Perspective 



A Growing Source of Fuels and Minerals 



Minerals and fuels arc essential to the world's industrial economy. In the 

 last 30 years the U.S. has consumed more minerals and fuels than the entire 

 world used in all previous history. Competition for low cost mineral raw 

 materials will intensify as both developed and developing nations step up 

 their industrial economies and encourage the processing of their own ores. 

 To assure that the United States has an adequate and dependable supply of 

 minerals and fuels, existing resource bases must continue to be diversified 

 and the discovery rates of new economical sources increased. 



Projected world and U.S. energy demands to the year 2000, as well as the 

 estimated quantities of offshore oil and gas required to satisfy these demands, 

 are summarized in Figure II-l 1. The United States is the heaviest consumer
