"\"Treeless, level, and semi-arid.\" Walter Prescott Webb?s famous description of the Great Plains is really only part of their story. From their creation at the end of the Ice Age to the ongoing problems of depopulation, soil erosion, polluted streams, and depleted groundwater aquifers, human interaction with the prairies has often been controversial. The Grasslands of the United States: An Environmental History explores the historical and ecological dimensions of human interaction with North America?s grasslands. Examining issues as diverse as whether the arrival of the Paleo-Indians led to the extinction of the mammoth and the consequences of industrialization and genetically modified crops, this invaluable reference synthesizes literature from a wide range of authoritative sources to provide a fascinating guide to the environment of this biome."@en . .
