World Ozone Day

World Ozone Day is an annual holiday dedicated to the protection of the Earth’s ozone layer. Celebrated on September 16th. Officially approved by the UN General Assembly in 1994.


The ozone layer is a thin layer of gas. Without it, as well as without the atmosphere, life on the planet is impossible. The protective gaseous layer allows absorbing excess solar radiation, thereby maintaining the optimum temperature regime of the Earth, at which life is possible.

During the stage of active industrialization, absolutely no attention was paid to ecology, because the main goal was to develop industry. Research began only in the second half of the 20th century. In the 70s, it was found that the ozone layer had become much thinner. The so-called ozone holes were formed, which were fixed at the south and north poles. The reason was the production gases emitted into the atmosphere, especially various refrigerants that were used in refrigerators and industrial cooling systems.

In 1985, a convention was signed, according to which 28 countries should participate in the search for a solution to the problem of the ozone layer. Three years later, a list of hazardous industrial substances was presented. The rejection of them made it possible to prevent destructive processes in the future.

Interesting facts

  • The thickness of the protective layer is 0,3 cm.
  • Ozone has a scent that we associate with freshness. You can hear it after a thunderstorm.
  • If the ozone layer suddenly disappeared, then humanity would die out from massive oncology diseases provoked by excessive solar radio emission.

How to celebrate

Celebrating World Ozone Day is a great opportunity to learn more interesting information about the planet’s ozone layer. Attend lectures on the relevant topic, which are often held at universities. You can also help environmental organizations by donating some money to them.

Create a social media post about this holiday. Emphasize the importance of preserving the ecology of our planet, because the Earth is a common home for all people.
