This book is about applied science. The structure of each chapter is
designed around a set of environmental problems. So, this book is not
pure science with applications tacked on at the end: the applied problems
are at the heart of it. Nevertheless, fundamental science is crucial to
tackling these problems. Why this must be so can be illustrated by Table
10.1 (p. 284), which shows how many thousand species are known in
some major groups of animal and plant.
