If environmentalism is a fad, it will be the last one.

For that reason the simple test of the slogan 'Consume Less' as a basis for social action on the environment would be to tell it to the blacks in the ghetto. The message will not be very well received for there are many people in this country who consume less than is needed to sustain a decent life.

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

If environmentalism is a fad, it will be the last one.

As the earth spins through space, a view from above the North Pole would encompass most of the wealth of the world - most of its food, productive machines, doctors, engineers and teachers. A view from the opposite pole would encompass most of the world's poor.

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?

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.
