Two months ago the news came that the Antarctic ozone layer hole Which is the largest and deepest gap in the ozone layer since 40 years now getting better according to world metrological organization and the credit goes to the worldwide lock down which lessen in the ozone depletion.

But, now scientists reported that the returns in emissions of CFC 11 and Pollution delay or redepleting  the earth’s ozone layer.

OZONE is a gas which is present naturally in earth's  atmosphere and protect us from harmful radiation. ozone layer can be depleted and broken through interaction with man-made compounds in the upper atmosphere. These man-made compounds when emitted into the atmosphere they go and react with ozone and by reacting with ozone, they reduce ozone.

OZONE Is present into two different layers in our atmosphere:-

1.Tropospheric layer-The ozone Which are present in troposphere is considered as bad ozone.

2.stratospheric layer- The land which are present in stratosphere is considered as good ozone.

the reason behind this difference is, in troposphere that is lowest level of atmosphere, ozone act as an air pollutant and stratospheric ozone good because it’s basically helping us encountering the UV rays from the sun and harmful rays does not reach the earth surface.

CAUSES OF OZONE LAYER DEPLETION:-

1.CFC- Chlorofluorocarbon

2.HCFC- Hydro chlorofluorocarbon

3.HALONS

4. Methyl bromide

5. Carbon tetra- cloride

Because of these the large hole Create in our  ozone layer and will take many years for healing.

IMPACTS OF OZONE LAYER DEPLETION:-

In the absence of ozone layer, UV rays will be able to penetrate in earth's  atmosphere and reach the earth surface very easily and cause many health problems In human body and animals or plants .

· skin cancer And effect in immune system If, human Prolonged exposure with UV B rays.

· Effect on Aquatic ecosystem- UV rays destroy the bases of the marine food chain.

·  Skin cancer in animals and UV damage is the plant growth, change flowering times, makes plant more vulnerable to disease to produce toxic substances. UV rays could even losses of biodiversity and the species.

How we protect our ozone layer:-

1. Minimize the use of cars if you really want to use a car so, try to share car with others to decrease the use of ca in order to pollute less and save.

2. Use public transport more and more like buses, train or you can use bycycle also.

3.Avoid the consumption of gases like CFC and HCFCs ,Which are dangerous to the ozone layer.

4. CFC used in refrigerator and in fire extinguisher should be replaced with eco-friendly alternatives.
