Informationen zum Autor Dr Sarah Woodin, PhD, is a lecturer in the Department of Plant and Soil Science, University of Aberdeen. Dr Mick Marquiss is a Population Ecologist with the Institute of Terrestrial Ecology at Banchory Research Station. Klappentext The book ends with four chapters concentrating on man's impacts on the Arctic environment. Zusammenfassung Once thought of as a pristine environment it is now all too apparent that the Arctic is a sink for pollutants transported northwards over long distances in the atmosphere and oceans and is also likely to be subject to major climate change as a result of global warming.
