World Ozone Day 2021: Know Theme, History and About the Ozone Layer

World Ozone Day is otherwise called International Day for the Preservation of the Ozone Layer. The ozone layer is a safeguard of gas that protects the Earth from the harmful rays of the Sun and helps in preserving life in the world.

World Ozone Day is seen on 16 September yearly. The day helps the marking to remember the Montreal Protocol on substances that drains the Ozone Layer. On this day individuals from everywhere the world are relied upon to join the Montreal protocol for talks and seminars.

Life is preposterous on Earth without the ozone layer. It is found in the upper layers of the atmosphere and is an exceptionally reactive gas. It protects life on Earth by retaining Sun’s harmful ultraviolet radiation as is otherwise called Ozone Shield. Bright beams can cause a few skin diseases.

Theme of World Ozone Day 2021:

The subject of World Ozone Day 2021 is ‘Montreal Protocol – keeping us, our food, and vaccines cool’. According to the UN, this year the day highlights, Montreal Protocol accomplishes such a great deal more like slowing climate change and assisting with boosting energy productivity in the cooling sector, which adds to food security.

History of World Ozone Day:

On 22 March 1985, the Vienna Convention for the Protection of the Ozone Layer was adopted and signed by 28 countries. The Montreal Protocol was endorsed on 16 September, 1987 on substances that drain the Ozone Layer and denotes the International Day for the Preservation of the Ozone Layer. Joined Nations General Assembly in its goal 49/114 out of 1987 picks this day. Essentially, it is a worldwide arrangement intended to secure the ozone layer by lessening the creation of substances expected to be answerable for ozone layer depletion. Allow us to reveal to you that the Montreal Protocol was carried out on 1 January, 1989.

In 1994, the United Nations General Assembly broadcasted 16 September the International Day for the Preservation of the Ozone Layer, celebrating the date of the marking, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer (goal 49/114).

In 2012, the twentieth commemoration of the Montreal protocol was celebrated. Additionally, on this day Educators teach their students the benefits of the Ozone layer, and extraordinary occasions and exercises are coordinated to spread awareness.

The Vienna Convention and the Montreal Protocol turned into the first treaties throughout the history of the United Nations to achieve universal ratification on 16 September, 2009.

About Ozone Layer:

We as a whole realize that ozone protects us from UV rays coming from the sun. In 1957, Professor Gordon Dobson of Oxford University found the ozone layer. Ozone is comprised of three molecules of oxygen. It is a profoundly receptive gas and is addressed by O3. It happens normally just as a man-made product in the Earth’s upper atmosphere,i.e. stratosphere and lower atmosphere,i.e. lower atmosphere. That is the Ozone layer is available in Earth’s environment (15-35km above Earth) in the lower piece of the stratosphere and has somewhat high centralizations of ozone (O3). Normally, it is shaped through the interactions of solar ultraviolet (UV) radiation with sub-atomic oxygen O2. It lessens the unsafe UV radiation arriving at the Earth’s surface.

Be that as it may, at the ground level ozone is viewed as a significant air toxin. We as a whole realize that ozone shields us from unsafe UV radiation yet ozone at ground level is hazardous and causes pollution. Because of human activities, the ozone layer is getting exhausted in the world which could be extremely disastrous. It likewise causes photochemical smog and acid rain.
