International Ozone Day is an example of our global integrity and the collective efforts made through phased methods. Every year on September 16, International Ozone Day is celebrated to promote the conservation of the ozone layer. It was first initiated in 1987 under the Montreal Protocol, where all countries agreed on the damage to the ozone layer. 

Efforts were made to control and eventually eliminate the substances causing harm to the ozone layer in a phased manner. As a result, today the ozone layer is recovering. This has also had a positive impact on climate change-induced global warming. Without these efforts, the Earth's temperature would have been significantly higher than it is today.

What is the Montreal Protocol and how did it begin?

The Montreal Protocol's goal was to protect the ozone layer by scientifically and technologically controlling and eliminating all substances that were damaging it.

Scientists had already confirmed the damage to the ozone layer. A global call was made for all countries to come together to protect it. On March 22, 1985, the Vienna Convention formally addressed the issue, and 28 countries signed it.

In September 1987, nearly 100 chemicals that were harming the ozone layer were identified. A phased ban was then implemented on these chemicals, gradually eliminating them. However, some chemicals that had no alternative, such as those used in asthma treatment or in aircraft and submarines, were exempted.

Why was healing the ozone layer important?

The ozone layer is crucial for maintaining the balance between nature and life on Earth. It acts as a shield, protecting the Earth from harmful ultraviolet radiation from the Sun. It also helps maintain a stable temperature on Earth.

However, certain man-made chemicals such as Halon, Chlorofluorocarbons (CFCs), and Hydrochlorofluorocarbons (HCFCs) were causing severe damage to the ozone layer. These chemicals were commonly used in aerosols and cooling systems (like refrigerators and air conditioners).

The ozone layer is Earth's first line of defense, protecting us from the Sun's ultraviolet radiation. Without it, the risks of skin cancer, cataracts, and other health hazards increase. It could also severely harm plants, agriculture, and ecosystems.

Without the ozone layer, life on Earth would be unimaginable. Therefore, protecting the ozone layer becomes a top priority for us.
