My entry into the environmental arena was through the issue that so dramatically - and destructively - demonstrates the link between science and social action: nuclear weapons.

What is new is that environmentalism intensely illuminates the need to confront the corporate domain at its most powerful and guarded point - the exclusive right to govern the systems of production.

It reflects a prevailing myth that production technology is no more amenable to human judgment or social interests than the laws of thermodynamics, atomic structure or biological inheritance.

The environmental crisis is a sign that the ecosphere is now so heavily strained that its continued stability is threatened. It is a warning that we must discover the source of this suicidal drive and master it before it destroys the environment-and ourselves.

Air pollution is not merely a nuisance and a threat to health. It is a reminder that our most celebrated technological achievements-the automobile, the jet plane, the power plant, industry in general, and indeed the modern city itself-are, in the environment, failures.

Technologists practice faith too; 'Faith that problems have solutions before having the knowledge to solve them.'
