Book Description
• • • John Harper • • • Nature conservation has changed from an idealistic philosophy to a serious technology. Ecology, the science that underpins the technol ogy of conservation, is still too immature to provide all the wisdom that it must. It is arguable that the desire to conserve nature will in itself force the discipline of ecology to identify fundamental prob lems in its scientific goals and methods. In return, ecologists may be able to offer some insights that make conservation more practicable (Harper 1987). The idea that nature (species or communities) is worth preserv ing rests on several fundamental arguments, particularly the argu ment of nostalgia and the argument of human benefit and need. Nostalgia, of course, is a powerful emotion. With some notable ex ceptions, there is usually a feeling of dismay at a change in the sta tus quo, whether it be the loss of a place in the country for walking or rambling, the loss of a painting or architectural monument, or that one will never again have the chance to see a particular species of bird or plant.

Book Description
To assist the Congress and the administration in deciding the future course of the national waer-quality program, we reviewed the findings of recent studies on the quality of waer in U.S. rivers and streams and the progress that has been made toward the goals of the Clean Water Act. From our in-depth review and synthesis of the literature and the advice of expert consultants, we formulated four evaluation questions: 1. What is the present condition of the nation's water quality? 2. How has the nation's water quality changed over time? 3. What pollution sources degrade water quality? 4. What has been the effect of the Construction Grants Program on water quality? In addition to reviewing and synthesizing relevant inforrmation from the studies that addressed these questions, we evaluated the methodologies they employed to reach their conclusions."--Page 12.
