Protecting the Ozone layer: Safeguarding the Environment

We know that the earth’s ozone layer protects all of us from the harmful radiations from the sun. But have we ever thought of ozone as toxic? The reports state that the ozone on the ground layer poses health hazards while ozone on stratosphere protects us from harmful UV rays. Recently, the depletion of the ozone layer has become a rising issue that needs to be taken seriously. But also the excess of ozone produced in the lower strata also poses a huge threat to life on earth. The capitalistic and materialist mentality of people had turned blind toward the urgent call for environment protection. One such result of the unchecked human exploitation is the depletion of necessary ozone in the stratosphere, the upper layer of atmosphere and production of excessive ozone on the troposphere, the lower layer of atmosphere.

Effects of Ozone layer depletion


The sun emits electromagnetic radiations at various wavelength. That indicates that the intensities of various energies differ from each other. And atmosphere act as a shield that protects the earth from dangerous radiations.


Ozone is found in two parts of the atmosphere. It is found in the stratosphere that can be called good oxygen. This ozone absorbs the UV radiations and thus prevents dangerous UV rays from hitting the earth’s surface. The depletion of the stratospheric ozone is a serious issue as this results in harmful UV radiation reaching the earth’s surface.

  • This can cause health problems varying from eye disease; development of cataract to skin cancer and immune system damage.

  • UV radiation affects the growth of plants- It can cause a change in the plant’s form, distribution of nutrients within the plants, the development phases and secondary metabolisms. These changes can result in plant diseases and their biochemical cycles.

  • The core of the aquatic food web is phytoplankton. There has been reported a direct decrease in phytoplankton production as the UV radiation increases.

  • The UV radiation damages the development stages of fishes and other marine animals and can destroy the balance of the whole of the aquatic food chain.

  • It can affect the biochemical cycles of terrestrial and marine lives, both of which acts as a sink of greenhouse gases. This can contribute to the concentration of these gases in the atmosphere.

Human activities have a huge role in the reduction of the ozone layer. The decrease in ozone is related to the increasing levels of chlorine and bromine in the stratosphere. They are produced mainly during the manufacturing and release of CFC’s and other halocarbons. These gases are released during the use of refrigerators, air conditioners, a propellant for aerosol cans etc. Controlled use of such products and buying produces that do not use CFC’s can to an extent reduces the depletion of the ozone layer.

Effects of production of excessive ozone on the troposphere


The other layer of ozone is found in the troposphere. This ozone is considered as bad and is not good for human health and it consists of particles of smog. This ozone is man-made. It is the product of air pollution from various industries and automobiles. The emission from the power plants and other sources release nitrogen oxide and other volatile organic compounds. Nitrogen gases and these compounds combine with an oxygen molecule to form ozone at high-temperature conditions.

Thus we are lucky that we are shaded from the harmful ultraviolet radiation by earth’s own sunscreen-the ozone layer. But at the same time, it is helpful when it is miles away from us.


Do you care about the environment? Wish to make a change? Have an idea to resolve issues? ELP is your chance.


We are excited to launch our first edition of the Ecochirp Launchpad program 2020 (ELP2020). ELP is the game-changer for all the budding enviropreneurs. It is a 12 weeks launchpad program for youth-led environmental solutions. This virtual launchpad program with weekly learning modules that includes webinars, mentoring sessions, and weekly tasks that will support you to launch your idea into a validated business plan.
