World Ozone Day 2020

In this era of technology, human beings are destroying everything that is becoming more harmful to their path of progress. Similarly, for his comfort and convenience, man is determined to destroy the ozone layer which protects him from the dangerous ultraviolet rays emanating from the sun. Today, due to the increasing industrial activities, the ozone layer which saves our life has become a threat.

What is Ozone Layer?

Ozone is a light blue gas that is a compound of three oxygen atoms (O3). The ozone layer is generally found between 10 km to 50 km above ground level. This gas acts as a good filter for ultraviolet rays emanating from the Sun.

The ozone layer is a part of the atmosphere that has high ozone concentrations. Ozone is a form of gases that is made of three oxygen atoms O3. Depending upon where the ozone layer is, it can either harm life or protect life on Earth. Most of the ozone remains in the stratosphere where it functions as a shield, protecting the planet surface from the dangerous ultraviolet radiation of the sun. We might all be more susceptible to impaired immune systems, cataracts, and skin cancer cells if this shield was to weaken. The ozone can be an unsafe pollutant that triggers damages to plants and lung tissue if it is closer to the Planet than the troposphere, however, which is an atmospheric layer from the surface up to around 10 km. This reveals why the ozone layer is so important, and it is important to manage it properly.

There is a hole in the ozone layer that enables big quantities of ultraviolet light to get in and it is situated on the poles, which is on the Arctic Ocean and the Antarctic continent, being especially large throughout the spring of both hemispheres, causing prolonged summer season. Hole in the ozone layer is more dangerous. Although that it is caused as a result of natural fluctuations, it can also be caused by activities that most of us engage in as humans, which produce gases that end up in the stratosphere, deteriorating the ozone molecules, as well as boosting the impact and size of the hole in the ozone layer. This is a health issue and environmental problem, as excess solar radiation is a threat to any kind of life.

Who discovered ozone layer?

The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. The layer is mainly spotted in the lower portion of the stratosphere, from approximately 15 to 35 kilometres above Our planet, while its thickness varies seasonally and also geographically.

Who discovered ozone layer depletion?

In 1985, Jonathan Shanklin along with co-workers Brian Gardiner and late Joe Farman discovered the “Ozone Hole”. At the time, there was some speculation that spray cans and supersonic jets such as Concorde might be harming the upper atmosphere’s ozone layer that shields us from the sun’s ultra-violet radiation.

In 1985, They reported, unexpected and large decreases in stratospheric ozone levels over the Antarctic locations of Halley and Faraday. Their information showed that, after about two decades of fairly consistent values, ozone levels began dropping in the austral spring months around the late 1970s (Fig. 1). By 1984, the stratospheric ozone layer over Halley in October was only about two-thirds as thick as that seen in earlier decades– a phenomenon that became known as the Antarctic ozone hole. Farman boldly suggested a link to human use compounds called chlorofluorocarbons (CFCs), frequently used in aerosol container and cooling gadgets such as refrigerators. Their findings transformed the areas of atmospheric science and chemical kinetics, and caused worldwide changes in environmental policy.

Causes of ozone layer depletion

Main reason for depletion of Ozone layer is human activity mainly human-made chemicals that contain chlorine or bromine. These chemicals are known as ODS, which is Ozone – Depleting Substances. Since early 1970’s scientists observed decrease in stratospheric ozone and it was found more noticeable in Polar Regions. Do you realize that one molecule of chlorine has the capacity to break down countless ozone molecules. The primary ozone depleting substances include chlorofluorocarbons (CFCs), carbon tetrachloride, hydrochlorofluorocarbons (HCFCs) and methyl chloroform. Halons, in some cases known as brominated fluorocarbons, also contribute mightily to ozone depletion. ODS compounds have a lifetime of about 100 years.

What happens if ozone layer is damaged?

  • The ozone layer is very important, which protects us from the dangerous ultraviolet (ultra violet) rays of the sun. If ozone layer is damaged then all skin related diseases can occur in humans.
  • Without the ozone layer we cannot survive because these rays can cause cancer, damage to crops and threat to marine organisms and the ozone layer protects us from these ultraviolet rays.
  • Another danger is due to the melting of poles. There is a big hole in the ozone in Antarctica. There are large icebergs in the Antarctica region. If these icebergs melt, there can be many hazards including flooding in coastal areas. Apart from this, heat will also increase, which will be harmful.
  • Damage to the ozone layer also affects biological diversity and can destroy many crops. They have an effect on microorganisms. Apart from this, it also affects small plants in the sea, which can reduce the quantity of fish and other animals.

History of world ozone day

Keeping in mind the importance of the ozone layer, work is being done to protect it from the last two decades. on December 19, 1994, in United Nations General Assembly, a resolution was pass to celebrate September 16 as International Ozone Day to bring awareness to the people all over the world. At that time, the goal was to create an ozone friendly environment around the world by 2010. Although the target is still far away, the world has done remarkable work in the direction of saving the ozone layer.

The result of the exercise to protect the ozone layer is that today ozone friendly refrigerators, coolers etc. have come in the market. To protect this layer, it is important that foam mattresses are not used. Use of plastic should be minimized. Room fresheners and chemical perfumes should not be used and ozone friendly refrigerators, air condition only should be used. Apart from this, the design of your house should be done in an ozone friendly manner, using natural sources for light, air and energy.

We have got this earth as a legacy, which we have to give to the coming generation as well. We should take such a path that not only benefits us but also our future generations can enjoy this very beautiful earth.

How to celebrate World Ozone Day?

One of the most effective ways to celebrate World Ozone Day is by finding out more about the ozone layer.

How we can protect the ozone layer?

  • Avoid using harmful gases like CFCs chlorofluorocarbons (CFCs), halogenated hydrocarbon, methyl bromide and also nitrous oxide in various processes.
  • Minimize the use of personal vehicles like cars that releases carbon monoxide gas and nitrogen oxides and also consider public transport consequently saving financial resources and the environment.
  • Save the ozone layer by properly maintain your air conditioning system. If air conditioner are not properly maintained, there are high chances that CFC gas is released into the atmosphere.
  • People should also stay away from using cosmetics, hair sprays, room fresheners as these products release Chlorofluorocarbons (CFCs).
  • Several greenhouse gases are produced during the production of chemical fertilizers. Hence, we should avoid the use of fertilizers in agriculture and switch them with organic ones.
