World Ozone Day
Life on Earth would not be possible without sunlight. But the energy emanating from the sun would be too much for life on Earth to thrive were it not for the ozone layer. https://ozone.unep.org/ozone-day/ozone-life-35-years-ozone-layer-protection
The depletion of the ozone layer is one of the most important environmental problems that we all face in the world. The ozone hole is not really a hole. Ozone is a thinning of the layer. Because of chemicals that are used in our daily lives, the ozone layer is getting thinner. These chemicals are used in our daily lives and they damage the ozone layer.
