Waters in Peril (Hardcover, 2001 ed.)

Waters in Peril presents the most recent scientific evidence produced by internationally renowned ocean scientists on the current state of ocean ecosystems, globally. Covering over seventy percent 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. Waters in Peril addresses this topic by detailing behavior 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 Doomsday' note, the final chapters provide recommendations and directions for solutions as to how to reverse these human-induced trends.
