Life on Earth would be completely different if it were not protected by a thin three-millimeter ozone layer.

If the ozone layer disappears, then life, if preserved, is only deep underwater in the World Ocean or underground.

Depletion of the ozone layer leads to an increase in the amount of UV radiation reaching the Earth. This, in turn, has disastrous consequences for living organisms.

It is believed that the share of the halogen pathway for the decay of stratospheric ozone has increased as a result of human activities, which has led to the formation of ozone holes.

The International Day for the Protection of the Ozone Layer was proclaimed by the UN General Assembly in 1994.

The date of the International Day was chosen in memory of the date of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer.

In March 1985, at the international meeting in Vienna, a framework agreement was adopted – the concept of preserving the ozone layer, called the Vienna Convention.

The Montreal Protocol was developed in accordance with the Vienna Convention, signed on September 16, 1987 in Montreal (Canada) and entered into force on January 1, 1989.

The purpose of the protocol is to protect the ozone layer by reducing (or stopping) the production and consumption of certain chemicals that destroy the ozone layer.

A study conducted under the auspices of the United Nations Environment Program shows that the ozone layer of the Earth is beginning to recover.

If the countries that have signed the protocol will stick to it in the future, it can be hoped that the ozone layer will be restored by 2050.

States were invited to dedicate this Day to advocacy of activities in accordance with the objectives of the Protocol and its amendments.

At the Department of Quality Management of the NuPh these days lectures devoted to the protection of the ozone layer of the earth, propaganda of activities in accordance with the objectives of the Montreal Protocol and amendments to it are traditionally read.
