Thesis ozone layer depletion
If the ozone layer is depleted by human action, the effects on the planet could be catastrophic. So this goes to prove that at that time human activities contributed very little to Global Warming but it still occurred, this is a good enough indication that it is a natural process which has to occur, the only problem is that the human activities have lately started contributing extensively towards this natural process.
This occurs due to various reasons; one of the most significant is the green house effect.
Essay on ozone layer depletion and protection
The stratosphere reaches 30 miles above the Earth, and at the very top it contains ozone. Of the greenhouse gas, solar irradiance and ozone depletion scenarios, ozone depletion demonstrates the most realistic relative changes with a cooling of the stratosphere and a warming of the troposphere and Earth's surface as has been observed. No human activity is responsible for it. But due to the large emission of the halogens and CFCs ozone is being depleted rapidly Vermishev and Danilov-Danilyan This produces an amplification effect of any warming that occurs. Because air pollution is greatly affecting the ozone, America needs to take immediate steps to stop ozone depletion. These chemicals, although very useful, cause consequences that need to be dealt with now in order to prevent further damage. If the ozone layer is depleted by human action, the effects on the planet could be catastrophic. This paper will throw light upon what the ozone layer is made up of and what can the human beings do to help maintain it? It was until , chlorine was found to be the catalyst which speeds up the ozone depletion.
One chlorine molecule has the capability to break down thousands of ozone molecules. Although factors other than climate may have intensified the severity of some of the events on the map, scientists predict such problems will increase if emissions of heat-trapping gases are not brought under control.
In the s chemists discovered that certain chemicals could travel into the upper atmosphere and damage the protective ozone.
The ozone destroying processes in that region influence the ozone, region of the whole southern hemisphere. Effect on animals In domesticated animals, too much UV radiation could also lead to skin and eye cancer.
The ozone hole develops as result of this process. Global consumption of CFCs estimated in accounts to 1.
Causes of ozone layer depletion
Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. The ozone layer is instrumental in protecting the animals as well as the human beings and its depletion has been constantly on the rise which is not good news for the human beings. It is used as a disinfectant and bleaching agent. Health effects caused by filthy air are also a serious problem that has resulted from pollution. In the aquatic food chain, plankton appear high up. The green house gases contribute majorly in the depletion of the ozone layer. The sun's rays are absorbed by the ozone in the stratosphere and thus do not reach the Earth. There is very little of this gas in the atmosphere. In early seventies, supersonic transport was the chief cause of NOx radical output into the stratosphere. What are Greenhouse gasses? Prohibit the use of harmful nitrous oxide. These are categorized as ozone-depleting substances ODS. This double trouble, on one hand the ozone layer is depleting which will cause severe health problems to the human beings and on the other the bad ozone present in the troposphere is constantly increasing. The ozone layer shields the entire Earth from some of the harmful ultraviolet rays that come from the sun. Because Antarctica is constantly surrounded by a polar vortex, radical halogens are not able to be diluted over the entire globe.
Other gases include Methane, Ozone, and Nitrous oxide etc. This is the expected effect of increased greenhouse gases, which contain the Sun's energy heat in the lower atmosphere troposphere.
Thesis ozone layer depletion
Promote vehicles that use hybrid engine or electro-zero emission engine. Image Courtesy : cdn4. Rush Limbaugh argues that humans are safe, because volcanic chlorine has been working on the ozone layer longer than man-made chlorine, and yet we're still here. This layer of gas is slowly diminishing each day, and causes a great concern to our safety. NOx, CF Promote eco-friendly vehicle. It has a pleasant concentration at about 2 ppm or less, but higher concentration is irritating. It is a molecule made up of three oxygen atoms, which are very similar to the molecule we are familiar with O2 , the molecule needed for human respiration.
The ozone layer is instrumental in protecting the animals as well as the human beings and its depletion has been constantly on the rise which is not good news for the human beings.
NOx destroys ozone, heating up the stratosphere by absorbing ultraviolet radiation.
