Nature sustains the environment of earth in such a way that every entity in it behaves in a systemic way such that existence of life on this planet is ensured. However, the anthropogenic activities are disconcerting this natural balance of the atmosphere. One of the consequences is the depletion and formation of ozone in stratosphere and in troposphere respectively. The outcomes associated with the existence of ozone in different regions of the atmosphere should be known to a common person. An attempt has been made to present this important issue in a short and simple way to create awareness about the effects of ozone among the readers. Some diagrammatic presentations of concerned chemical reactions have been projected to develop the clear understanding of the chemistry underlying in these reactions.
