds us to get out of our chairs and discover a happier, healthier, more creative self.

    The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society.This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.

    But in the modern world, the breast is changing. Breasts are getting bigger, arriving earlier, and attracting newfangled chemicals. Increasingly, the odds are stacked against us in the struggle with breast cancer, even among men. What makes breasts so mercurial—and so vulnerable?In this informative and highly entertaining account, intrepid science reporter Florence Williams sets out to uncover the latest scientific findings from the fields of anthropology, biology, and medicine. Her investigation follows the life cycle of the breast from puberty to pregnancy to menopause, taking her from a plastic surgeon’s office where she learns about the importance of cup size in Texas to the laboratory where she discovers the presence of environmental toxins in her own breast milk. The result is a fascinating exploration of where breasts came from, where they have ended up, and what we can do to save them.

    Far less well-known is a much greater catastrophe that took place at the end of the Permian period 251 million years ago: 90 percent of life was destroyed, including saber-toothed reptiles and their rhinoceros-sized prey on land, as well as vast numbers of fish and other species in the sea.This book documents not only what happened during this gigantic mass extinction but also the recent rekindling of the idea of catastrophism. Was the end-Permian event caused by the impact of a huge meteorite or comet, or by prolonged volcanic eruption in Siberia? The evidence has been accumulating through the 1990s and into the new millennium, and Michael Benton gives his verdict at the very end. From field camps in Greenland and Russia to the laboratory bench, When Life Nearly Died involves geologists, paleontologists, environmental modelers, geochemists, astronomers, and experts on biodiversity and conservation. Their working methods are vividly described and explained, and the current disputes are revealed. The implications of our understanding of crises in the past for the current biodiversity crisis are also presented in detail. 46 b/w illustrations.
