Perhaps the simplest example is a synthetic plastic, which unlike natural materials, is not degraded by biological decay. It therefore persists as rubbish or is burned-in both cases causing pollution. In the same way, a substance such as DDT or lead, which plays no role in the chemistry of life and interferes with the actions of substances that do, is bound to cause ecological damage if sufficiently concentrated.

In every case, the environmental hazards were made known only by independent scientists, who were often bitterly opposed by the corporations responsible for the hazards.

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.

Despite the dazzling successes of modern technology and the unprecedented power of modern military systems, they suffer from a common and catastrophic fault. While providing us with a bountiful supply of food, with great industrial plants, with high-speed transportation, and with military weapons of unprecedented power, they threaten our very survival.

The environmental crisis is a global problem, and only global action will resolve it.

World War II had a very important impact on the development of technology, as a whole.

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