Increased solar radiation was predicted to cause higher rates of certain cancers in many species, to be detrimental to the development of certain bacteria some vital to agriculture , and to cause cortical cataracts. Ozone depletion. The last problem you would think of is the depletion of the ozone layer. However, it could be the most serious problem we are facing today.
This layer of gas is slowly diminishing each day, and causes a great concern to our safety. There are many reasons why this depletion is occurring, and chemistry is playing a huge role into helping solve this problem. Ozone composed of three oxygen atoms is an extremely. During the 21st century, the media have been upbeat about information regarding the destruction of the environment. Of major concern are the effects of human activities in destroying the ozone layer Ryding The ozone layer is a thick layer of air covering the earth.
It is located in the stratosphere 10 to 15 kilometers above the earth. The ozone layer consists of two layers. Ozone Depletion Atmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light.
However, industrial. Ozone depletion directly affects society and the environment through increased exposure to UV radiation on humans, animals, plants and materials. Increased exposure to UV radiation can have serious adverse side effects for humans: Skin Cancer UV-B radiation can cause benign and malignant skin melanomas. A reduction in ozone levels increases the amount of UV-B radiation that can reach earths surface which would cause an increase in the number of occurrences of skin cancers, sunburns and premature.
Many people fail to realize that our species is the reason this planet is dying. Increasing populations mean a higher demand for resources which will not be here forever. Pollution begins with the emission of greenhouse gasses into the atmosphere, mostly CO2. These gasses begin to deplete the ozone layer which is the layer that is protecting the planet from the harmful sun rays. The ozone layer. Warming and Ozone Depletion Global warming is a gradual increase in the overall temperature of the Earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide , chlorofluorocarbons and other pollutants.
One of the biggest issues that is currently taking place in global warming is depletion of the ozone layer and human activities are part of the blame. Ozone is super-charged oxygen in the lower level of the stratosphere. It makes a layer in the air, which goes about as a spread to the Earth against the bright radiation of the Sun. The ozone layer's shelter is with a variable degree less thick close to the outside of the Earth contrasted with the tallness of 30km. This depletion of Ozone layer essay explains the causes and effects of its depletion.
Ozone layer consumption is the diminishing of the ozone layer present in the upper air. This happens when the chlorine and bromine iotas in the environment interact with ozone and crush the ozone atoms. One chlorine can pulverize , atoms of ozone. It is devastated more rapidly than it is made. A few mixes discharge chlorine and bromine on presentation to high bright light, which at that point adds to the ozone layer consumption. Such mixes are known as Ozone Depleting Substances.
This essay on ozone layer in English states the most important causes of ozone depletion. A few contaminations in the environment like chlorofluorocarbons CH 3 cause the exhaustion of the ozone layer. These CFCs and other comparable gases, when reaching the stratosphere they are separated by the bright radiation, and accordingly, the free particles of chlorine or bromine. These molecules are profoundly responsive to ozone and disturb the stratospheric science.
The responses drain the ozone layer. Researchers state that the unregulated dispatching of rockets brings about substantially more exhaustion of the ozone layer than the CFCs do. If not controlled, this may bring about a tremendous loss of the ozone layer constantly by The depletion of ozone layer essay also provides the following effects of the depletion. Because of the consumption of the ozone layer, the Earth is presented to ultra-disregard radiation.
These beams cause a harmful impact on living creatures on the Earth. It influences the cycle of photosynthesis in plants. Ascend in the temperature, different skin infections, a decline of invulnerability, and so forth are the plausible outcomes. Direct presentation to bright radiations prompts skin and eye malignant growth in creatures.

Direct presentation to bright radiations prompts skin and eye malignant growth in creatures. Tiny fishes are incredibly influenced by the introduction to destructive bright beams.
These are higher in the amphibian natural way of life. The greater part of the cleaning items has chlorine and bromine, delivering synthetics that discover a route into the air and influence the ozone layer. These ought to be subbed with common items to secure the climate.
The vehicles produce a lot of ozone-depleting substances that lead to a dangerous atmospheric deviation, just as ozone consumption. Along these lines, vehicles' utilization ought to be limited, however much as could be expected. Normal techniques ought to be actualized to dispose of bugs and weeds as opposed to utilizing synthetics.
One can utilize eco-accommodating synthetic compounds to eliminate the nuisances or eliminate the weeds physically. For the security of the ozone layer, the Vienna Conference in March was held. In September , the Montreal Protocol was agreed upon.
Stratospheric cooling leads to the formation of PSCs or polar stratospheric clouds which create ozone holes over Antarctica Fergusson On the other hand, due to the increased presence of CFCs and carbon di-oxide in the atmosphere, the amount of ozone in the troposphere has increased causing the troposphere temperature to go up. According to some scientists, this cycle in long run can increase the greenhouse gas on the earth surface contributing to climate change Sivasakthivel and Reddy Montreal Protocol It was in the early s that scientists through different satellite and ground-based measurements began to realize the thinning out of the ozone layer.
The most affected region by the creation of ozone hole was Antarctica. Upon the realization of the gravity of the situation, the scientific community sought immediate remedial actions in an international convention in Vienna in Sivasakthivel and Reddy This led to the creation of an international treaty in known as Montreal Protocol. Ratified by countries, Montreal Protocol focused on the phase-down of the use of ozone depleting substances like CFCs, methyl chloroform, halons and the like.
Montreal Protocol was a landmark event as it triggered an environmental movement on an international level. For the first time it was decided that all the participating countries were legally liable to reduce the use of CFCs and other ODSs. All the countries agreed that they would try to stop using CFCs and other harmful ozone depleting compounds within a given schedule. However, some relaxation of the rule was applied to developing countries which didn't have monetary arrangement as well as technological advancement to replace CFCs by bringing in new technologies Sivasakthivel and Reddy However, ODSs are quite stable and live in the atmosphere for up years.
Therefore, it will take about few decades more to have the stratospheric ozone layer healed. Besides the policies and agencies trying to prevent ozone depletion, some individual efforts should be taken by every responsible citizen of the world because ozone layer depletion is a global phenomenon that can affect each and every one of us.
Instead of polluting the air through vehicular emissions which create smog contributing to ozone deterioration, we must take public transport or use bicycle for regular commute Green Diary We also should try walking to cover short distance. Furthermore, we must make sure to use eco-friendly and ozone friendly cleaning products that are free of any harmful chemical hazardous to ozone layer.
We must also depend less on pesticides and more on natural resources. There are two differing views on whether the ozone layer can be depleted or not. It is a well-known fact that with the increase in CFCs ozone layer depletes. Most of the scientists believe that even a moderate level of CFCs in the air can completely deplete the ozone layer.
However, many other scientists believe that ozone layer has its own balance and cannot be easily depleted. They are of the view that when ozone layer is depleted then more and more UV rays reach the earth surface and also troposphere heats up. As the temperature of troposphere goes up less and less, CFCs reach ozone layer as they react more easily with other molecules at troposphere Fergusson As less CFCs reach ozone layer, the depletion rate of ozone layer reduces and in fact starts to produce some more ozone.
This process keeps the balance of ozone layer. Ozone layer depletion refers to reduction of the ozone in the stratosphere. Ozone layer depletion triggers an array of harmful effects for human health like skin cancer, sunburn, premature aging and cataract. High level of UV radiation can totally ruin the productivity of aquatic systems by interfering with the photosynthesis process and cause the reduction of bacterioplankton.
Internationally, the Montreal Protocol was the first step taken towards the reduction of ozone depletion by legally binding the participating countries to reduce and stop the production of CFCs and other chemicals harmful to ozone. Though there are some varying opinions among scientists whether or not ozone depletion is possible, most of the scientific researches show that ozone layer depletion is a phenomenon mainly caused by man-made instruments.
Therefore, concerns and cooperation should be shown by all the countries to mitigate this phenomenon. Sivasakthivel, T. Siva Kumar. Ozone Depletion. What is Ozone Depletion?.
