The most meaningful engine of change, powerful enough to confront corporate power, may be not so much environmental quality, as the economic development and growth associated with the effort to improve it.

Finally, since human beings are uniquely capable of producing materials not found in nature, environmental degradation may be due to the resultant intrusion into an ecosystem of a substance wholly foreign to it.

In nature, no organic substance is synthesized unless there is provision for its degradation; recycling is enforced.

Our assaults on the ecosystem are so powerful, so numerous, so finely interconnected, that although the damage they do is clear, it is very difficult to discover how it was done. By which weapon? In whose hand? Are we driving the ecosphere to destruction simply by our growing numbers? By our greedy accumulation of wealth? Or are the machines which we have built to gain this wealth-the magnificent technology that now feeds us out of neat packages, that clothes us in man-made fibers, that surrounds us with new chemical creations-at fault?

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.

Because the global ecosystem is a connected whole, in which nothing can be gained or lost and which is not subject to over-all improvement, anything extracted from it by human effort must be replaced. Payment of this price cannot be avoided; it can only be delayed. The present environmental crisis is a warning that we have delayed nearly too long.
