The effect of ozone depletion is more than what one would anticipate. This paper analyses the causes and effects of ozone depletion. Causes of ozone depletion “The fact that the ozone layer was being depleted was discovered in the mid-1980s. The main cause of this is the release of CFCs, chlorofluorocarbons”(Ozone depletion, n. d). Ozone layer is present in the stratosphere. Majority of the refrigerators and sprays used by us contains CFC in one form or other. When we dispose these things injudiciously, CFC gets liberated from these things and reaches the stratosphere. At stratosphere, CFC’s will react with ultraviolet radiations and liberate chlorine gas. Chlorine is a highly reactive gas and it will react with Ozone (O3) and liberates oxygen (O2) molecules. Because of the high reactivity of Chlorine, each chlorine atom can destroy more than hundred thousand ozone molecules. Thus increased presence of Chlorine in stratosphere is the major reason for the depletion of ozone layer. Even though chlorine is produced from different other manmade activities, none of those chlorine reaches stratosphere because of its high solubility with water. These Chlorine atoms have the ability to reach only up to the troposphere in which it forces to combine with the rain water. “In contrast, CFCs are very stable and do not dissolve in rain. There are no natural processes that remove the CFCs from the lower atmosphere. Over time, winds drive the CFCs into the stratosphere”(Sources of ozone depletion, n. d) “Large volcanic eruptions can have an indirect effect on ozone levels. Volcanic eruptions can produce large amounts of particles called aerosols. These aerosols increase chlorine’s effectiveness at destroying ozone” (Sources of ozone depletion, n. d). Aerosols contains large amount of CFC’s which can reach up to the stratosphere. Apart from CFC, oxides of nitrogen also cause damages to Ozone layer. Supersonic Aircrafts and space shuttles liberate oxides of nitrogen which will react with ozone layer and liberate oxygen molecules. The widespread use of artificial fertilizers may also release nitrogen oxides into the stratosphere, although this potential effect is not yet fully defined (Sources of ozone depletion, n. d).Nitrogen is one of the major contents of the chemical fertilizers. It can react with oxygen and form different oxides of nitrogen. These gases have the capacity to reach even stratosphere even though the scientific proofs are not there. Effects of ozone depletion Ozone layer depletion will increase the amount of ultraviolet radiations reaching on earth. Increased exposure to ultraviolet rays may cause chronic skin cancers like Malignant Melanoma among human beings. “Every time 1% of the ozone layer is depleted, 2% more UV-B is able to reach the surface of the planet. UV-B increase is one of the most harmful consequences of ozone depletion because it can cause skin cancer” (Ozone depletion: effects, n. d). Birth defects, visual defects, lung diseases malaria etc are other diseases which can be increased among humans as a result of the increased exposure to ultraviolet radiations. Ultraviolet radiations can cause damages to plant lives also. The natural immunity of the plants could be damaged as a result of the increased exposure of ultraviolet radiations. As a result of that yields from the agricultural crops
Causes and effects of Ozone Depletion Causes and effects of Ozone Depletion In every year, September 16 th is celebrated as the Ozone day by us. Even though oxygen is responsible for sustaining our lives on earth, no Oxygen day celebration is taking place in this world…
It is true that human activities contribute to the primary reason behind ozone loss, but it is also evident that the independence of the chemical processes also formed the dominant source of ozone loss. While ozone loss is very likely to result in climate disruption, it is also true that a significant section of certain objects like fossils have also been destroyed by the loss of ozone.
Man borrows form the resources available on earth and exploit them to his advantage for sometime before transferring them to some other part of the world or to process and utilize them through reformulation. However the idea is to minimize these harmful forms by adopting sustainable methods of discharging the wastes (Jorgensen & Johnsen, 1989, 30).
Likewise, millions of tonnes of wastewaters containing potentially harmful pollutants find their way into water bodies and underground water aquifers. Several bodies have been initiated with the main aim of conserving environment. Some of these bodies in clued NEMA, Centre for Sustainable Development and others.
The direct effect is evident to anyone who has lived in or near a major city. The skies are off-color and ozone warnings are common. People who are susceptible to lung-related issues such as asthma or are elderly are warmed not venture outside on those days.
As the paper stresses the book takes note of world population, pollution, food production, industrialization, and resource depletion as the results contributed and affected by the exponential growth of the entire industry. The book Limits to growth: the 30-Year Update examines that industrial production, food production and etc.
The author highlights that deliberation of worldwide climatic-environmental threats to human society’s well-being has a dominant role to perform. Climate variation is likely to upset health through several indirect paths: the forms of communicable diseases; the food-producing schemes; the accessibility of freshwater; and damage to ecology.
Therefore, the team responsible for the development of this new corporate Web site must possess several programming skills specific to the task, in order to ensure the success of the project. One of the programming skills that the team members should have is attention to details.
However, great strides in technology have been made since the early days of the Industrial Revolution, and the sudden rise in economic activity has caused an industrialization and mechanization that was unparalleled in the entire history of
