Part Four 

 WHAT REMAINS? 



Too long we have reckoned our resources in terms of 

 illusion. Money, even gold, is but a metrical device. It 

 is not the substance of wealth. Our capital is the accumu- 

 lation of material and energy with which we can work. 

 Soil, water, minerals, vegetation, and animal life — these are 

 the basis of our existence and the measure of our future. 



Paul B. Sears, This Is Our World, 1937.
