World Ozone Day or the International Day for the preservation of the Ozone Layer is observed on the 16th of September. The day aims to create awareness about the importance and need of the Ozone layer which is the single protection on Earth against UV rays coming out from the sun. The UN Environment Programme also aims to bring awareness about the importance of getting rid of the substances that damage the ozone layer. It also calls for taking time-targeted actions to protect Earth’s protective shield.

What is Ozone Layer?
The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the rays of the sun, thus helping preserve life on the planet. The phaseout of controlled uses of ozone depleting substances and the related reductions have not only helped protect the ozone layer for this and future generations, but have also contributed significantly to global efforts to address climate change; furthermore, it has protected human health and ecosystems by limiting the harmful ultraviolet radiation from reaching the Earth.
