The ozone layer, the original shield of Earth which protect us from UV rays produced by the sun. If you don't have any knowledge about ozone then I will give a quick recap.

  ozone is trioxygen molecule which appeared in a pale blue colour. When oxygen molecules reach stratosphere (where ozone layer exist) then oxygen molecule get a breakdown and it attaches to a newly entered oxygen molecule and it forms ozone. This collection of the ozone layer does not allow harmful rays to enter our Earth. Have you ever think what if the ozone layer gets disappear? Let's know about all of this in a simple way.

Immediate after disappearing ozone layer.


If the ozone layer disappeared then harmful UV rays will enter our Earth. They will interact with our DNA by entering a skin cause cancer and many more types of problems.
UV rays interact plants photosynthesis process if photosynthesis process will stop then the whole food chain will stop which results lost of plants from Earth.

UV rays can destroy the eye of the whole human being as well as animals these rays are very dangerous for the eye. And also destroy the immune system.

Rising in earth temperature which kills many species as well as plant.which also leads melting of ice in Antarctica as well as our Himalaya which leads to an increase in the level of water.

The gases which are present in the earth will move to space. Earth lost the whole collection of gases which produce an imbalance in nature.

Because of the rising in temperature, water evaporates, and water level decrease.

Conclusion

If the ozone layer disappears then whole living animals and plants get destroyed. Earth becomes a living hell and no one can read this page(😂 I know this one is a bad joke).
   This is just thinking but what if we cut tree daily, what if we make pollution, what if we destroy nature for our comfort. Disappearing ozone is just thinking but if we repeatedly doing those things then we will definitely kill our future. So please #save_nature.
