In developing these needs, the committee has assumed that our soil resources should be used to maintain a sustained high standard of living for the people in the United States as well as those in developing countries. However, in assuming this responsibility, the committee has also been concerned with urban, recreational, and other land uses that will meet the needs of the people without polluting our soil and water resources.
