International day of the ozone layer.
The ozone layer is endangered by the use of certain chemicals over the years.
Praised be You, my Lord, for brother wind and for the air, and the cloud and the serene sky, and at all times, through all of them you give sustenance to your creatures.
A joint international effort has allowed the elimination and reduction of the use of these substances that depleted the ozone layer and today the ultraviolet radiation from the sun that reaches the Earth has been considerably reduced, protecting human health and ecosystems.
But our effort must continue with significant and daily gestures, and with demands to comply with international agreements.
