Now in its second edition. This text has been extensively revised and rewritten to reflect the growth in environmental research during the last decade. Human-induced environmental change is occurring at such a rapid rate that, inevitably, the fundamental processes involved in biogeochemical cycling are being altered. Global Environmental Change considers alterations to the biogeochemical cycles of carbon, nitrogen, sulphur and other elements as a result of industrial/technological development and agriculture, which have significantly altered the natural environment. The book adopts a temporal and spatial approach to environmental change, beginning with the natural environmental change of the Quaternery period and continuing with the culturally-induced change since the inception of agriculture 10,000 years ago.
