If the ozone layer is destroyed then powerful ultriviolent rays will penitrate the earth and everyone would get skin cancer and eventually die. It's stable composition made it an excellent substance for many different purposes. Countries around the world including United States have seen the threats created by ozone depletion and agreed to a treat called the Montreal Protocol Essay on ozone layer conservation Best essay on need for conservation of ozone layer The prolonged cumulative exposure to UV-B rays causes skin-cancer, basal layer carcinoma, squamous cell carcinoma essay malignant melanoma etc.
Once exposed to the UV radiation the bond that holds the chlorine containing compounds together would be broken by the rays.
The overall reduction in the 03 layer is now estimated to be about 8 per cent. This new period of less stable climate we have entered, is likely to cause widespread economic, social, and environmental dislocation. There are on the other hand natural ozone depletes such as volcanic eruptions.
The bromine and fluorine in these chemicals act as catalysts, reforming ozone O3 molecules and monatomic oxygen into molecular oxygen O2.
The overabundance of these gases, particularly CO2, in the lower atmosphere, has led to increased absorption of infrared radiation. The Montreal Protocol The theme for World Ozone Day is a motivational rallying call urging all of us to carry on with the exemplary work of protecting the ozone layer and the climate under the Montreal Protocol.
Scientific research has only began to discover the impacts of UV radiation, however, what we do know should be enough for action. The earth which sustains us is in need of loving care.
Moreover, some of these skin cancers can result in death. Damage to the earth's ozone layer began to occur as the levels of these gases in the atmosphere increased. It is already responding to the harm we have inflicted on it.
Ozone levels have dropped by a worldwide average of about 4 percent since the late s. Environment term papers Disclaimer: However, a molecule of ozone is made up of three atoms of oxygen bonded together, therefore, O3, represents ozone.
Over time, winds have transported them into the stratosphere where they have been subjected to high levels of radiation. Due to the Montreal Protocol signed in in which of the world 's nations joined together in banning CFCs and in an initiative to try to off-set any further effects due to emissions of gases that deplete the Ozone there are many recent reports that the hole in the Ozone layer is becoming smaller.
Most of the time, the O atom created by Ozone breakup recombines with one of the plentiful O molecules to re-form O. We must think long term and act now. Moreover, UV rays cause other eye injures including photokeratitis, also known as sun blindness or snow blindness, damage to the retina, and intraocular melanoma tumors.
Similarly, the invention of the automobile made travel easier and quicker. Chlorofluorocarbons CFCs are man-made substances which, for more than 50 years, were considered to be miracle substances because they were virtually non-toxic, nonflammable, and inexpensive to produce.
In the stratosphere, Cfcs would be exposed to UV radiation. With the destruction of ozone molecules, comes more destructive UV rays. Several other Cfcs work well as aerosol propellants, in manufacturing foam, and in making Styrofoam containers.
Malignant melanoma effects the pigment cell in the skin which can spread rapidly to the blood and lymphatic system. In they published a paper which outlines their concerns and findings on Cfcs.
The Heat is On. The sun has a wide range of wavelengths. Scientists have noticed a significant decrease in fish and seabird populations.
This process helps to maintain a steady temperature on the earth. Its presence in the stratosphere protects life on earth by arresting ultra-violet preservation of ozone layer essay and its presence in troposphere affects life on earth as a greenhouse gases. Moreover, Cfcs are considered to be chemically unreactive, or stable.
They have done all that efforts for the safe country and better atmosphere. Plants are dying from the UV exposure. The free Environment research paper The Destruction of the Ozone Layer essay presented on this page should not be viewed as a sample of our on-line writing service.
In SeptemberMontreal Protocol was held for control measure of the ozone layer and it was followed by the Kyoto Protocol of Altitude 1 This is what is normally known as the "ozone layer". Two of the more common objections are: Some pollutants in the atmosphere like Chlorofluoro-carbons CH3 cause the depletion of ozone layer.
Nitrogen oxides and methane are also compounds which adversely affect the stratosphere's ozone. Medical studies have quantified some of the expected effects of increased UV-B levels, based on real-life information form people exposed to greater than average UV-B levels--populations living at high altitudes and in the tropics, where the average ozone layer is thinner and the sunlight more direct.Essay On Ozone Layer Depletion and Protection What is Ozone layer.
Ozone is a triatomic form of the oxygen gas.
It is the lower level of stratosphere. It is a kind of super-charged oxygen (O3). September 16 is declared as the International Day for preservation of ozone by the Montreal Protocol (). Conclusion.
Preservation of ozone layer essay. Ozone lost versus ozone gained. It was also established that one molecule of CFC is capable of destroying 1 lakh ozone molecules.
The overall reduction in the 03 layer is now estimated to be about 8 per cent. These rays cause harmful effect to living beings on the Earth. Ozone Layer Depletion Term Paper: Ozone layer depletion is the decrease of the concentration of ozone in the ozone layer of Earth.
Environment term papers (paper ) on The Destruction of the Ozone Layer: INTRODUCTION In the beginning man lived simply and harmoniously with earth.
However, as time progressed mankind's thirst for knowledge and more eco. The Ozone Layer In environmental science the green house effect is a common term for the role water vapor; carbon dioxide and ozone play in keeping the earth’s surface warmer than it would normally be.
September 16 was designated by the United Nations General Assembly as the International Day for the Preservation of the Ozone Layer. This designation had been made on December 19,in commemoration of the date, inon which nations signed the Montreal Protocol on Substances that Deplete the Ozone Layer.Download
