Science in general and chemistry in particular have promoted 

 conservation in many areas, and this film, produced by American 

 Cyanamid, suggests future contributions which the chemical indus- 

 try may make as well as outlining its past accomplishments. 



Fertilizers, insecticides, use of low-grade ores and wood by- 

 products, drugs for the preservation of human resources, plastics 

 and other substitutes are included. Although slightly optimistic as 

 to the industry's productivity, the film makes clear the need for 

 conservation and some of the ways in which man can attack con- 

 servation problems. The production is excellent technically. 



AUDIENCE: Junior high; senior high; adult

Beginning by cataloging the riches of the earth's crust, this film 

 focuses its attention upon bauxite, which may be processed into 

 aluminum powder which in turn is processed, via the use of elec- 

 tricity, into aluminum. 



Mining scenes in British Guiana cover the use of hydraulic power 

 in drilling. Ships then transport the ore to eastern Canada where 

 the unfinished product is converted into aluminum powder 

 (alumina) by use of the electric power developed in the Saguenay 

 Basin. Rolling mills in Great Britain complete the process for the 

 market. The film includes one sequence on the importance of 

 aluminum to a single British Island, Jamaica, and ends with the 

 building of huge power plants in British Columbia, which will double 

 the production of aluminum. 



The part Canada plays in the manufacture of aluminum provides 

 a particularly clear picture of man's ingenuity in wresting a com- 

 mercial product from the earth. Especially significant is the part 

 this industry plays in our present day economy.
