With this book he offers a comprehensive, accessible guide to today's complex energy issues--how to think clearly and logically about what is possible and what is desirable in our energy future.After a century of unprecedented production growth, technical innovation, and expanded consumption, the world faces a number of critical energy challenges arising from unequal resource distribution, changing demand patterns, and environmental limitations. The fundamental message of Energy at the Crossroads is that our dependence on fossil fuels must be reduced not because of any imminent resource shortages but because the widespread burning of oil, coal, and natural gas damages the biosphere and presents increasing economic and security problems as the world relies on more expensive supplies and Middle Eastern crude oil.Smil begins with an overview of the twentieth century's long-term trends and achievements in energy production. He then discusses energy prices, the real cost of energy, and energy linkages--the effect energy issues have on the economy, on quality of life, on the environment, and in wartime. He discusses the pitfalls of forecasting, giving many examples of failed predictions and showing that unexpected events can disprove complex models. And he examines the pros and cons not only of fossil fuels but also of alternative fuels such as hydroenergy, biomass energy, wind power, and solar power. Finally, he considers the future, focusing on what really matters, what works, what is realistic, and which outcomes are most desirable.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    Linderman, the well-known western writer who had befriended him. Plenty-coups is a classic account of the nomadic, spiritual, and warring life of Plains Indians before they were forced onto reservations. Plenty-coups tells of the great triumphs and struggles of his own life: his powerful medicine dreams, marriage, raiding and counting coups against the Lakotas, fighting alongside the U.S. Army, and the death of General Custer. This new edition allows readers to appreciate more fully the accomplishments and rich legacy of Plenty-coups. A previously unpublished essay by Linderman tells of his meeting and working with the chief. An introduction by Phenocia Bauerle and Barney Old Coyote Jr., both members of the Crow Nation, speaks to the enduring importance of Plenty-coups for the Crow people in the twenty-first century; an afterword by Timothy P. McCleary, also of the Crow Nation, highlights the pivotal role Plenty-coups played during the early reservation years after the buffalo had gone; an essay by Celeste River examines the special relationship between the old chief and Linderman; a map of Plenty-coups's world highlights places named in the story; a glossary of Crow words and concepts found in the story draws upon the latest orthographic standards and contemporary translation; and a photo gallery showcases both Plenty-coups at different stages of his life and unforgettable scenes of his world.

    This dazzling new biography celebrates his extraordinary life.Davidson tells the whole, rich story of Voltaire`s life (1694-1778): his early imprisonment in the Bastille; exile in England and his mastery of English; an obsession with money, of which he made a huge amount; a scandalous love life; his infatuation with Frederick the Great; a long exile on the borders of Switzerland; his passion for watch-making; his human rights campaigns and his triumphant return to Paris to die there as celebrity extraordinaire. Throughout all of this, Voltaire's life was always informed by two things: a belief in the essential value of toleration in the face of fanaticism; and in the right of every man to think and say what he liked. It is rare to have such a vivid portrait of a great man.

    That is a well-known period in history, when titans like Andrew Carnegie, John D. Rockefeller, and J. P. Morgan walked the earth.But as Charles R. Morris shows us, the platform for that spectacular growth spurt was built in the first half of the century. By the 1820s, America was already the world's most productive manufacturer and the most intensely commercialized society in history. The War of 1812 jump-started the great New England cotton mills, the iron centers in Connecticut and Pennsylvania, and the forges around the Great Lakes. In the decade after the War, the Midwest was opened by entrepreneurs. In this book, Morris paints a vivid panorama of a new nation buzzing with the work of creation. He also points out the parallels and differences in the nineteenth century American/British standoff and that between China and America today.

    Oceans cover two-thirds of the earth's surface with an average depth of more than two miles--yet humans had never ventured more than a few hundred feet below the waves. One of the great scientific and archaeological feats of our time has been finally to cast light on the eternal darkness of the deep sea. This is the story of that achievement, told by the man who has done more than any other to make it possible: Robert Ballard.Ballard discovered the wreck of the Titanic. He led the teams that discovered hydrothermal vents and black smokers--cracks in the ocean floor where springs of superheated water support some of the strangest life-forms on the planet. He was a diver on the team that explored the mid-Atlantic ridge for the first time, confirming the theory of plate tectonics. Today, using a nuclear submarine from the U.S. Navy, he's exploring the ancient trade routes of the Mediterranean and the Black Sea for the remains of historic vessels and their cargo. In this book, he combines science, history, spectacular illustrations, and first-hand stories from his own expeditions in a uniquely personal account of how twentieth-century explorers have pushed back the frontiers of technology to take us into the midst of a world we could once only guess at.Ballard begins in 1930 with William Beebe and Otis Barton, pioneers of the ocean depths who made the world's first deep-sea dives in a cramped steel sphere. He introduces us to Auguste and Jacques Piccard, whose Bathyscaphdescended in 1960 to the lowest point on the ocean floor. He reviews the celebrated advances made by Jacques Cousteau. He describes his own major discoveries--from sea-floor spreading to black smokers--as well as his technical breakthroughs, including the development of remote-operated underwater vehicles and the revolutionary search techniques that led to the discovery and exploration of the Titanic, the Nazi battleship Bismarck, ancient trading vessels, and other great ships.Readers will come away with a richer understanding of history, earth science, biology, and marine technology--and a new appreciation for the remarkable men and women who have explored some of the most remote and fascinating places on the planet.
