probably more than one-third, will occur in the estuarine zone. 

 Population growth will spur the expansion of urban and suburban 

 developments. Major portions of urban development will develop 

 along all major coastlines of the Untied States — particularly the 

 Atlantic Coastline north of North Carolina, Florida, the middle 

 portions of the Gulf of Mexico and California. The economy will 

 also expand both in scope and diversity to meet the demands of an 

 increasing, wealthy population. Much of this economic activity will 

 be centered on or closely adjacent to the Nation's estuaries and 

 coastal shoreline. These economic activities will vary from place 

 to place due to the location of natural resources and the demands 

 for these resources, historic circumstance, availability of markets 

 and changes in technology. 



The general growth of both the population and economy is reflected 

 in expanding trends noted for more specific activities related to 

 the estuarine environment: marine fisheries, civilian and national 

 defense transportation, marine mining and processing, outdoor 

 recreation and waste discharge. All of these activities, as well 

 as the associated secondary and marginal activities located in the 

 estuarine zone, will intensify in future years. Marine fisheries 

 and outdoor recreation are highly dependent upon naturally 

 occurring properties of estuarine ecological systems. Transporta- 

 tion, mining and waste discharge are much less tied to these
