16th Sep: International Day for the Preservation of the Ozone Layer
The United Nations' (UN) International Day for the Preservation of the Ozone Layer is celebrated on September 16 every year. This event commemorates the date of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. 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 phase out 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.
On this day primary and secondary school educators throughout the world organize classroom activities that focus on topics related to the ozone layer, climate change and ozone depletion. Some teachers use educational packages from the UN Environment Programme (UNEP) that have been specifically tailored to address topics about the Earth's ozone layer.
Other activities that are organized by different community groups, individuals, schools and local organizations across the world include: the promotion of ozone-friendly products; special programs and events on saving the ozone layer; the distribution of the UNEP's public awareness posters to be used for events centered on the International Day for the Preservation of the Ozone Layer; and the distribution of awards to those who worked hard to protect the Earth's ozone layer.
