Oceans Under Threat (Considering Conservation Series)

Oil spillage, poisoned fish, radioactive dumping - although the oceans cover almost three quarters of our planet, serious damage seems to have been done to this precious natural resource. Philip Neal begins with the basics - the tides and currents that control life in the seas, and the plankton which are the foundation of oceanic life. He then examines the chief ways in which mankind threatens marine life - through over-fishing, pollution, dumping and mining of the seabed. The book concludes with a discussion of the political problems facing ocean conservationists, and suggestions for readers to follow up themselves.
