Conservation of Vital Resources is one episode in a 1973 series, On Ecology, produced and directed by Samuel Hudson. This episode takes a look at the the use and abuse of natural resources. Lecturer Desmond Dhoodce breaks down the difference between several types of resources and explains the complicated process of dirt farming. Dhoodce then brings the viewer to a tree plantation in Silsbee, Texas, in Hardin County. Although he critiques tree farming, he acknowledges the practice as the lesser of two evils when compared to the use of herbicides and pesticides. The episode concludes with the tragic and dangerous consequences of environmental exploitation, such as the extinction of the ivory bill woodpecker. Desmond urges his audience to acknowledge the dire effects that seemingly miniscule actions may have on the environment.
