Available in PDF, EPUB and Kindle. Book excerpt: Agriculture in the United States is in the midst of a major transition motivated by economic and environmental factors. These include water quality and quantity, soil erosion, and the compatibility of agricultural production practices and the quality of the environment. Within the context of this change, US agricultural policy seeks to balance several objectives including an abundance of food and fibre at reasonable prices, economic security for agricultural producers, and conservation of natural resources. Agricultural chemical use and soil and water quality degradation associated with agricultural production are significant among the environmental problems confronting the United States. In fact, these are now perceived as environmental problems comparable to other environmental problems such as air quality deterioration and the release of toxic pollutants from industrial sources. While the growth of agricultural chemical use is an integral part of the technological revolution in agriculture that has generated major changes in production techniques, uncertainties about the health effects of agricultural chemicals are very important concerns. Severe soil degradation from erosion, compaction, or salinisation can destroy the productive capacity of the soil. It can also impair water quality from sediment and agricultural chemicals. This important new book looks at both of these significant issues - the relationship between agricultural chemical use and the environment and the relationship between soil and water quality degradation associated with agricultural production and the environment.

Available in PDF, EPUB and Kindle. Book excerpt: Changing the Global Environment: Perspectives on Human Involvement focuses on the extent of global environmental changes and the extent to which technology can be employed to improve the global environment. This book is divided into three sections. Section I sets forth a broad perspective on specific conceptual issues of concern such as the sustainable use of the global ocean; deforestation and extinction of species; large-scale alteration of biological productivity due to transported pollutants; and soil degradation and conversion of tropical rainforests. The second section discusses technologies of remote sensing, computer-based data systems, and advanced chemical analytical techniques. The interactions among social, environmental, and economic goals and the role that technological advances might play in attaining these goals are deliberated in Section III. This publication is valuable to environmentalists and students interested in how technologies can change man's perception of the environment.
