What’s Ozone Layer?
Ozone layer is a layer of ozone molecules (O3), which is found particularly in the stratosphere layer of atmosphere ranging between 20km to 40 km from earth surface.
How it Forms?
Ozone layer is formed in the atmosphere when the ultraviolet rays from the sun break a single oxygen atom. The oxygen atom (O-) then merges with oxygen (O2) and thus forms the ozone molecule (O3).
What is meant by “Ozone Hole”?
The scientists have detected a severe drop in ozone concentration in the atmosphere, creating an enormous “hole” in the ozone layer.
Why it concerns you?
The ozone molecules absorb the sun’s ultra violet radiation (UV) which will be harmful to us if it reaches the earth surface. The most significant effects will be the increased incidence of skin cancer, eye cataracts and damage to the ecology of the earth. Most scientists agree that without the ozone layer, life on Earth will cease to exist.
What causes this phenomenon?
The ozone depletion in the atmosphere is caused by ozone depleting chemicals such as hydrochlorofluorocarbons (HCFCs) which is used in AC, Fridges and fire extinguishers.
How to protect Ozone layer?
-Buy AC and Fridge that do not use HCFCs as refrigerant.
-Buy fire extinguishers aerosol products that do not use Halons/HCFC/CFC as propellants.
-Conduct regular inspection and maintenance of AC and Fridges to prevent and minimize refrigerant leakage
-When AC needs servicing, make sure that the refrigerants are properly recovered and recycled instead of being vented to the atmosphere.
-Plating more trees and use of eco-friendly vehicles
World Ozone Day is celebrated on 16th of September every year to spread awareness and bring attention to the depletion of the ozone layer.
Ozone depletion is the major cause health hazard, climate change and global warming and disturbing the ecosystem in our mother earth. World Ozone Day provides a great platform among the people of the world to make them aware that it’s high time and we must all put our best of efforts to preserve the ozone layer.

Today 15th August 2018, India is celebrating its 72nd Independence Day to pay tribute and remember all the freedom fighters who had contributed a lot and fought for the Independence of India.
