This text presents scientific evidence produced by ocean scientists on the current state of ocean ecosystems, globally. Covering over 70 per cent of the earth's surface, the ocean is the world's largest common property resource, jointly owned by over six billion humans. It is the foundation for life on earth as we know it. The content ranges from the movement of essential nutrients in the sea to the loss of diversity as a consequence of overharvesting practices and habitat loss. Essential to the maintenance of complex ecosystems is the proper functioning of biogeochemical cycles within the oceans. This book addresses this topic by detailing behaviour of the essential nutrients, nitrogen and phosphorus, and discussing how these cycles are being altered so as to compromise the function of ocean ecosystems. Issues regarding how man-made activities are further altering the structure of oceanic systems are also discussed.In addition, the mechanism for and consequences of the loss of biodiversity are described, with issues such as overfishing, the invasion of exotic species, and the loss of ocean habitat being presented in such a way that the average reader can readily grasp the concepts. Rather than end on a negative note, the final chapters provide recommendations and directions for solutions as to how to reverse these human-induced trends.

'I would certainly recommend that this book be put on the reading list for any ecological or environmental degree course.' Biological Conservation, 107 (2002) 'Waters in Peril is nevertheless a very useful, well-written and up-to-date review of the global status of our oceans and their conservation. This is a valuable addition to undergraduate or postgraduate courses on marine conservation, biodiversity and pollution. ...highly recommend this book to the libraries of universities and marine research institutes.' Hydrobiologia, 493 (2003)
