World Ozone Day 2020: Why Ozone layer should be protected?

World Ozone Day 2020
72 / 100

The International Day for the Preservation of the Ozone Layer or World Ozone Day 2020 is celebrated every year on 16 September. This year, we are celebrating 35 years of the Vienna Convention and 35 years of global ozone layer protection day. The main aim of this day is to spread awareness about ways that are effective in protecting the ozone layer.

The theme for the World Ozone Day 2020 is ‘Ozone for Life’ which reminds us that not only Ozone is important for life on Earth, but also acts as a reminder that we need to protect the ozone layer for our future generations as well.

From our school days, we have learned how the Ozone layer acts as a protective shield against the ultraviolet radiation (UV) rays emitted by the sun that has the potential to cause skin cancer and cataract. The UV rays can also cause significant damage not only to humans but also to plant and marine life.

In 1970 the scientist discovered that humanity was creating a hole in Ozone protective shield. The hole in the Ozone layer has been caused by depleting gases (ODSs) used in aerosols and cooling, such as refrigerators and air-conditioners said the scientist.

In 1985 the governments of the world adopted the Vienna Convention for the Protection of the Ozone Layer and in 1987, under the Montreal Protocol the governments, scientists and industry worked together to cut out 99 per cent of all ozone-depleting substances.

According to the United Nations Environment Programme (UNEP), the ozone layer is recovering and expected to return to pre-1980 values by mid-century.

The Kigali Amendment, which came into force in 2019, and the Montreal Protocol will work together for reducing hydrofluorocarbon (HFCs) and greenhouse gases that have climate-warming potential and are damaging to the environment.

Various Ways To Protect Ozone Layer

The most important ways to protect the ozone layer is to avoid as much as possible using harmful gases like CFCs chlorofluorocarbons (CFCs), halogenated hydrocarbon, methyl bromide and nitrous oxide in various processes.

Minimising the use of personal vehicles like cars that releases carbon monoxide and nitrogen oxides and resort to public transport thereby saving financial resources and the environment.

If AC is not properly maintained, then there are high chances that CFC gas is released into the atmosphere.

As much as possible people should also avoid using cosmetics, hair sprays, room fresheners as these products release Chlorofluorocarbons (CFCs).

Several greenhouse gases are produced during the manufacturing of chemical fertilisers so we have to avoid the use of fertilisers in agriculture and replace them with organic ones.
