For courses in Environmental Geology taken by introductory, non-science majors. Also appropriate for Physical Geology courses emphasizing an environmental perspective. As the human population increases, many decisions concerning our use of natural resources will determine our standard of living and the quality of our environment. This text helps non-science majors develop an understanding of how geology and humanity interface. Ed Keller--the author who first defined the environmental geology course--focuses on five fundamental concepts of environmental geology: Human Population Growth, Sustainability, Earth as a System, Hazardous Earth Processes, and Scientific Knowledge and Values. These concepts are introduced at the outset of the text, integrated throughout, and revisited at the end of each chapter. Included with every text, the Hazard City CD-ROM gives instructors meaningful, easy-to-assign, and easy-to-grade assignments based on the idealized town of Hazard City.
