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.

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

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.

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

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.

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

Recycling is a good thing to do. It makes people feel good to do it. The thing I want to emphasize is the vast difference between recycling for the purpose of feeling good and recycling for the purpose of solving the trash problem.
