THE AQUARIUM: AN ALTERNATIVE APPROACH TO ECOLOGY
A closed system like this lends itself particularly to the understanding of ecology,
providing an excellent introduction to a branch of science which emerged in the
19th century but has acquired a high profile only in the last twenty or so years.
It is not concerned simply with Man and his world, as many believe, but covers all
the mechanisms regulating relationships between living creatures and their environments,
so that all can live in harmony.
