Its significant innovations include automatic provisions for review—these have led to a ratcheting up of the agreement—and funding by rich nations for adaptations by poorer nations. Increased exposure to UV rays can lead to weakening of the response of immune system and even impairment of the immune system in extreme cases.
By absorbing UV radiation the ozone layer heats up the atmosphere. After the discovery of CFC problem in mid seventies, ozone destruction by active chlorine lO has become a dominating question.
Development of the phenomenon occurred parallel to the Thinning of ozone layer essay of the atmospheric chlorine content produced by the emission of CFCs. Ozone is a gas in the lower level of stratosphere.
The ozone destroying processes in that region influence the ozone, region of the whole southern hemisphere. These combine quickly with an oxygen molecule to form ozone. Under this protocol a global fund is established to aid those developing nations who cannot afford technological costs for alternative chemicals.
Global consumption of CFCs estimated in accounts to 1. UV radiations cause irritation and develop red patches on skin. The London amendment to the Montreal Protocol was signed in May and came into effect on 10 August, UV rays also have adverse effect on the marine ecosystem.
There has been also a lot of research to find out possible solutions to this problem. Direct exposure to UV rays can lead to Cataract problems, and also Photokeratitis or snow blindness.
Ozone has been the most reactive form of molecular oxygen and the fourth most powerful oxidizing agent. Prior to the NAS report, environmentalists had put the ozone problem at the top of their list, and in the United States and several other countries moved to eliminate the use of CFCs in aerosol spray cans.
If the ozone layer is not there, the harmful ultraviolet rays will reach to the lower atmosphere and its temperature will rise to that extent that the biological furnace of the biosphere will turn into a blast furnace.
For the ozone layer to return to its natural state, the chlorine loading which is presently 3 ppbv has to be brought down to a level below 2 ppbv.
In the absence of any other disturbances, O3 settles into a dynamic steady state in which the rate of its formation is equal to the rate of its destruction. Science and Politics in Global Environmental Cooperation. Ozone is a colourless gas which is found in the stratosphere of our upper atmosphere.
It was thus realized that there is a growing probability of damage to Thinning of ozone layer essay layer by human activities. The absorbed heat causes a temperature inversion between 15 to 50 km. There had been a lot of research on this topic over these years to find out all the possible causes that lead to this problem and the effects of ozone depletion.
Pre values, to the left of the vertical dashed line, are often used as a benchmark for ozone and UV recover. Calculations suggested a global ozone loss of 5 to 7 percent bywith attendant increases in skin cancer, probable damage to human and animal DNA, as well as harmful effects on some crops. The Protocol was initially adopted on 11 December, in Kyoto, Japan, and entered into force on 16 February, Due to the presence of UV light, these gases dissociate and release chlorine atom, which then leads to O3 destruction.
There are many other substances that lead to ozone layer depletion such as hydro chlorofluorocarbons HCFCs and volatile organic compounds VOCs.
UV rays will also affect the plants. CFCs released up to amount to 15 million tones. Where scientists had expected a steady and relatively slow depletion of ozone, this crater in the ozone column was so shocking that it took just 2 years to forge an international agreement.
In spite of being a trace gas, it plays a major role in the maintenance of climate and biology of earth. It is present in traces less than 1 ppm in the atmosphere. This example Ozone Layer Essay is published for educational and informational purposes only. Saving the ozone layer: Anthropogenic damage to the ozone layer: For the protection of ozone layer, Vienna Conference in March, was held.Disclaimer: This essay has been submitted by a student.
This is not an example of the work written by our professional essay writers. This agreement was implemented to decrease CFC levels in order to help protect the thinning ozone layer. Clearly, ozone depletion is a dangerous problem due to possible disease outbreaks and famine as a.
Essay on Effects of Ozone Layer Depletion. Article shared by. The upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere.
Ozone layer is a protective stratospheric layer, also known as ozone umbrella. Here is your essay on ozone layer depletion! Ozone (O 3) is a triatomic form of oxygen. It is found largely in the stratosphere that extends from about 6 km at the poles and 17 km at the equator to about 50 km above the earth’s surface.
You've likely heard about the ozone hole or thinning of the ozone layer, but you may not know what causes these problems. These discoveries came about through many years of scientific research, so. Essay on Depletion of Ozone Layer!
Ozone is a gas in the lower level of stratosphere. It is a kind of super-charged oxygen (O 3). It makes a layer in the atmosphere which acts as a cover to the Earth against ultraviolet radiation of the Sun.
The canopy of ozone layer is with variable extent less. The ozone layer is one layer of the stratosphere, the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet.
The stratosphere is the mass of protective gases clinging to our planet.Download
