ABSTRACT
In 1990, a book written by L.K.Caldwell Between Two Worlds: Science, the Environmental Movement and Policy Choice was published by Cambridge University Press to deal with the relationships between science and the world of people. Caldwell shows how science can help shape new relationships between people and the environment when the information is clearly transmitted-which is not always the case. He reminds us that when the popular environmental movement was looking to science for guidance, most natural sciences were unprepared to explain the interactions between population expansion, technological advance, and environmental changes in such a way that people could understand, so as to bear effectively on public behaviour and decisions. The fundamental question of environmental policies today is whether the realities of this earth, as the sciences reveal them, can be translated into representation and behaviour appropriate to the continuation of life on earth. As Schneider (1990) writes: ‘My principal purpose…is to make basic issues and policy implications of global atmospheric change more accessible to the public’, without loss of scientific validity and soundness so that the public can be concerned with the future of this planet.
