The activity is meant to stimulate reflection on the importance and preservation issues of the Ozone Layer.
The event also focuses on impact of other harmful agents on the atmosphere, thus conditioning the air quality on the earth.
The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone.
Signatory countries signed on 16 September 1987 the Montreal Protocol, an international treaty in which the members are committed to replacing substances that cause damage to the ozone layer to reduce the emission of harmful gases.
The date was declared by the United Nations (UN) and is aimed to warn the world of the need for global, national and regional action to protect the ozone layer.
