International Day for the Preservation of the Ozone Layer: 16th September, 2020

International Day for the Preservation of the Ozone Layer: 16th September, 2020

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.

Ozone for life: 35 years of ozone layer protection


This year, we celebrate 35 years of the Vienna Convention and 35 years of global ozone layer protection. 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. This stratospheric layer shields Earth from most of the sun’s harmful ultraviolet radiation. Sunlight makes life possible, but the ozone layer makes life as we know it possible.

Protecting the Ozone Layer

*   Minimize high altitude aircrafts (oxygen reduction and water vapour deposition)*

*   Minimize rocket flight (water vapour deposition)

*   Encourage growth of plants that produce oxygen

*   Discourage deforestation

*   Decrease/ control release of known ozone depleting chemicals

*   Use eco-friendly household cleaning products

*   Avoid using pesticides

*   Banning the use of dangerous nitrous oxide

*   Use products that are labelled “Ozone friendly” or “CFC free”
