International Day for the Preservation of the Ozone Layer

Today, 16 September, marks the International Day for the Preservation of the Ozone Layer.

With the aim of preserving the ozone layer, which works as a natural shield for the planet against the ultraviolet radiation emitted by the sun, the Montreal Protocol was established on 16 September 1987. This is an international agreement which has been signed by 191 countries.With the signing of the agreement, 16 September became the International Day for the Preservation of the Ozone Layer.

The ozone layer is a thin envelope formed by the gas ozone (O3) which surrounds the earth and protects living organisms from the radiation emitted by the sun. Without this layer, located 25 to 30 kms above the surface (stratosphere), the existence of life on our planet would not be possible.

The reduced thickness of the ozone layer is a serious problem for human beings. In the regions where this reduction is noted, there is a greater incidence of allergies and eye problems, such as cataracts and blindness, and skin problems such as cancer. Furthermore, the radiation also affects plants and other living beings. Small actions such as the recycling of materials, reduction in the use of plastics, and planting trees could help protect the ozone layer.

Do your part, and contribute to the preservation of our planet!
