This film could be a magic door to young people. They will be 

 hard to convince that such marvels of life exist in the ocean. The 

 film is an excellent portrayal of the ocean as an ecological area, 

 the myriad of animals, their problems in survival. Most of all it is 

 excellent as an introduction to the exciting kinds of adventure 

 which research in the ocean makes possible. Except for a few words 

 which may need explaining, the best age to show this film the first 

 time is at the junior high school level when imagination is so easily 

 fired. It definitely bears repetition in courses of biology, ecology, 

 oceanography, etc. This is an exceptionally beautiful film. 



POPULATION ECOLOGY

What causes a population of fruit flies, mice, rabbits, or any living 

 animal to increase, level off, then decline? This is well presented 

 with a graph superimposed on the film to clarify the idea and to 

 add drama. The human population curve is seen to be markedly 

 different today from what it was in primitive times when it was 

 similar to that of other animals. This change, following the agri- 

 cultural revolution in the history of mankind, is due to man's con- 

 trol over his environment. What man has done, what the effects of 

 overpopulation are, and what man can do about the future is the 

 overall theme. This film is very stimulating and should result in 

 considerable social studies reading research as well as lead to some 

 excellent biology investigations.

The important facts about water are here spelled out; literally, 

 at the beginning, in many languages then figuratively. This is a 

 very artistic approach to the problem of water in all our lives.
