That evidence, he argues, shows that 700 million years ago the Earth did indeed freeze over completely, becoming a giant “snowball,” in the worst climatic catastrophe in history. Even more startling is his assertion that, instead of ending life on Earth, this global deep freeze was the trigger for the Cambrian Explosion, the hitherto unexplained moment in geological time when a glorious profusion of complex life forms first emerged from the primordial ooze.In a story full of intellectual intrigue, we follow the irascible but brilliant Hoffman and a supporting cast of intrepid geologists as they scour the planet, uncovering clue after surprising clue. We travel to a primeval lagoon at Shark Bay in western Australia, where dolphins cavort with swimmers every morning at seven and “living rocks” sprout out of the water like broccoli heads; to the desolate and forbidding ice fields of a tiny Arctic archipelago seven hundred miles north of Norway; to the surprising fossil beds that decorate Newfoundland’s foggy and windswept coastline; and on to the superheated salt pans of California’s Death Valley.Through the contours of these rich and varied landscapes Walker teaches us to read the traces of geological time with expert eyes, and we marvel at the stunning feats of resilience and renewal our remarkable planet is capable of. Snowball Earth is science writing at its most gripping and enlightening.

    Memory is not their guide — no one butterfly makes the round trip — but each year somehow find their way to the same fifty acres of forest on the high slopes of Mexico’s Neovolcanic Mountains, and then make the return trip in the spring.In Four Wings and a Prayer, Sue Halpern sets off on an adventure to delve into the secrets behind this extraordinary phenomenon. She visits scientists and butterfly lovers across the country, offering a keenly observed portrait of the monarchs’ migration and of the people for whom they have become a glorious obsession. Combining science, memoir, and travel writing, Four Wings and a Prayer is an absorbing travelogue and a fascinating meditation on a profound mystery of the natural world.

    For millions, the Galápagos Islands represent nature at its most unspoiled, an inviolate place famed for its rare flora and fauna. But soon today’s 30,000 human residents could surpass 50,000. Add invasive species, floods of tourists, and unresolved conflicts between Ecuadorian laws and local concerns, and it’s easy to see why the Galápagos were recently added to UNESCO’s World Heritage in Danger list. Each chapter in this provocative, perceptive book focuses on a specific person or group with a stake in the Galápagos’ natural resources—from tour companies whose activities are often illegal and not always green, to creationist guides who lead tours with no mention of evolution, from fishermen up in arms over lobster quotas, to modern-day pirates who poach endangered marine species. Bassett presents a perspective as readable as it is sensible. Told with wit, passion, and grace, the Galápagos story serves as a miniature model of Earth itself, a perfect example of how an environment can be destroyed-- and what is being done to preserve these islands before it's too late.

    Generating cataclysmic volcanic eruptions and large earthquakes, the hotspot helped lift the Yellowstone Plateau to more than 7,000 feet and pushed the northern Rockies to new heights, forming unusually large glaciers to carve the landscape. It also created the jewel of the U.S. national park system: Yellowstone. Meanwhile, forces stretching apart the western U.S. created the mountainous glory of Grand Teton National Park. These two parks, with their majestic mountains, dazzling geysers, and picturesque hot springs, are windows into the Earth's interior, revealing the violent power of the dynamic processes within. Smith and Siegel offer expert guidance through this awe-inspiring terrain, bringing to life the grandeur of these geologic phenomena as they reveal the forces that have shaped--and continue to shape--the greater Yellowstone-Teton region. Over seventy illustrations--including fifty-two in full color--illuminate the breathtaking beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions wonders. Fascinating and informative, this book affords us a striking new perspective on Earth's creative forces.

    Although it has a long history, the recent discovery (1992) of the body's widespread endocannabinoid system (ECS) has thrust cannabis back into the limelight again as a viable medicine. In 2012 over 2.5 million prescriptions were written for medical marijuana in the United States. CBD and THC are both cannabinoids found in cannabis. However, while THC produces a “high” in the user, CBD does not. And now legal CBD-rich hemp oil is available over-the-counter in all 50 states, without a prescription. It was discovered that the Hemp Family of plants (cannabis, marijuana) is loaded with cannabinoids that stimulate our ECS receptor sites. These sites are found in the brain, organs, glands, connective tissue and immune cells and plays regulatory roles in many physiological processes including appetite, pain-sensation, mood and memory. The primary purpose of this system revolves around maintaining balance in the body. Cannabinoids found in all varieties of cannabis work in harmony with the cannabinoids we naturally produce when our system is functioning properly. It is now coming to light that we may very well be “Endocannabinoid Deficient” and supplementing with Cannabidiol, known as CBD, may provide just what we’re missing to restore optimum health. The health benefits of cannabidiol (CBD) from natural hemp oil is this book's primary focus. It explores the similarities, differences, uses and benefits of hemp, cannabis and medical marijuana along with the interplay of THC and CBD. Their 480 other components are also discussed, such as terpenoids, flavonoids, enzymes, vitamins, etc. Make no mistake about it, the endocannabinoid system, although newly discovered, is just as important as any other bodily system, like the muscular, cardiac, circulatory or digestive system. The ECS requires its own specialized medicine as found in the Hemp Family of plants, which is also known as cannabis, and which includes all strains of marijuana. Here is a list of conditions known and/or being researched that may be helped by cannabinoid therapeutics and supplementation: Acne ADD/ADHD Addiction AIDS ALS (Lou Gehrig's Disease) Alzheimer’s Anorexia Antibiotic Resistance Anxiety Atherosclerosis Arthritis Asthma Autism Bipolar Cancer Colitis/Crohn’s Depression Diabetes Endocrine Disorders Epilepsy/Seizure Fibromyalgia Glaucoma Heart Disease Huntington’s Inflammation Irritable Bowel Kidney Disease Liver Disease Metabolic Syndrome Migraine Mood Disorders Motion Sickness Multiple Sclerosis Nausea Neurodegeneration Neuropathic Pain Obesity OCD Osteoporosis Parkinson’s Prion/Mad Cow Disease PTSD Rheumatism Schizophrenia Sickle Cell Anemia Skin Conditions Sleep Disorders Spinal Cord Injury Stress Stroke/TBI 10% of the proceeds from sales of this book will be donated to the American Cannabis Nurses Association in an effort to bring together nurses, to share, integrate and one day certify nurses in the science of endocannabinoid therapeutics in nursing practice.

    Today’s independent, self-sufficient lobstermen belong to the communities imbued with a European sense of ties between land and people, but threatened by the forces of homogenization spreading up the eastern seaboard.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. Through forgotten wars and rebellions, and with a deep tradition of resistance to interference by people “from away,” Maine’s lobstermen have defended an earlier vision of America while defying the “tragedy of the commons”—the notion that people always overexploit their shared property. Instead, these icons of American individualism represent a rare example of true communal values and collaboration through grit, courage, and hard-won wisdom.

    They have opened frontiers, founded cities, settled borders, and fed billions. They promote life, forge peace, grant power, and can capriciously destroy everything in their path. Even today, rivers remain a powerful global force -- one that is more critical than ever to our future.In Rivers of Power, geographer Laurence C. Smith explores the timeless yet vastly underappreciated relationship between rivers and civilization as we know it. Rivers are of course important in many practical ways (water supply, transportation, sanitation). But the full breadth of their profound influence on the way we live is less obvious. Rivers define and transcend international borders, forcing cooperation between nations. Huge volumes of river water are used to produce energy, raw commodities, and food. Wars, politics, and demography are transformed by their devastating floods. The territorial claims of nations, their cultural and economic ties to each other, and the migrations and histories of their peoples trace back to rivers, river valleys, and the topographic divides they carve upon the world. Beautifully told and expansive in scope, Rivers of Power reveals how and why rivers have so profoundly influenced our civilization, and examines the importance this vast, arterial power holds for our present, past, and future.

    Giving a clear overview of the classification of our natural world-over 6,000 species-Natural History looks at every kingdom of life, from bacteria, minerals, and rocks to fossils to plants and animals. Featuring a remarkable array of specially commissioned photographs, Natural History looks at thousands of specimens and species displayed in visual galleries that take the reader on an incredible journey from the most fundamental building blocks of the world's landscapes, through the simplest of life forms, to plants, fungi, and animals.

    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.

    It's Appendix and Index make it a great reference tool for those interested in plant and animal life around tidepools.

    Gustavus Cheyney Doane, a gifted but tormented cavalryman known as "the man who invented Wonderland"; the ambitious former vigilante leader Nathaniel Langford; scientist Ferdinand Hayden, who brought photographer William Henry Jackson and painter Thomas Moran to Yellowstone; and Gen. Phil Sheridan, Civil War hero and architect of the Indian Wars, who finally succeeded in having the new National Park placed under the protection of the US Cavalry.  George Black's Empire of Shadows is a groundbreaking historical account of the origins of America's majestic national landmark.

    With this astonishing collection of tree portraits, Thomas Pakenham produced a new kind of tree book. The arrangement owed little to conventional botany. The sixty trees were grouped according to their own strong personalities: Natives, Travellers, Shrines, Fantasies and Survivors. From the ancient native trees, many of which are huge and immeasurably old, to the exotic newcomers from Europe, the East and North America, MEETINGS WITH REMARKABLE TREES captures the history and beauty of these entrancing living structures. Common to all these trees is their power to inspire awe and wonder. This is a lovingly researched book, beautifully illustrated with colour photographs, engravings and maps - a moving testimonial to the Earth's largest and oldest living structures.

    In this evocative and lavishly illustrated narrative, Ken Burns and Dayton Duncan delve into the history of the park idea, from the first sighting by white men in 1851 of the valley that would become Yosemite and the creation of the world’s first national park at Yellowstone in 1872, through the most recent additions to a system that now encompasses nearly four hundred sites and 84 million acres.The authors recount the adventures, mythmaking, and intense political battles behind the evolution of the park system, and the enduring ideals that fostered its growth. They capture the importance and splendors of the individual parks: from Haleakala in Hawaii to Acadia in Maine, from Denali in Alaska to the Everglades in Florida, from Glacier in Montana to Big Bend in Texas. And they introduce us to a diverse cast of compelling characters—both unsung heroes and famous figures such as John Muir, Theodore Roosevelt, and Ansel Adams—who have been transformed by these special places and committed themselves to saving them from destruction so that the rest of us could be transformed as well.The National Parks is a glorious celebration of an essential expression of American democracy.

    This project turned into a quest to discover the secrets of the neighborhood’s flora and fauna, and yielded more than names and trivia: Johnson developed a relationship with his nonhuman neighbors.Johnson argues that learning to see the world afresh, like a child, shifts the way we think about nature: Instead of something distant and abstract, nature becomes real—all at once comical, annoying, and beautiful. This shift can add tremendous value to our lives, and it might just be the first step in saving the world.No matter where we live—city, country, oceanside, ormountains—there are wonders that we walk past every day. Unseen City widens the pinhole of our perspective by allowing us to view the world from the high-altitude eyes of a turkey vulture and the distinctly low-altitude eyes of a snail. The narrative allows us to eavesdrop on the comically frenetic life of a squirrel and peer deep into the past with a ginkgo biloba tree. Each of these organisms has something unique to tell us about our neighborhoods and, chapter by chapter, Unseen City takes us on a journey that is part nature lesson and part love letter to the world’s urban jungles. With the right perspective, a walk to the subway can be every bit as entrancing as a walk through a national park.

    He visits Norwegian megafarms that use genetic techniques once pioneered on sheep to grow millions of pounds of salmon a year. He travels to the ancestral river of the Yupik Eskimos to see the only Fair Trade–certified fishing company in the world. He makes clear how PCBs and mercury find their way into seafood; discovers how Mediterranean sea bass went global; challenges the author of Cod to taste the difference between a farmed and a wild cod; and almost sinks to the bottom of the South Pacific while searching for an alternative to endangered bluefin tuna.Fish, Greenberg reveals, are the last truly wild food — for now. By examining the forces that get fish to our dinner tables, he shows how we can start to heal the oceans and fight for a world where healthy and sustainable seafood is the rule rather than the exception.
