International Day for the Preservation of the Ozone Layer

International Day for the Preservation of the Ozone Layer is an annual holiday dedicated to the protection of the protective ozone layer (or World Ozone Day). This component of the planet is in no way inferior in its importance to the atmosphere, which provides the necessary conditions for life. Officially approved by the UN General Assembly in 1994. Celebrated on September 16th.

History

The Earth’s ozone layer is a gaseous envelope that absorbs excess solar ultraviolet radiation. Acts as a natural regulator of the temperature regime of the planet.

The question of the necessity and role of the ozone layer began to be actively studied in the 20th century. The results of a study in the 1970s showed that the protective layer is gradually becoming thinner, and in some of its places “holes” are observed. They were found over the Arctic and Antarctica. This location is explained by the fact that acid clouds accumulate over the poles, formed from toxic substances released as a result of human industrial activity.

In 1985, the Vienna Convention was signed, according to which 28 countries pledged to participate in large-scale research. Their goal is to identify ways to slow down or stop the destruction of the ozone layer. In 1987, a list of harmful substances used in production was presented. The rejection of them made it possible to significantly slow down the destructive processes. Research in this area is still ongoing.

Interesting facts

• The thickness of the ozone layer does not exceed 3 mm.
• The aroma of ozone can be felt during a thunderstorm.
• During the First World War, this gas was used as a disinfectant.
