If, on the other hand, the North Slope forest is not rehabilitated during the coming 

 years, the long-run outlook will presumably be quite different. Total annual costs, after 

 the first rotation, will be lower if no efforts are made to manage the timber. However, the 

 timber revenues produced by an unmanaged forest will not begin to cover even the basic 

 administration costs (fig. 18). 



Other uses, particularly recreation, are beginning to produce revenue. These uses could 

 greatly change the financial situation on the North Slope. Nevertheless, if the forest is 

 managed for its timber, revenues from that timber would go far toward paying for the ad- 

 ministration of this area. 



Relation to national development 



The wedding of the computer with increasingly sophisticated production machinery 

 has been increasing man-hour productivity at the rate of 30 percent per decade. This mount- 

 ing productivity has become a menace as well as a boon because undirected it can solidify 

 and already has to a degree solidified the depressed segments of our society by increasing 

 unemployment. Public programs to aid depressed people and depressed areas, and pro- 

 grams to beautify cities, rehabilitate slums, and remove billboards from highway rights-of-
