The ways of magic are revealed in nature...The secrets are written in meandering streams and drifting clouds, whispered by the roaring ocean and cooling breeze, echoed through caves and rocks and forests. When you draw a heart in the sand, call on the four winds for assistance, or ask the rain to wash away a bad habit, you are practicing earth magic. By working in harmony with nature, we can transform ourselves, our lives, and our world. This tried-and-true guide offers more than one hundred spells, rites, and simple rituals you can perform using the powerful energy of the earth. Scott Cunningham was a greatly respected teacher and one of the most influential members of the modern Craft movement. A practitioner of elemental magic for twenty years, he wrote more than fifty books, including the seminal Wicca: A Guide for the Solitary Practitioner.

When Nature Power was first published twelve years ago, the practice of herbal medicine in Nigeria and in most parts of Africa was identified with witchcraft, sorcery, ritualism, and all sorts of fetish practices. Because herbal medicine was associated with paganism, African Christians secretly patronize traditional healers, and the educated elite and religious figures did not want to be associated in any way with traditional African medicine. Nature Power, like a lonely voice in a wilderness, was written to correct the misconception that African herbal medicine is synonymous with paganism, ritualism, and fetishism. Since its publication, Nature Power has been reprinted more than eight times. It has contributed immensely in changing the attitudes of both the government and Christians toward the practice of herbal medicine. Nature Power has also helped show that health is more than an absence of disease. Health is wholeness of mind, soul, and body. Much of the information in this book is age-old secrets, which herbalists keep close to their chests. I have made them available here so that humanity may profit from them.

An "eye-opening, sometimes alarming, and ultimately inspiring" natural history of rivers and their complex and ancient relationship with human civilization (Elizabeth Kolbert, Pulitzer Prize-winning author of The Sixth Extinction). Rivers, more than any road, technology, or political leader, have shaped the course of human civilization. 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 underappreciated relationship between rivers and civilization as we know it. Rivers are of course important in many practical ways (water supply, transportation, sanitation, etc). But the full breadth of their 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. And as climate change, technology, and cities transform our relationship with nature, new opportunities are arising to protect the waters that sustain us. 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 the future of humanity. "As fascinating as it is beautifully written."---Jared Diamond, Pulitzer Prize-winning author of Guns, Germs, and Steel, Collapse, and Upheaval

Creatine and Androstene: They`re the natural supplements that scored with Mark McGuire--are they help or hype? When Cardinals first baseman Mark McGuire broke baseball records with the most home runs in one season, he was hailed as an outstanding athlete-but he also made news for another reason. McGuire was taking Androstene (a brand-name for androstenedione) and creatine, two natural supplements used to build muscle and enhance athletic performance. But how much can sports supplements improve performance? How safe are they? And how ethical is the use of such supplements in sports? These and many other compelling questions about performance-enhancing supplements are expertly answered here, along with: -The hazards of steroids: both prescription and natural, and how the two compare -How safe it is for children and teens to take sports supplements -An overview of Androstene and other testosterone-enhancing supplements -How the use of amino acids such as creatine aids in performance -Other athletic-enhancing supplements, including antioxidants, vitamins, minerals, and more -Q&As, resources, and organizations of interest Find out the pros and cons of all kinds of performance enhancing sports supplements-culled form the latest research and coaches and athletes themselves-to see if you can safely benefit from these natural power builders.

Walden Pond. The Grand Canyon.Yosemite National Park. Throughout the twentieth century, photographers and filmmakers created unforgettable images of these and other American natural treasures. Many of these images, including the work of Ansel Adams, continue to occupy a prominent place in the American imagination. Making these representations, though, was more than a purely aesthetic project. In fact, portraying majestic scenes and threatened places galvanized concern for the environment and its protection. Natural Visions documents through images the history of environmental reform from the Progressive era to the first Earth Day celebration in 1970, showing the crucial role the camera played in the development of the conservation movement. In Natural Visions, Finis Dunaway tells the story of how visual imagery—such as wilderness photographs, New Deal documentary films, and Sierra Club coffee-table books—shaped modern perceptions of the natural world. By examining the relationship between the camera and environmental politics through detailed studies of key artists and activists, Dunaway captures the emotional and spiritual meaning that became associated with the American landscape. Throughout the book, he reveals how photographers and filmmakers adapted longstanding traditions in American culture—the Puritan jeremiad, the romantic sublime, and the frontier myth—to literally picture nature as a place of grace for the individual and the nation. Beautifully illustrated with photographs by Ansel Adams, Eliot Porter, and a host of other artists, Natural Visions will appeal to a wide range of readers interested in American cultural history, the visual arts, and environmentalism.

This technical book explores current and future applications of solar power as an unlimited source of energy that earth receives every day. Photosynthetic organisms have learned to utilize this abundant source of energy by converting it into high-energy biochemical compounds. Inspired by the efficient conversion of solar energy into an electron flow, attempts have been made to construct artificial photosynthetic systems capable of establishing a charge separation state for generating electricity or driving chemical reactions. Another important aspect of photosynthesis is the CO2 fixation and the production of high energy compounds. Photosynthesis can produce biomass using solar energy while reducing the CO2 level in air. Biomass can be converted into biofuels such as biodiesel and bioethanol. Under certain conditions, photosynthetic organisms can also produce hydrogen gas which is one of the cleanest sources of energy.
