for economic expediency and look to the 

 ocean as a sink. When we look to the 

 ocean, we look first to the coastal 

 zone. 



When an ecologist or an oceanog- 

 rapher thinks of the ocean, he thinks 

 of very deep water, usually far from 

 land. However, most ocean dumping is 

 virtually done on the beach. The real 

 cost of dumping in the deep ocean is 

 high, perhaps prohibitive in some in- 

 stances, so we still have the problem of 

 eutrophicating the coastal zone. When 

 this kind of question comes up, one 

 needs to ask where in the ocean is one 

 going to dump waste. The coastal zone 

 is much more resilient than the estuary, 

 if one considers the coastal zone all 

 the way out to the edge of the shelf. 

 It is a large area, and it can take a 

 lot of abuse. Therefore, we have to 

 look at both sides of these questions. 

 There are going to be many impacts on 

 the coastal zone, taken in a broad 

 sense, that are going to be quite rea- 

 sonable and which the zone can assimi- 

 late successfully. There are others 

 that it can not. Nutrients are simply 

 one of many aspects we need to consider 

 in evaluating the increasing impacts on 

 the coastal zone.
