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.
