In the speech the main point is made that the human ecosystem of the world is subject to scientific inquiry and as a consequence a new way is needed to view the planet earth. Three sets of facts have now been established concerning the earth and its inhabitants: 1) the earth and its life forms constitute a system; 2) the many sub-systems of life --molecules, cells, organisms, species, and societies-- are a part of a highly complex and interdependent ecosystem; 3) human society is an integral part of that ecosystem. The ecosystem, which behaves "intelligently", grows, adjusts, recuperates, etc., in order to remain viable. The question thus to be answered is, how can human society contribute rather than detract from that viability? The answer is given in the advice that education can play a very important role in reorienting man's thinking so that he sees himself as part of the ecosystem rather than being against it. Such a reorientation is felt to be not only necessary for the preservation of the ecosystem, hence human life, but it opens new vistas for the development of mankind. (CWB)
