World Ozone Day on September 16

 

World Ozone Day

September 16 was designated by the United Nations General Assembly as the International Day for the Preservation of the Ozone Layer. This designation had been made on December 19, 2000, in commemoration of the date, in 1987, on which nations signed the Montreal Protocol on Substances that Deplete the Ozone Layer.

In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer.

The closure of the hole in the ozone layer was observed 30 years after the protocol was signed. Due to the nature of the gases responsible for ozone depletion their chemical effects are expected to continue for between 50 and 100 years.

What is Ozone layer?
 
The Ozone layer protects the planet from Ultraviolet (UV) rays of the sun. Ozone is made up of three atoms of oxygen. It is highly reactive gas and is represented by O3. It occurs naturally as well as a man-made product in the Earth's upper atmosphere i.e. stratosphere and lower atmosphere i.e. troposphere. The Ozone layer is present in Earth’s atmosphere (15-35km above Earth) in the lower portion of the stratosphere and has relatively high concentrations of ozone (O3). Naturally, it is formed through the interactions of solar UV radiation with molecular oxygen O2. It reduces the harmful UV radiation reaching the Earth's surface.
 
The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons). Since the early 1970's, scientists observed reduction in stratospheric ozone and it was found more prominent in Polar Regions. ODS substances have a lifetime of about 100 years.
 
World Ozone Day

Ozone is like a “MOTHER” of EARTH….who protect her child from harmful radiations. Our Mother. World Ozone Day

Doesn’t let the future go up in smoke. SAVE THE OZONE. Save ozone, Save a life (God Bless you). World Ozone Day.

Life depletes when Ozone Depletes… So to save life save Ozone.

Reduce depletion of ozone, otherwise you will be in the Redzone.

You dont have to be a mayor to help protect the ozone layer.

The only thing that stops the earth from getting fried is the ozone layer. Protect it and protect yourself. World Ozone Day

Ozone is like a “MOTHER” of EARTH….who protect her child from harmful radiations. Our Mother. World Ozone Day

Let’s take an oath to protect the ozone layer and save life on earth this World Ozone Day!

As umbrella protects us from rain, ozone protects the earth from the sun.
Go green, go genius, stamp the carbon, stand tall, and stitch the ozone layer.
