Environment is consists of all living and non-living things in the earth. Things like vegetation, microorganisms, atmosphere, rocks, soils, energy, radiation, air, climate, water, magnetism all comes under natural environmental processes. The main environment is made up of atmosphere, lithosphere, hydrosphere and biosphere. Atmosphere is the blanket of air surrounding the whole earth. There are main five layers on the atmosphere. They are troposphere, stratosphere, mesosphere, ionosphere and lastly exosphere. Apart from all these layers there is an ozone layer which protects the earth from the sun.
Formation of ozone layer:
Ozone layer is a part of earth’s atmosphere. Ozone layer is in the lower part of the stratosphere. Ozone layer protects the earth from the harmful ultraviolet rays of sun. Photochemical mechanisms are the process through which ozone layer is formed. Ozone layer absorbs maximum of the ultraviolet rays from the sun and protects the people from the UVA and UVB rays. Ozone is formed by the ultra violet light with striking the oxygen. Oxygen molecules become single and then again react with unbroken oxygen and forms ozone. Developed science made this great development and saved the earth.
There are many severe health problems due to the ozone depletion. With new technology and science it is found that there is ozone depletion causing many problems like skin cancer, burning of skin, sunstroke’s, etc. These depletion’s can be by the catalysts like nitrous oxide, nitric oxide, hydroxyl, atomic chlorine, atomic bromine and many more. Chlorofluorocarbons and bromofluorocarbons also causes breakdown of thousands of ozone molecules which lead to the poor absorbing capacity of UVA and UVB rays from the sun by the ozone layer. In this way ozone layer is getting depleted day-by-day and thus people are suffering regularly.
Saving the ozone layer:
Now it is extremely essential to protect the ozone layer from depletion. Use of gases which may be harmful to the ozone layer should be banned. There should be release of more new gases that will Eco-friendly and will not harm the ozone layer which in turn may harm the whole mankind. News is there that the CFCs consists of aerosols sprays that is dangerous and extremely harmful to the ozone layer and destroys the ozone layer. But in certain countries CFCs are not yet banned. So it is urgently needed to stop the use of CFCs and the most harmful gas nitric oxide.
Ozone layer is very essential for the protection of earth from the harmful rays of sun. Recent review on the topic shows the importance of the ozone layer. The whole environment has different climatic conditions and weather. Climatic conditions like temperature, rainfall, pressure, etc. may also get affected due to ozone depletion. Ozone depletion also may cause problem in the natural climatic condition of the earth. More info can be gathered from the different article. Any type of gases that causes ozone depletion should be strictly banned and more and more green plants should be planted for the protection of the ozone layer.
