The age of innocent faith in science and technology may be over.

By adopting the control strategy, the nation's environmental program has created a built-in antagonism between environmental quality and economic growth.

The methods that EPA introduced after 1970 to reduce air-pollutant emissions worked for a while, but over time have become progressively less effective.

If you ask what you are going to do about global warming, the only rational answer is to change the way in which we do transportation, energy production, agriculture and a good deal of manufacturing. The problem originates in human activity in the form of the production of goods.

Everything is connected to everything else. Everything must go somewhere. Nature knows best. There is no such thing as a free lunch.

Perhaps one of the most meaningful ways to sense the impact of the environmental crisis is to confront the question which is always asked about Lake Erie: how can we restore it? I believe the only valid answer is that no one knows. For it should be clear that even if overnight all of the pollutants now pouring into Lake Erie were stopped, there would still remain the problem of the accumulated mass of pollutants in the lake bottom.

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.
