The environmental crisis is a signal of this approaching catastrophe.

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.

The modern technologist is less 'sorcerer' and more 'sorcerer's apprentice'.

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.

Environmental pollution is an incurable disease. It can only be prevented.

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.

Seen that way, the wholesale transformation of production technologies that is mandated by pollution prevention creates a new surge of economic development.
