There is much sound conservation education in this film provided 

 the teacher gives it careful initial direction. The film should be 

 preceded with a lesson on the terms "succession" and "balance of 

 nature". To guide the pupils three questions can be given to them: 

 (1) What is the condition of our planet, Earth, today? (2) How 

 did it get this way? (3) What can we do now? 



The substance of this excellent film is an answer to these three 

 questions and forms a good introduction or summary to the state 

 of our land, and how man's indifference and ignorance led to existing 

 conditions. Emphasis on knowledge and everyone's responsibility 

 for improving our legacy makes this an important film.
