ABSTRACT
Our generation enjoys the fruits of technological achievements that have increased energy and resource availability far beyond subsistence. But at the same time we are confronted with exploding populations, dwindling natural landscapes, and mounting pollution, which threaten to cancel many of the advantages of this energy-rich society. The realization that man is an integral part of his surroundings has directed our attention,’ more and more, to understanding and protecting our endangered environment and to reordering technology to achieve new goals. Thus, interest in ecology and application of ecological principles to human affairs has become a new intellectual frontier. Environmental awareness, worldwide in scope, reflects that, for the first time in its history, humanity faces ultimate rather than merely local limits to human needs and aspirations.
