The company uses these parts for reducing the cost for manufacturing the equipments. In this way, they gain more profit. However, it results in harming the environmental stability by depletion of the Ozone layer. Carbon emission by various tools and equipments used in manufacturing industries also contribute to the global rise in the temperature Jakob and Marschinski Carbon has dense gaseous particles that entrap the heat rays of the Sun in the atmosphere.
It results in increasing the average temperature of the earth. Hence, the global warming is induced in the atmosphere. All the economic activities of the world depend on the production of the energy and the main source of the energy is coal.
For production of energy the coal is burnt and it increases the amount of carbon in the atmosphere. The main ethical dilemmas because of Ozone layer depletion are affecting of exposure to the UV rays on the ecosystem and its components and diseases caused by it.
The ozone layer acts as a shielding layer for the earth and its ecosystem from the harmful ultra violet UV rays of the sun. These rays when come in direct contact with the skin of human or animal birds and fishes included or the body of the plants causes decaying of the part Calkins Hence, the part of the body or skin becomes dead and unusable. The increase in the temperature have resulted in unfavorable climate for production of crops and doing work.
The global warming has resulted in melting the polar caps and increasing the water level of the earth. The two principle issues of Ozone layer depletion and Global warming are radiation effects and melting of the polar caps. These are the radiation effects because of UV rays on humans. In plants, the ultraviolet rays affect the plants growth, reduction in the area of the leaf, diminishing the size of the stem and affecting the cell structure of the plants.
The effect of UV rays in plants can be seen at both molecular and cellular levels. The reproduction system and photosynthesis process of the plants are also affected by the harmful rays of the Sun.
Melting of the ice caps at the polar region is the major ethical issue faced due to the global warming. The ice caps at the Polar Regions are melting slowly that has resulted in increasing the water level by a considerable amount every year Hansen et al. It has been seen that the average temperature of the earth increases by 0.
It has already been observed that the Ice shelves of Larsen and Ayles have been broken up due to the global warming. The ozone layer depletion and global warming have severe affect on the economic activities of the earth.
The ozone layer depletion and global warming have affected the economy by destructing the infrastructure and property, decreasing the productivity, massive migration, increases in the cost of cropping, and security threats to the economic activities. Destructing the property and infrastructure- The ozone layer depletion and global warming has caused a number of hindrance factors for the economic growth like; floods, rise in the sea level, draught, wild fires, and storms.
These have damaged the infrastructure and property causing the decrease in the financial condition of the affected areas Nelson et al. Decreased productivity- The ozone layer depletion and global warming has resulted in decreasing the productivity of the activities. Due to severe hindrance like storms, heavy rains, and climatic change, the economical activities like agriculture, transportation, fisheries, tourism and energy production are halted occasionally. The health issues due to climatic change also hinder the productivity of the economic activity.
Massive migration- Due to the various climatic situations of the places, the people has been forced to migrate to some other places for seeking the favorable conditions Farber It causes decrease in the economic activities of the place. Increased coping cost- Due to these calamities of the ozone layer depletion and global warming, the damages in the society would require a considerable cost for coping with the situation Farber It would result in decreasing the financial stability of the place, hence, ceasing the economic activity of the place.
Security threats- The climatic conditions due to ozone layer depletion and global warming become unfavorable for secure living. It results in expenses for managing the security options to overcome the threats. The ozone layer depletion and global warming can be solved by following some steps;. Ozone layer depletion can be solved by reducing the use of CFC emitter products. Apart from it, if the bromine and chlorine gas in the atmosphere is reduced, the reaction can be controlled too.
The companies should use the equipments that checks and controls the CFC emission in the atmosphere. The Montreal protocol should be made active in all the companies that focus on the reduction of the CFC emission products. Global warming can be checked by decreasing the carbon emission in the atmosphere. Gaseous carbon entraps the solar radiation and causes the rise in temperature. So minimizing the carbon content in the atmosphere would decrease the effect of global warming Jang and Hart It can also be reduced by managing the forestry and agriculture.
Utilizing the concept of eco friendly and go green in all activities can result in controlling the hazards to environment. The global warming and ozone layer depletion can be managed and controlled by reducing the emission of CFC and other heat entrapping gases in the atmosphere.
Apart from these stopping the misuse of the resources, utilizing public transport mostly, using energy efficient and less CFC emitting equipments and making people aware of the affects of the ozone layer depletion and global warming and their solutions can be used individually for reducing the hazards of ozone layer depletion and global warming on the Earth.
Some technical terms were matched from the assignment. Ozone depletion and global warming: Case for the use of natural refrigerant—a review. This ozone-oxygen cycle, known as the Chapman cycle , is continuous so that a molecule of ozone only lasts, on average, about 8. The ozone layer, 12 to 19 miles above Earth, is the region of the atmosphere where the physical-chemical conditions are most favorable for the ozone-oxygen cycle.
When a molecule such as oxygen or ozone is dissociated, the molecular pieces fly apart at high velocity, instantly converting all the bond energy into kinetic energy of translation. Average kinetic energy of translation of all atoms and molecules making up a gas is, according to the kinetic theory of gases, directly proportional to the temperature of a gas.
Thus, high concentrations of ozone show regions of localized warming that were first observed to affect weather and climate by Gordon Dobson in the s. When ozone is depleted, less ultraviolet-B is absorbed within the ozone layer, cooling the ozone layer, as observed from to More ultraviolet-B is then observed to reach Earth, where it penetrates tens of yards into oceans and is thus absorbed very efficiently.
Increased ultraviolet-B also dissociates ground-level ozone pollution, warming air in industrial regions. Ozone depletion is greatest in polar regions during the winter, explaining why the greatest warming observed from to was of minimum temperatures in polar regions, a phenomenon known as polar amplification.
Scientists suddenly realized that ozone depletion was a much bigger problem than had been thought. Within two years, scientists and political leaders developed the Montreal Protocol on Substances that Deplete the Ozone Layer mandating cutbacks in CFC production beginning January By , increases of CFCs in the atmosphere stopped. By , increases in ozone depletion stopped.
By , increases in average global temperatures stopped. The ozone layer remains depleted, the ocean continues to warm, ice continues to melt, and sea-level continues to rise, but global temperatures did not change significantly from through They also had not changed much from to Thus, humans appear to have accidently caused the warming starting around by manufacturing large amounts of CFCs and to have accidently stopped the warming of air in while trying to limit ozone depletion.
Meanwhile, atmospheric concentrations of carbon dioxide rose linearly, but at ever-increasing rates, showing no direct relationship to the details of observed global warming. Dozens of peer-reviewed scientific papers by leading atmospheric scientists have tried to explain, based on greenhouse-warming theory, why global temperatures did not change much from through , a phenomenon dubbed the global warming hiatus.
While they suggest many interesting ideas, there has been little agreement. These types of lava flows, covering tens to millions of square miles , have been contemporaneous with periods of greatest global warming, ocean acidification, and mass extinctions throughout all of geologic time. For example, million years ago, the Siberian basalts covered an area of 2. Basalts emit prodigious amounts of chlorine and bromine that seem to cause ozone depletion, although the precise chemical path has yet to be deciphered.
In the s, many leading scientists were convinced that greenhouse gases were the cause of global warming, that Earth was in danger of overheating during the 21 st century as emissions of greenhouse gases increase, and that scientists must demonstrate consensus in order to convince political leaders to take the expensive steps necessary to reduce greenhouse-gas emissions.
The IPCC has involved thousands of climate scientists writing tens of thousands of pages of thoughtful science supporting greenhouse-warming theory. The IPCC never did question the widespread assumption, however, that greenhouse gases were the primary cause of global warming. In December , this effort reached fruition with the Paris Agreement where leaders of nearly all countries agreed to work together to reduce greenhouse-gas emissions.
Science, however, is not done by popular vote. Science is not done by consensus. Consensus is the stuff of politics; debate is the stuff of science. Science is never settled. As Michael Crichton put it at Caltech in What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus. There is no such thing as consensus science.
Human activity has affected the biosphere on Earth as the population has grown. Some troubling effects include changes to the ozone layer and global warming.
The ozone layer depletion and global warming have severe affect on the economic activities of the earth. The ozone layer depletion and global warming have affected the economy by destructing the infrastructure and property, decreasing the productivity, massive migration, increases in the cost of cropping, and security threats to the economic /5(14K).
Ozone Depletion and Global Warming How the video was a good example of a persuasive speech? The video was a good example of a persuasive essay because of its overall structure from attention-getter and visual aid to the conclusion and performance. global warming - Stratospheric ozone depletion - Since the s the loss of ozone (O3) from the stratosphere has led to a small amount of negative radiative forcing of the surface. This negative forcing represents a competition between two distinct effects caused by the fact that ozone absorbs solar radiation. In the first case, as ozone levels in the stratosphere are depleted, more solar.
