The International Day for the Protection of the Ozone Layer, known as World Ozone Day, falls on September 16 of each year and commemorates the day the Montreal Protocol to Reduce Ozone Depleting Substances was signed in 1987. Ask for specific topics to protect and sustain the ozone layer. The theme for 2020 is “Ozone for Life – 35 years of protecting the ozone layer”. The ozone layer protects the earth from most of the sun’s harmful ultraviolet rays.
In the late 1970s, scientists discovered that ozone-depleting substances used in aerosols and refrigerants in refrigerators and air conditioners leave holes in this protective shield known as ozone holes. This hole allowed harmful UV rays to penetrate the ozone layer, increasing cases of skin cancer and cataracts, damaging crops, crops and ecosystems. passed the Vienna Convention for Under this treaty, governments, scientists and industry worked together to eliminate his 99% of all ozone-depleting substances. Thanks to the Montreal Protocol, the ozone layer is healing and is expected to recover almost completely by 2050.
In support of the protocol, the Kigali Amendment, which entered into force in 2019, will work to reduce the use of hydrofluorocarbons, gases with high global warming potential. One of the main reasons for the success of the Montreal Protocol is the availability of high-quality science to improve our understanding of not only the causes and mechanisms of ozone depletion, but also the potential environmental impacts of these atmospheric changes. It was a foundation based on Because of the direct involvement of the Montreal Protocol in mitigating climate change, and the strong physical and biological links that exist between stratospheric ozone depletion and the impacts of climate change.
The Environmental Effects Assessment Panel necessarily addresses the consequences of ozone depletion in the context of a changing global climate. The theme of this year’s World Ozone Day is Montreal Protocol@35: global cooperation protecting life on earth. Ozone layer was discovered in 1913 by the French physicists Charles Fabry and Hanri Buisson. Measurements of the sun showed that the radiation sent out from its surface and reaching the ground on Earth is usually consistent with the spectrum of a black body with a temperature in the range of 5,500 – 6,ooo K, except that there was no radiation below a wavelength of about 310 nm at the ultraviolet end of the spectrum. It was deduced that the missing radiation was being absorbed by something in the atmosphere. Eventually the spectrum of the missing radiation was matched to only one known chemical, Ozone. Higher exposure to UV radiation increases the incidence of skin cancers and other UV, induced human diseases, such as cataracts and photosensitivity disorders. Increases in the incidence of skin cancer over the last century appear largely attributable to changes in behaviour that increase exposure to UV radiation. 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.
Edu world celebrates the ozone day to spread awareness about the protection of ozone layer and undertake green measures in the campus to reduce the depletion of the ozone layer. Phasing out the controlled use and associated reductions of ozone-depleting substances has not only helped protect the ozone layer for present and future generations, but has also helped the world fight climate change. It also made a significant contribution to these efforts. In addition, it has protected human health and ecosystems by blocking harmful UV rays from reaching the earth.
