Chimney Swifts, birds that nest and roost in chimneys, have been historically abundant in North America. But by the late 1980s, the number of swifts migrating to North America from the Amazon River Basin had declined. A growing number of people across North America are now constructing nesting towers and conducting Chimney Swift conservation projects in their own communities. With Chimney Swift Towers, concerned bird conservationists have a step-by-step guide to help them create more habitat for these beneficial, insect-eating birds. Chimney Swift experts Paul and Georgean Kyle give directions for building freestanding wooden towers, wooden kiosk towers, masonry towers, and other structures. Included are - design basics, - lists of materials needed, - useful diagrams and photographs, - and detailed instructions on site preparation, tower construction, installation, and maintenance. Anyone with basic woodworking or masonry skills and an interest in wildlife conservation will find this publication helpful. That includes do-it-yourselfers, homeowners involved in creating backyard habitat for wildlife, landscape and structural architects, park and wildscape managers, wildlife management area professionals, nature centers, garden centers, scout troops, and other civic organizations in search of community service projects.

Evolutionary science is not only one of the greatest breakthroughs of modern science, but also one of the most controversial. Perhaps more than any other scientific area, evolutionary science has caused us all to question what we are, where we came from, and how we relate to the rest of the universe. Encyclopedia of Evolution contains more than 200 entries that span modern evolutionary science and the history of its development. This comprehensive volume clarifies many common misconceptions about evolution. For example, many people have grown up being told that the fossil record does not demonstrate an evolutionary pattern, and that there are many missing links. In fact, most of these missing links have been found, and their modern representatives are often still alive today. The biographical entries represent evolutionary scientists within the United States who have had and continue to have a major impact on the broad outline of evolutionary science. The biographies chosen reflect the viewpoints of scientists working within the United States. Five essays that explore interesting questions resulting from studies in evolutionary science are included as well. The appendix consists of a summary of Charles Darwin's Origin of Species, which is widely considered to be the foundational work of evolutionary science and one of the most important books in human history. The five essays include: How much do genes control human behavior?What are the ghosts of evolution?Can an evolutionary scientist be religious?Why do humans die?Are humans alone in the universe

Progress requires the conquest of nature. Or does it? This startling new account overturns conventional interpretations of Marx and in the process outlines a more rational approach to the current environmental crisis. Marx, it is often assumed, cared only about industrial growth and the development of economic forces. John Bellamy Foster examines Marx's neglected writings on capitalist agriculture and soil ecology, philosophical naturalism, and evolutionary theory. He shows that Marx, known as a powerful critic of capitalist society, was also deeply concerned with the changing human relationship to nature. Marx's Ecology covers many other thinkers, including Epicurus, Charles Darwin, Thomas Malthus, Ludwig Feuerbach, P. J. Proudhon, and William Paley. By reconstructing a materialist conception of nature and society, Marx's Ecology challenges the spiritualism prevalent in the modern Green movement, pointing toward a method that offers more lasting and sustainable solutions to the ecological crisis.

MUNICIPAL SOLID WASTE TO ENERGY CONVERSION PROCESSES A TECHNICAL AND ECONOMIC REVIEW OF EMERGING WASTE DISPOSAL TECHNOLOGIES Intended for a wide audience ranging from engineers and academics to decision-makers in both the public and private sectors, Municipal Solid Waste to Energy Conversion Processes: Economic, Technical, and Renewable Comparisons reviews the current state of the solid waste disposal industry. It details how the proven plasma gasification technology can be used to manage Municipal Solid Waste (MSW) and to generate energy and revenues for local communities in an environmentally safe manner with essentially no wastes. Beginning with an introduction to pyrolysis/gasification and combustion technologies, the book provides many case studies on various waste-to-energy (WTE) technologies and creates an economic and technical baseline from which all current and emerging WTE technologies could be compared and evaluated. Topics include: Pyrolysis/gasification technology, the most suitable and economically viable approach for the management of wastes Combustion technology Other renewable energy resources including wind and hydroelectric energy Plasma economics Cash flows as a revenue source for waste solids-to-energy management Plant operations, with an independent case study of Eco-Valley plant in Utashinai, Japan Extensive case studies of garbage to liquid fuels, wastes to electricity, and wastes to power ethanol plants illustrate how currently generated MSW and past wastes in landfills can be processed with proven plasma gasification technology to eliminate air and water pollution from landfills.
