Edelsteine
by Florian NeukirchenWie entstehen Edelsteine? Wo gibt es sie? Und was können wir von ihnen lernen? Bei der Bildung von Smaragd, Rubin, Diamant, Topas oder Opal sind die beteiligten Zutaten und Prozesse so vielfältig wie die Edelsteine selbst. Während beispielsweise die Riesenkristalle eines Pegmatits innerhalb von Tagen wachsen, dauert die Entstehung von Amethystgeoden einige Millionen Jahre. Anschaulich erklärt Florian Neukirchen, wie seltene Elemente angereichert werden und wie es zu ungewöhnlichen Begegnungen zwischen Spurenelementen kommt. Diamanten verdanken wir nicht nur einiges Wissen über den Erdmantel, sondern auch über die Entstehung der ersten Kontinente. Bei ihrer Bildung spielen Redoxreaktionen im Erdmantel eine ähnlich wichtige Rolle wie ungewöhnlich ablaufende Vulkaneruptionen, durch die sie sicher an die Oberfläche gebracht werden, ohne zu verbrennen. Edelsteine erzählen uns manch erstaunliche Geschichte: Wie eine Kapsel, die geheime Dokumente birgt, enthalten sie Informationen über unzugängliche Regionen der Erde aus einer fernen Vergangenheit und sogar aus der Tiefe des Weltalls: In Meteoriten wurden Diamanten gefunden, die sogar älter als das Sonnensystem sind. Granate dienen Forschern als eine Art Thermometer, da sie die Bildungstemperatur eines Gesteins anzeigen. Einige Zirkonkristalle sind die einzigen Zeugen aus der höllisch heißen Frühzeit der Erde, aus der keine Gesteine erhalten sind. Die winzigen Kristalle ermöglichen uns sogar Aussagen über das damalige Klima. Abgerundet wird das Buch mit Informationen über Minen, Märkte und antike Handelsrouten und einem Kapitel über die technische Anwendung und synthetische Herstellung von Edelsteinen.

The Edge: How competition for resources is pushing the world, and its climate, to the brink – and what we can do about it.
by Jonathan MaxwellWe live in a World which, though the origins are long, seems suddenly transformed by economic events way out of our control. In seeking stability, we must acknowledge the seismic scale of the challenge, and understand the devastating impact of global energy inefficiency. Every society, organisation, business, household and individual must put efficiency first - not just to save money and carbon and improve resilience, but to reduce the risk, or effect, of conflict.THE EDGE is a very contemporary look at how the world has been transformed by recent economic events, focusing on climate change, the war in Ukraine, the Chinese economy and the challenges the world faces around inflation, energy, transport, fuel, imports etc. Written from an economist/investor's perspective, with lessons for pretty much every institution challenged by these developments, it is a timely and essential resource authored by a global expert with peerless connections, from major organisations to government insiders, from investors to energy corporations. It will help businesses and economies currently at the mercy of the markets to transition towards sustainability, productivity and prosperity, and help everyone understand the world in 2023.
Edge of Empire: Postcolonialism and the City
by Jane M. JacobsEdge of Empire examines struggles over urban space in three contemporary first world cities in an attempt to map the real geographies of colonialism and postcolonialism as manifest in modern society. From London, the one-time heart of the empire, to Perth and Brisbane, scenes of Aboriginal claims for the sacred in the space of the modern city, Jacobs emphasises the global geography of the local and unravels the spatialised cultural politics of postcolonial processes. Edge of Empire forms the basis for understanding imperialism over space and time, and is a recognition of the unruly spatial politics of race and nation, nature and culture, past and present.
The Edge of Extinction: Travels with Enduring People in Vanishing Lands
by Jules PrettyIn The Edge of Extinction, Jules Pretty explores life and change in a dozen environments and cultures across the world, taking us on a series of remarkable journeys through deserts, coasts, mountains, steppes, snowscapes, marshes, and farms to show that there are many different ways to live in cooperation with nature. From these accounts of people living close to the land and close to the edge emerge a larger story about sustainability and the future of the planet. Pretty addresses not only current threats to natural and cultural diversity but also the unsustainability of modern lifestyles typical of industrialized countries. In a very real sense, Pretty discovers, what we manage to preserve now may well save us later. Jules Pretty's travels take him among the Maori people along the coasts of the Pacific, into the mountains of China, and across petroglyph-rich deserts of Australia. He treks with nomads over the continent-wide steppes of Tuva in southern Siberia, walks and boats in the wildlife-rich inland swamps of southern Africa, and experiences the Arctic with ice fishermen in Finland. He explores the coasts and inland marshes of eastern England and Northern Ireland and accompanies Innu people across the taiga’s snowy forests and the lakes of the Labrador interior. Pretty concludes his global journey immersed in the discrete cultures and landscapes embedded within the American landscape: the small farms of the Amish, the swamps of the Cajuns in the deep South, and the deserts of California. The diverse people Pretty meets in The Edge of Extinction display deep pride in their relationships with the land and are only willing to join with the modern world on their own terms. By the examples they set, they offer valuable lessons for anyone seeking to find harmony in a world cracking under the pressures of apparently insatiable consumption patterns of the affluent.

The Edge of the Sea: Under The Sea-wind / The Sea Around Us / The Edge Of The Sea
by Rachel CarsonFrom the National Book Award–winning author of Silent Spring: An exploration of marine life that takes us into &“a truly extraordinary world&” (The Atlantic Monthly). Known for &“catching the life breath of science on the still glass of poetry,&” nature writer and marine biologist Rachel Carson is an icon of environmentalism, and her first love was the sea (Time). In this book, she explores rocky shores, sandy beaches, and coral reefs, leading us into unknown worlds to catch the evanescent beauty of a tide pool and tell the story of a grain of sand, and conveys the true complexity, beauty, and wonder of marine life, both animals and plants. With an introduction by Sue Hubbell, author of A Country Year, and illustrations by Bob Hines, The Edge of the Sea serves as both a field guide and a pleasurable, enlightening read. &“It is a truly extraordinary world which Miss Carson vividly unfolds to us . . . a world full of marvels such as the tiny periwinkle, which has 3,500 teeth, and the sea pansy, which has responded to the struggle for survival by turning itself from an individual into a colony.&” —The Atlantic Monthly
Edges, Fringes, Frontiers: Integral Ecology, Indigenous Knowledge and Sustainability in Guyana (Environmental Anthropology and Ethnobiology #23)
by Thomas HenfreyBased on an ethnographic account of subsistence use of Amazonian forests by Wapishana people in Guyana, Edges, Frontiers, Fringes examines the social, cultural and behavioral bases for sustainability and resilience in indigenous resource use. Developing an original framework for holistic analysis, it demonstrates that flexible interplay among multiple modes of environmental understanding and decision-making allows the Wapishana to navigate social-ecological complexity successfully in ways that reconcile short-term material needs with long-term maintenance and enhancement of the resource base.
Ediacaran-Paleozoic Rock Units of Egypt: Their Correlation with Adjacent Countries and Their Depositional Environments (Earth and Environmental Sciences Library)
by Mohamed Abdel KhalifaThis book presents the following geological contributions in Ediacaran and Paleozoic rocks. 1) It introduces four new rock units for the first time, the Ediacaran El Urf Formation (volcanoclastic sediments in the central Eastern Desert), the Ediacaran Abu Haswa Formation (stromatolitic dolostone in southwestern Sinai), the Early Permian Wadi Dome Formation (mixed clastics and carbonates in the west of Suez Gulf) and the Early Permian Misawag Formation (in the subsurface, northwestern Desert), 2) making correlation of the Ediacaran rock units with the corresponding rock units in Libya, Jordan, Iraq and Saudi Arabia, 3) linking the exposed Paleozoic rock units with their equivalent rock units in subsurface in northwestern desert, 4) correlating the Paleozoic rock units with the equivalent rock units in adjacent countries, e. g. Libya, Jordan, Iraq and Saudi Arabia, 5) manifesting the possible depositional environments of the Ediacaran and Paleozoic rock units. Additionally, it offers an important unique geological information about the Ediacaran and Paleozoic rock units in Egypt. It unifies the nomenclature of Paleozoic rock units that take numerous names for the same geological time. It obsoletes the formation names that do not follow the rules of the North American stratigraphic code (1983) for rock units’ nomenclature. It provides the target audience illustrations, e.g. field photographs for the exposed rock units that save efforts and time for audience (undergraduate, post-graduate, researchers and professional) to reach to the original localities of each rock units. It provides the audience with schematic diagrams that exhibit the link between the exposed and subsurface rock units all over the Egyptian territory. It describes the following topics of each rock unit: definition, stratigraphic contact, lithological characteristics, faunal and floral associations that are used for the identification of the possible age, correlation with corresponding rock units in adjacent countries, e.g. Libya, Jordan, Iraq and Saudi Arabia and the possible depositional environments for each rock units. The book is a fundamental source of an updated version of the information in the field to the undergraduate, graduate, researchers, professional, practitioners and policy planning elsewhere.
Edible Alliums: Botany, Production and Uses (Botany, Production and Uses)
by Haim D. Rabinowitch Brian ThomasAllium crops include more than 30 species, many of which (for e.g. onions, shallots, garlic, leeks, bunching onions, and chives) are of economic importance.

Edible Plants: A Photographic Survey of the Wild Edible Botanicals of North America
by Jimmy FikeFor over a decade, artist Jimmy Fike traveled across the continental United States in an epic effort to photograph wild edible flora. Edible Plants is the culmination of that journey, featuring over 100 photographs that Fike has selectively colorized to highlight the comestible part of the plant. While the images initially appear to be scientific illustrations or photograms from the dawn of photography when plants were placed directly on sensitized paper and exposed under the sun, a closer look reveals, according to Liesl Bradner of the Los Angeles Times, "haunting [and] eerily beautiful" photographs. Beyond instilling wonder, Fike's contemporary, place-based approach to landscape photography emphasizes our relationship to the natural world, reveals food sources, and encourages environmental stewardship. His clever and beautiful method makes it easy to identify both the specimen and its edible parts and includes detailed descriptions about the plant's wider purposes as food and medicine.Sumptuously illustrated and delightfully informative, Edible Plants is the perfect gift for anyone curious about unlocking the secrets of native North American plants.
