Pages 4
Ozone depletion is a man made phenomena which industries release CFC (chlorofluorocarbons), rising up to the upper atmosphere exposing to high energy UV radiation from the Sun. Even though that CFC has low reactivity, flammability and toxicity, it remains inert in the troposphere as they disseminate among the stratosphere whereas the UV rays strikes the CFCs molecules and releases chlorine. The chemical reacts with ozone (O3/oxygen), a natural combination of O2 (oxygen) molecules and free oxygen atoms (O1) splitted by O2, by striking an ozone (O3) it leaves chlorine monoxide and an oxygen molecule, resulting in a loss of oxygen.

This situation brings unfavorable results and consequences on living beings. It may cause human skin cancer and cataracts, affecting a plant’s formation, developmental process and nutrients absorbing; also implicating on their predators. Like plants, it is also a threat to the growth of marine and water ecosystems, and it affects the natural balance of gases, which, considered as biogeochemical cycles. The ozone layer can only be recovered by its own as we prevent releasing chlorine, such as replacing chlorofluorocarbon with chemicals with alike properties. This

Theoretically, if the natural production and its depletion can be balanced it would not cause trouble, which unfortunately, might be an impossible objective. Ozone is produced by the sun from immense energy, twice the energy used in America, a natural gas that can only be replenished on its own by time. In reality, the only way to stop destroying the ozone is by removing the excess chlorine out of the stratosphere, replacing alternatives with similar properties as CFC such as hydrocarbons with low reactivity and don’t produce free radical while exposed to the UV light, or fluorocarbons that can withstand the UV

...include methane (CH4) and nitrogen oxide (N2O) are emitted into the atmosphere during these industrial processes hence there is the depletion of the ozone layer resulting in the so called ozone hole. Thus the essay below would highlight more on human’s impact on the atmosphere and later effects of the ozone hole which in turn affect them. Albarca J.F (2000) notes that an ozone layer is a belt of ozone gases which is located at about 15 to 50km above the earth surface. This layer blocks harmful ultraviolet (gamma and alpha rays) part of the solar radiation from reaching the earth surface which will in future cause nonmelanoma skin cancer. Ozone depleting substances like chlorofluorocarbons thin this ozone layer resulting in a large area having half or less ozone than normal to appear hence the term ozone hole. Handwerk (2000) elaborate that the ozone is created naturally when oxygen molecules high in the atmosphere get broken by sunlight into two free oxygen atoms. A free atom can then bond with an unbroken oxygen atom and ozone is born. Ozone depletion happens when an ultraviolet light breaks the molecular bond in the CFCs and free atom get released. Chlorine then destroys ozone molecules by “stealing” their oxygen atom, hence the term ozone depletion. With increased reaction of this matter it will result in the so called ozone hole. Thus in my own view ozone layer is located in the stratosphere, helping in the protection of harmful ultraviolet rays from reaching the earth...

...In primary School, we would define the atmosphere as a“ blanket covering the Earth” but in general it is defined as a layer of gases that surrounds the earth , I like to define it as the source of life ,that is to say there would not be life without the atmosphere . The atmosphere insulates the Earth from extreme temperatures; it keeps heat inside the atmosphere and it also blocks the Earth from much of the Sun's incoming ultraviolet radiation (NASA 1999). The Earth’s atmosphere is divided into four different layers , namely , the Troposphere , Stratosphere , Mesosphere and the Thermosphere, In this essay , I am going to explain , with the aid of a diagram the layered structure of the atmosphere, the different temperatures that occur and also the different processes that take place in all the layers. layered structure of atmosphere As you can see in this picture above, this is how the layers are positioned in the atmosphere, it starts with the Troposphere which is the bottom layer and the one closest to the Earth ,it is the most important layer because all life takes place here, the important gases which are essential for living are found only here , it has a height of 12km, almost all weather occurs in this layer, the air is warmer at bottom of the troposphere and as you go up it gets cooler until eventually it reaches a point of dryness because altitude varies with latitude All the different layers have boundaries that separate them, in the troposphere it is......

Air Pollution

...This essay is about Air Pollution, Sources of Air Pollution and Effects of Air Pollution Air pollution is the presence of abnormal concentration and abnormal constituents in air. We know that Fresh air is needed for a healthy life. That is why people go out for morning walks so that they can breathe as much fresh air as possible. But the quality of the air has been deteriorating in urban areas. It is being polluted by smoke, harmful gasses, dust articles and other matters. The burning of petrol and diesel in running vehicles emits carbon monoxide, sulphur dioxide and unburnt hydrocarbon particles. These pollutants are released in the air breathe. They are very harmful for out health. The burning of various fuels in factories and power plants emit carbon monoxide carbon dioxide and other poisonous gases that are left off in the atmosphere. Yet without burning fuel, the production of goods in industries is not possible. So the growth of industrial production is at the cost of polluting air. Various chemical industries such as those manufacturing acids, plastics, dyes and paint, paper, pesticides, petrochemical emit hazardous fumes and gases such as sulphur dioxide, nitrogen oxides, hydrocarbons and fluorocarbons. Industrial dust also causes air pollution. Dust coming out from the cement kilns, lime kilns, stone crushing and asbestos factories are the main causes of breathing problems and lung diseases in our country. Smoking of cigarettes and bedis is very injurious to......

The Air We Breathe

...Xx J. B. English 101 March 20, 2010 “Is Air Pollution a Belief?” Winter-Koger’s essay “What on Earth Are We Doing?” discusses many environmental problems, e.g.: ozone depletion, global warming, overpopulation, deforestation, air and water pollution, topsoil loss, and coral reef destruction. While it is difficult to isolate one problem to discuss, as they are all equally, important environmental problems; I have decided to research the effects of outdoor air pollution. I am interested particularly in whether the United States has made any positive changes for cleaner air, or added to the negative impacts on two of six different types of air pollution-ozone(smog) and particle pollution (particulate matter) since Winter-Koger’s essay (2004). Air pollution is one of the many environmental problems faced each day around the world. Man has always been a solid contributor to environmental pollution, a problem passed on from generation to generation. Air pollution is not a belief that one has; but a real problem that absolutely does exist. Many people have dedicated their lives to finding a solution to the detrimental effects of air pollution. And many people, unknowingly, and some ignorantly, have dedicated their lives to contributing to air pollution. To better understand the effects of air pollution, one must first understand the definition of air pollution and how it is caused. You may disagree and feel you know the definition of air pollution; but ask the person......

Our efforts and determined contribution to reduce global warming and spare the ecosystem to recover thereby cautiously working restore the balance of nature is very urgent. Pollution of the atmosphere has to be checked and anything related to the release of the greenhouse gases should be monitored. Deforestation should be stopped as it causes the concentration of carbon at a greater extent. It has been said that it takes roughly 19 trees to make one ton of paper and that the usage of one ton of recycled paper will save approximately 17 trees. The burning of wood should be reduced to a greater extent as it releases oxidizable carbon to the atmosphere whose presence in greater amount causes the elevation of temperature.

Deforestation

...Research Essay Deforestation Leads to Serious Problems In the 21st century, the world is advancing to new heights in the field of technology. Human beings have made every facility for their better life. But human beings did not care about nature. Deforestation is the result of unawareness of human beings about nature. Deforestation has direct relationship with success of human beings. Thousand years ago, more than 80% of total land area was covered with forests. In present days, less than 12% of total land area is covered with forests (Hermy 362). Is cutting of trees beneficial for society? Does it lead to serious problems? Some people argue that deforestation is deforestation is necessary for success of many government projects and humanity. However, I would argue that the environment, wild life and human life are negatively affected by deforestation. It has large number of demerits. It has degraded environment by global warming and acid rain in different areas of world. Moreover, deforestation destroys the natural home of wild animals. Wild animals have no homes for living in most of parts of the world. Deforestation disturbs human life by depletion of ozone layer of the earth, increase in concentration of carbon dioxide in environment and reduction in the number of trees, which are used in the production of many medicines. These problems had not fixed. These are increasing day by day with the rate of cutting trees. To illustrate, deforestation has......

Global Warming

...Global warming is a severe problem facing the world today. Based on the 2007 Fourth Assessment Report (AR4 2007) by the Intergovernmental Panel on Climate Change (IPCC), as Earth’s climate began to change due to the rise of global temperature, there will be an increased tendency for drought, melting of ice sheets in Greenland or Antarctica and this will pose a major threat to human existence. The greenhouse effect is much to be blamed for global warming as carbon dioxide accumulated at the atmosphere will prevent most of the outgoing infrared radiation at the atmosphere from escaping into outer space. The main source of carbon dioxide emission is the burning of fossil fuels to generate energy in order to meet our daily requirements. Although the dependable energy supply by fossil fuel is essential in our every day life, because of its adverse effect is why the government should implement policies to encourage the use of renewable energy resources to conserve the environment. Fossil fuels like coal, petroleum, uranium, natural gases are non-renewable energy sources, which mean these resources cannot be re-made or regenerated. In contrast to that, renewable energy resources like hydroelectric energy, solar energy, wind energy, and geothermal energy do not deplete, or it will take a substantially long time to deplete them as it can be replenished by nature. Statistics has shown that there is an increase in the investment of renewable energy over the pass few years, in 2007......

In the ancient times, the population was manageable, and people could use the available resources for the family needs to sustain them. In the modern world and with the changes in technology, there has been difficulty because people are experiencing high living standards and more demand of resources. This study features on ways that a business can use to deliver products that are essential to the population, which rapidly grows in the world, and the adaption methods to both social and demographic changes. It will also outstanding on the technological impact to the business operations and reliability in the ensuring that they meet people’s needs. The development in technology has led to increase in the number of people in the world, leading to faster depletion of resources. This, therefore, necessitates improvement in company production and improved services so that they can be able to meet the increased requirements of the population. These companies also need to adapt to both social and demographic changes to enable them work efficiently and effectively (Wothington & Britton, 2009, 12).

Technology

...Technology has become so helpful to our lives in so many ways. Technology is convenient and efficient. It aids us to live life more conveniently by allowing us to do more in less effort. It, then, becomes rather difficult to undermine the importance in which technology plays within our lives. Many people have benefited from the invention of technology and would most often find it complicated to do without. Year after year, technologies become reinvented through new ideas and the betterment of equipment and tools. Thus, if an old technology does not suffice, a new one will easily come in favour shortly after.  Because of the rather innovative current forms of technology, new and advanced technologies are forming at an impeccable pace. The expressions, “I would die without Internet” or “I could not ever live without my cell phone” imply that life would be hard to live from the lack of such technologies. However, such expressions become rather ironic because life is already in harm’s way due to technology itself. The relationship between technology within society and environmental grounds are problematic. Technology serves as an efficient function to our lives yet can become detrimental to our health which is demonstrated through Ronald Wright’s theory of the progress trap and theories of environmental degradation (Cameron, par. 5). However, the repair and reversal of a damaged environment depends largely on technology through means for better water, cleaner air and conserving......

Critically Evaluate the Factors Influencing the Global Heat Budget

...CRITICALLY EVALUATE THE FACTORS INFLUENCING THE GLOBAL HEAT BUDGET - 40 MARKS The global heat budget is the balance between incoming insolation, and outgoing radiation from Earth. There are many factors that influence this heat budget, some of which are more important than others. In this essay I am going to describe and explain each factor involved. Insolation is the incoming energy from the sun in shortwave ultraviolet (UV) radiation. The distribution of insolation over the Earth’s surface is complicated; however there are patterns to be seen. Insolation has numerous aspects to it that each affects it in turn, which are divided into three categories of long term, short term and local. Quite possibly the most important aspect is latitude, a long term factor. The effect of latitude on the heat budget can be seen all over the globe, but the most striking examples are that the annual amount of insolation in the Arctic region, located 66° north of the equator, is 75 W/m2 however it is 275 W/m2 in Egypt, located 26° north of the equator. Latitude holds such a large effect on insolation because a variation in latitude means variations in the altitude of the sun. Altitude of the sun affects insolation because as the angle of the sun in the sky decreases and becomes more oblique, the land area to be heated up by the rays and the depth of atmosphere they must travel through increase. Therefore the amount of insolation lost through absorption, scattering and reflection increases....
