Abstract :
The United States is finally facing up to the fact that we can no longer tolerate the uncontrolled application of technology. We are now seeing the results of what has seemed almost a national program of conspicuous consumption — depletion of our natural resources and the deterioration of our environment. Hopefully, the trend can still be reversed by planning and control. Over the years, a substantial body of literature has accrued on this vital topic, and an attempt is made here to provide the interested student with a guide.
