Summary
Dr. Sumner explains how land surface is considered the most precious of all natural resources since it and climate together produce soil and determine the nature of vegetation. As an example of uncultivated plants which are a rich natural resource, Dr. Sumner cites our nation’s timber supplies. He points out that recent progress in reforestation has not equalized our consumption and growth of timber.
