R. Montgomery (wer ist das, ich kenn nur den von dem Simpsons)
"As a geologist, David Montgomery takes the long view to the events that have shaped our world. In his book ‘Dirt’, Montgomery doesn’t hold back in his description of the global consequences of intensive, plow based tillage which continually removes soil cover and organic matter in an effort to meet the human need for an adequate diet. Continual erosion of the productive topsoil around ancient civilizations, in an effort to maximize yield, has been a root cause of the collapse and relocation of civilizations right up to the last expansion of Europeans into North America. Montgomery recognizes that we have new tools and technologies, including direct seed cropping systems, that will slow the processes in action but significantly more action is required if the trend is to be reversed.
BIO: Macarthur Fellow David R. Montgomery studies geomorphology, the evolution of landscapes. He graduated from Stanford University in 1984 with a B.S. in geology and from U.C. Berkeley in 1991 with a Ph.D. in geomorphology. He is a professor in the Department of Earth & Space Sciences at the University of Washington. His research interests range from the co-evolution of the Pacific salmon and the topography of the Pacific Northwest to the environmental history of Puget Sound rivers, interactions among climate, tectonics, and erosion in shaping mountain ranges, and giant glacial floods in eastern Tibet. He is the author of Dirt: The Erosion of Civilizations and King of Fish: The Thousand-Year Run of Salmon."
