As the nation approaches a 300-million population and a trillion-dollar economy and as our strip cities, industrial complexes, and communities grow, the time remaining to prevent the destruction of our natural environment and erosion of our resources needed to support life is becoming dangerously short.
As each man-made change occurs, it has effects on the environment which we, through shortsightedness, frequently fail to anticipate. And since our physical resources are limited and interdependent, the misuse of each resource alters the availability or usefulness of the others.
The nation is rapidly coming to realize that if action is not taken now on the national, regional, and local levels to preserve our environment, we will soon lack the environment and resources necessary to sustain our civilization and perhaps human life itself.
Where will more and more people live, work, and play? It may soon be true that in many metropolitan areas the nearest open space for a picnic within 25 mi of the downtown area will be the city dump.
Where will we dispose of the waste products of our increasing population and industrialized society?
The conservation of wildlife, wilderness, and recreation land and the pollution of our water, land, and air have finally become matters of public concern.

Geologic Mapping for Environmental Purposes
The rapid increase in the development of land, the exploitation of minerals, and the related accelerated environmental impacts have caused an explosion of demand for information that can be used as a guide to land use decision-making. “Environmental Geology Mapping” was the topic of an engineering geology symposium at the 1972 annual meeting of The Geological Society of America; natural resources planning and the roles and interrelations of geology and geologists, planning and planners were discussed. This book presents the coverage of those subjects because of their continuing timeliness and the need for a reminder that we must provide data that are relevant and usable for interdisciplinary considerations in natural resources planning. The authors express their ideas on how to translate professionally the traditional, basic earth-science data into forms that are adaptable to interdisciplinary solutions of environmental problems. They unanimously state that this conversion of data has to result in a viable input for decision-making, and it must also stand the scrutiny of the real world; that is, it must receive public endorsement and support.
