UNION OIL H) COMPANY THE TOUGHEST UUBRiCAHTS /H THE FtELO T his Land of Ours , . . • \*t % \ \ Green Plants By JESSE GREEN ALL OUR FOOD originates with green plants. In addition, all our fuels—coal, oil and gas—are the products of living plants. Our industrial development was made possible by means of these fuels. A leaf is such an apparently simple thing to bear the burden of feeding all life on the earth. In its simplicity, there is great com plexity. A hundred years ago, its full importance was not known. We learned slowly that light en ergy from the sun plays on green chlorophyl of leaves to cause car bon dioxide from the air to com bine with water in the plant to form the carbohydrates, the sugars and starch, the beginning materials of all the foods for men and animals. There are many theories ex plaining the steps of photosyn thesis, as it is called in the books. There is still considerable uncer tainty among those who know the most about this marvelous proc ess. The best minds have applied their skill in an effort to dupli cate natural process, but without success. If we could only synthe size sugars from carbon dioxide and water, if we knew how to capture the sun's rays, or to use the energy of our whirring dyna mos to make food, it would be a great step in our progress. Population increases would not be much of a problem if we did not have to depend entirely upon the products of our fields with their short seasons, droughts, in sects and plant diseases. As of the present we must be content and thankful for the green plants with all the hazards that beset them. Even though we do not under stand the complete process of photosynthesis, we know that it can be used to a much greater ad vantage than is now being done. We are aware of the very poor use made of the sun's energy. Perhaps only 1 per cent of the total energy falling on an acre goes into the production of use ful crops. This is our opportunity. As it has always been, the task is to improve on Nature, to better use the materials and forces which it furnishes for us. We need to study harder, to search for the fundamental principles by which our food is now produced. This is our challenge, our frontier of today.
