Where would we be without chlorophyll? Thanks to our Master Designer, we don’t have to find out!

After the winter covering of snow, it’s always refreshing to see the earth burst forth in colors, especially green. Green is for us not just a color of beauty but is also a color of life. Let me explain.
Symbiosis is a word describing the relationship between two living things in which each benefits the other. One important example of this is our relationship to green plants (trees, grass, Brussels sprouts, etc.). When we breath, our bodies take in oxygen from the air and use it to function in various ways. We then expel a waste product, carbon dioxide. This process is called respiration. Thus, for people and animals to function, we need a constantly renewed source of oxygen.
Green plants, on the other hand, make their own food through a process called photosynthesis. To do this, they need carbon dioxide, sunshine, and water. The waste product of this process is oxygen. This process is simple enough to write (6CO2 + 6H2O (+ light energy and chlorophyll) → C6H12O6 + 6O2), yet scientists have not been able to duplicate it in a laboratory. We remain dependent on the green stuff to stay alive.
Thus, in respiration we give off carbon dioxide which the plants need and they give off oxygen which we need. Pretty neat design, isn’t it? It takes seven average sized trees to produce enough oxygen for one person. But most (c. 90%) of the oxygen we breathe is produced by water plants. Through wind currents, oxygen is spread around the world and life continues. What a magnificent design! What an awesome Designer!
