Cities of Tomorrow is a critical history of planning in theory and practice in the twentieth century, as well as of the social and economic problems and opportunities that gave rise to it. Trenchant, perceptive, global in coverage, this book is an unrivalled account of its crucial subject. The third edition of Cities of Tomorrow is comprehensively revised to take account of abundant new literature published since its original appearance, and to view the 1990s in historical perspective. This is the definitive edition, reviewing the development of the modern planning movement over the entire span of the twentieth century.

“The hope for the future depends on teaching current and future students the analytical and critical thinking skills for dealing with the most critical problems. My own hope is for this book to be read by everyone, even those outside the field of environmental education. Read this book, read it again, share it widely, and do something - anything - to help our needy and wounded planet."-Marc Bekoff, author of The Animal Manifesto: Six Reasons For Expanding Our Compassion Footprint "Saylan and Blumstein provide a compelling vision of what can be, and what should be, if we have the courage to open our eyes and the boldness to act.”-Peter Saundry, Ph.D., Executive Director of the National Council for Science and the Environment “A clarion call to incorporate environmental education in all grades K-12, across all academic disciplines, in order to produce future generations of environmental stewards."-Mark Gold, President, Heal The Bay "We need a sea change in the educational system. After all, if we can teach schoolchildren that vandalism is wrong, why can we not teach them that environmental destruction is wrong? This book is a haunting call to action. A beautifully written manifesto that gets it right."-Ron Swaisgood, Director of Applied Animal Ecology, Institute for Conservation Research, San Diego Zoo Global “The greatest threat to the future of all species on the planet is the huge gap between what is understood about global climate change by the scientific community and what is known about climate change by the people who need to know -- the public. The sound prescriptions in this book need to be read now. We are running out of time.”-Dr. James Hansen, world-renowned climatologist and author of Storms of My Grandchildren: The Truth About the Coming Climate Catastrophe and Our Last Chance to Save Humanity “Environmental education is a disaster and educating the public on environmental issues is the greatest challenge facing humanity today. This book will help us understand why we are headed toward the collapse of civilization, and more important, how to fix it. Packed with sound science, useful information, and brilliant ideas, it is a book we must read, and give, to our local school boards and principals nationwide. Our children will thank us."-Paul R. Ehrlich, author of The Population Bomb and Humanity on a Tightrope

As the world's largest industry, tourism has the potential to bring about substantial environmental and socio-economic improvements. This document translates Agenda 21 into a programme of action for the industry.

"In this unique collaboration, naturalists Gary Nabhan and Stephen Trimble investigate how children come to care deeply about the natural world. They ask searching questions about what may happen to children denied exposure to wild places - a reality for more children today than at any time in human history." "The authors remember pivotal events in their own childhood that led each to a life-long relationship with the land: Nabhan's wanderings in the wasteland of steel mills and power plants of Gary, Indiana, and in the Indiana Dunes; Trimble's travels in the West with a geologist father. They tell stories of children learning about wild places and creatures in settings ranging from cities and suburbs to isolated Nevada sheep ranches to Native American communities in the Southwest and Mexico." "The Geography of Childhood draws insights from fields as various as evolutionary biology, child psychology, education, and ethnography. The book urges adults to rethink our children's contact with nature. Small children have less need for large-scale wilderness than for a garden, gully, or field to create a crucial tie to the natural world. Nabhan suggests that traditional wilderness-oriented rites of passage may help cure the alienation of adolescence: "Those who as adolescents fail to pass through such rites remain in an arrested state of immaturity for the remainder of their lives." Trimble's fatherhood leads him to question how we grant different freedoms to girls and boys in their exploration of nature - and how this bias powerfully affects adult lives. Both authors return to their experiences with indigenous peoples to show how nature is taught and wilderness understood in cultures historically grounded outside of America's cities and suburbs." "The Geography of Childhood makes clear how human growth remains rooted, as it always has, both in childhood and in wild landscapes. It is an essential book for all parents and teachers who wonder what our children may miss if they never experience local wildlife or wild landscapes."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Urban air quality is a topic which remains high on the scientific and political agenda. Concentrations of most air pollutants are higher in urban areas than in the surrounding rural regions, and given the high population densities, it is within urban areas that the majority of the population receive their air pollutant exposure. Despite the continued implementation of abatement measures, concentrations of air pollutants within urban areas frequently exceed health-based guidelines and stricter measures to restrict emissions are required. This comprehensive volume, written by authoritative authors, deals with the basic science of urban air pollution in relation to the sources and concentrations, and the atmospheric chemical and physical processes which determine those concentrations and lead to the formation of secondary pollutants by chemical reactions in the atmosphere. The health effects of urban air pollution are described as is the policy response designed to mitigate the problems. Some of the highest air pollutant exposures occur within underground railway systems and this topic is considered explicitly in its own chapter. With comprehensive coverage from sources through atmospheric processes, to human exposure and effects on health and the policy response, this topical work will be of interest to scientists and policy makers within this field as well advanced students.
