Recipient of the ECI Prize in 1993 for terrestrial ecology. Reviews and analyses the essential aspects of modern ecological research and its bearing on society and on related sciences. The author deplores that many ecologists are not doing enough to motivate society into counteracting the increasing degradation of our environment. Hence, he outlines and discusses what, in his opinion, research ecologists should do to avoid the world's plunge towards ecocatastrophe.
