Essential Environmental Science provides a non-quantitative approach that is based on principles, critical thinking and the big questions that are driving the field today. It offers a condensed look at the field, covering topics in way that will help readers answer the "big questions." It eliminates more detailed or advanced topics to make the material more accessible while also placing the focus on today's important issues.
Edward A. Keller was chair of the Environmental Studies and Hydrologic Sciences Programs from 1993 to 1997 and is Professor of Earth Science at the University of California, Santa Barbara, where he teaches earth surface processes, environmental geology, environmental science, river processes, and engineering geology,. Prior to joining the faculty at Santa Barbara, he taught geomorphology, environmental studies, and earth science at the University of North Carolina, Charlotte. He was the 1982-1983 Hartley Visiting Professor at the University of Southampton, a Visiting Fellow in 2000 at Emmanuel College of Cambridge University, England, and Recipient of the Easterbrook Distinguished Scientist award from the Geological Society of America in 2004. Professor Keller has focused his research efforts into three areas: studies of Quaternary stratigraphy and tectonics as they relate to earthquakes, active folding, and mountain building process; hydrologic process and wildfire in the chaparral environment of Southern California; and physical habitat requirements for the endangered Southern California steelhead trout. He is the recipient of various water Resources Research Center grants to study fluvial processes and U.S. Geological Survey and Southern California Earthquake center grants to study earthquake hazards.
Professor Keller has published numerous papers and is the author of the textbooks Environmental Geology, Introduction to Environmental Geology and (with Nicholas Pinter) Active Tectonics (Prentice-Hall). He holds bachelor's degrees in both geology and mathematics from California State University, Fresno; an M.S. in geology from the University of California; and a Ph.D. in geology from Purdue University.
Daniel B. Botkin is President of The Center for the Study of Environment, and Professor Emertius of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, where he has been on the faculty since 1978, serving as chairman of the Environmental Studies Program from 1978 to 1985. For more than three decades, Professor Botkin has been active in the application of ecological science to environmental management. Trained in physics and biology, Professor Botkin is a leader in the application of advanced technology to the study of the environment. He was one of the pioneers in doing research on possible ecological effects of global warming, starting this work in the late 1960s, and continuing to the present.
The originator of widely used forest gap-models, he has conducted research on endangered species, characteristics of natural wilderness areas. His recent research includes studies of the bowhead whales, an endangered species hunted actively by Yankee whalers in the 19th century, important since ancient times to the Eskimos, and one of the longest-lived species, with individuals known to live 120 years.
During his career, Professor botkin has advised the World Bank about tropical forests, biological diversity, and sustainability; the Rockefeller Foundation about global environmental issues; the government of Taiwan about approaches to solving environmental problems; and the state of California on the environmental effects of water diversion on Mono Lake. He served s the primary advisor to the National Geographic Society for its centennial edition map on "the Endangered Earth. "He directed a study for the states of Oregon and California concerning salmon and their forested habitats. He has published many articles and books about environmental issues. His books include: Beyond the Stoney Mountains: Nature in the American West from Lewis and Clark to Today (Oxford University Press), Strange Encounters: Adventures of a renegade Naturalist (Penguin/Tarcher), The Blue Planet (Wiley), Our Natural History: The Lessons of Lewis and Clark (Oxford University Press),Discordant Harmonies: A New Ecology for the 21st Century (Oxford University Press), and Forest Dynamics: An Ecological Mod
