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

What is needed now is a transformation of the major systems of production more profound than even the sweeping post-World War II changes in production technology.

We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation.

In general, any productive activity which introduces substances foreign to the natural environment runs a considerable risk of polluting it.

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

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.

Environmental quality was drastically improved while economic activity grew by the simple expedient of removing lead from gasoline - which prevented it from entering the environment.
