TREE OF LIFE

A USDA film. "Portrayal of how the forestry resources of the United States have been depleted to the extent that regulated cutting is now necessary on both public and private timber land. Animated graphs comparing early population and forest stands to those of the present. Illustrations of how unregulated and complete stripping of forest land leaves ghost towns and floods in its wake. Methods of conservation: National forests provide permanent supply by means of selected cutting. Fire protection by means of lookout towers. Indications of the need for selected cutting on private lands." California.
