In December 2000, The United Nations General Assembly declared September 16 as the Ozone Day. This day marked for the prevention of the ozone layer. Ozone day is celebrated on September 16 every year to prevent the ozone layer. The day designated in recognition of the date, in 1987 where nations signed the Montreal Protocol on substances that Deplete the Ozone layer. According to the UN General Assembly, the hole in the ozone layer was observed 30 years after the protocol was signed. The theme for this year is 32 years and Healing.

International Ozone Day 2019: Know The Importance
Ozone is helpful and harmful both for living beings on the planet. Near the ground, It acts as a harmful air-pollutants which can cause serious diseases like Asthama attacks and Heart diseases. But above the surface of the earth, it behaves as a shield of the earth. It protects the planet from many UV rays and harmful radiation from the Sun. The ozone layer is present in the stratosphere with 90% of the ozone in it.
Ozone protects the planet from the most harmful Ultra-violet light, UV-B and UV-C. these rays are very harmful for living beings. As a supporting agent, Oxygen also absorbs some wavelengths of it. together they make a perfect combination that protects the earth by absorbing 95 to 99.9% of Harmful rays. The stratosphere level of the earth is very heated by the ozone and oxygen that absorb rays and generate heat in return. That is why the layer is getting warmer day by day.
The Ozone hole is not a hole in reality as it is the thinning of the Ozone layer in the Stratospheric layer above the earth. British scientists at Halley Bay, Antartica discover that there is a major drop in the Ozone levels by 10%. At sometimes, the hole becomes larger day by day and the ozone level is also decreasing season by season.
UN Secretary-General Antonio Guterres on the occasion of World Ozone Day said- “As we rightly focus our energies on tackling climate change, we must be careful not to neglect the ozone layer and stay alert to the threat posed by the illegal use of ozone-depleting gases. The recent detection of emissions of one such gas, CFC-11, reminds us that we need continued monitoring and reporting systems, and improved regulations and enforcement. ”
On this occasion, the UN said to the citizens of the world that support the Kigali Amendment. It means, by letting the level of hydrofluorocarbons (HFCs), the world can avoid a major change of temperature by the end of the century. HCFs are harmful climate-warming gases. To protect the Ozone layer, show support to Kigali Amendment that came into force on January 1.
