 counties by the presence of the estuarine zone. 



Such gross means can give only an order-of-magnitude estimate of 

 even the direct economic value of the estuarine zone and cannot 

 possibly reflect either indirect benefits or the social importance 

 of the estuarine zone, much less its ecological value. 



Valid criteria for evaluating the importance of the estuarine 

 environment or the value of individual estuarine uses, to a 

 community must, however, go beyond the reach of economic approxi- 

 mation and recognize the fundamental relationship between man and 

 his environment. Wherever there are people the environment will 

 be exploited to satisfy the needs and desires of man and his 

 civilization. 



Increasing environmental pressures from demographic and commercial 

 development are paralleled in the same community by the increasing 

 desire for greater recreational use. That these can be compatible 

 is clearly shown by the San Diego Bay example. Such community 

 reactions as in San Diego and in San Francisco demonstrate that, 

 while people need commercial development and use, they want a 

 safe and enjoyable environment at the same time. Effective 

 management, therefore, should direct its efforts not toward 

 excluding some uses, but toward accomodating all uses without 

 environmental damage.
