Renewability and sustainability are two critical factors that will decide the future course of the world. We have to learn from Nature how sun is able to sustain life on earth for millions of years without the slightest hitch. The sun provides light energy for the photosynthesis to generate Carbohydrate using carbon dioxide from the atmosphere and water. The green pigment in the leaves of the plant ‘Chlorophyll’ catalalyses the photosynthesis. The plant grows and serves as food for animals. After certain period both the plant and animal dies and becomes carbon. New plants and animals are produced and the cycle continues. The dead plant decays and serves as manure for the new plant. A sequence of combinations of atmosphere, photosynthesis, micronutrients in the soil, absorption of carbon dioxide from air and release of Oxygen into the atmosphere, food production, life sustainenace, death and decay play like a symphony in…
