For the inhabitants of many of the world's major towns and cities,
estuaries provide their first and nearest glimpse of a natural
habitat. Despite the attempts of man to pollute or reclaim it, the
estuarine ecosystem continues to provide a fascinating insight into
a natural world where energy is transformed from sunlight into
plant material, and then through the steps of a food chain is
converted into a rich food supply for birds and fish.
When the previous editions of this book appeared, biologists were
beginning to realize that the estuarine ecosystem was an ideal
habitat in which to observe the processes controlling biological
productivity. In the intervening period, many more estuaries and
their inhabitants have been studied intensively. It is now possible
to answer many of the questions posed by the earlier editions, and
to pursue further the explanation of high productivity in estuaries
and of energy utilization at different trophic levels within
estuarine food webs. A significant amount of new information has
also been accumulated on the human use and abuse of these habitats,
particularly the effects of pollution. Although the world's seas
are vast and may appear capable of receiving unlimited quantities
of human effluent, such waste is often first discharged into the
confined waters of estuaries. In practice, marine pollution is
often essentially estuarine pollution. To reflect the huge impact
of humans on estuaries, and to consider how we may either modify,
remove or enrich the estuarine ecosystem, three completely new
chapters have been prepared in this edition. These consider
anthropogenic change (including pollution) in estuaries, the
diverse uses and abuses of the estuarine habitat by man, and the
methods used to study human induced changes in estuaries. Finally,
this text examines the ways in which estuarine management can
monitor, control or prevent the pollution and destruction of this
fragile ecosystem.
