Opis

This series of A-level social biology topic books responds to the changing demands of social biology syllabuses, with each text dealing with a particular area of interest. Although the series is primarily intended for students of A-level social biology, the books will appeal to students studying a wide range of biological subjects at A-level. Environmental Concerns covers topics common to several A-level human and social biology syllabuses. It is particularly relevant to the human ecology and conservation options. The text focuses on the social and economic implications of current ecological issues as well as the basic biological concepts involved. It deals with the causes, effects and prevention of atmospheric and water pollution as well as with the disruption of ecosystems by changes in land use. The conflict of interests between conservation and exploitation is discussed, along with management techniques including the controversial method of culling to maintain diversity. The moral and aesthetic aspects of conservation and management are emphasised throughout, in addition to the scientific background of these techniques.
