APPLIED ECOLOGY 361 



society. It is hoped that, in this last chapter, enough practical 

 aspects of ecology have been suggested to show its wide appli- 

 cability. Furthermore, the aim has been to show that its application 

 is necessary if man is to continue to enjoy the full benefits of his 

 environment upon which he is dependent, in which he is a factor, 

 and over which he is a dominant. We have suggested that people 

 with a wide variety of interests have concerned themselves with 

 the general subject of human ecology. Among plant ecologists, 

 Dr. Paul B. Sears is outstanding for his efforts in behalf of applied 

 ecology and; particularly, human ecology. As a conclusion to this 

 section it is, therefore, entirely proper that we quote one of his 

 chapter headings from "Life and Environment" 220 which reads, 

 "The social function of ecology is to provide a scientific basis 

 whereby man may shape the environment and his relations to it, 

 as he expresses himself in and through his culture patterns!'
