Air Pollution and Climatic Changes Essay Example for Free

Air Pollution and Climatic Changes Essay Air pollution is actually the addition of any harmful substances to the atmosphere, which causes the damaging of the environment, human health and the quality of life. Air pollution has been a serious problem throughout the history. This can have series effect on the health of human beings. Every day, the average person inhales about 20,000 liters of air. Every time when we breathe in we inhale dangerous substances. These dangerous substances can be in the form of gases or particles. Sources of Air pollution: †¢Natural source †¢Artificial source Natural sources: Natural air pollution does not occur in abundance and also possesses little threat to health of the peoples and ecosystem. Volcanic eruptions, Forest fires, Biological decay of organic matters are some of the natural causes of air pollution. Artificial sources: The man made reasons for air pollution are vehicular emission, burning of waste products, thermal power plants, industries and refineries. Vehicular emissions are responsible for 70% of the country’s air pollution. * Bharat stage 1 to 4 emission norms are emission standards that focus on regulating pollutants released by automobiles. Most sulphur dioxide comes from power plants that use coal as their fuel. Automobiles produce about half of the nitrogen oxide. When wood, household garbage, plastic, or leaves are burned, they produce smoke and release toxic gases. The smoke contains vapors and solid compounds suspended in the air called particulate matter. The particulate matter and toxic gases released during burning can be very irritating to people’s health. People who are exposed to these air pollutants can experience eye and nose irritation, breathing difficulty, coughing, and headaches. People with heart disease, asthma, emphysema, or other respiratory diseases are e specially sensitive to air pollutants Major air pollutants: †¢Sulphur oxide †¢Nitrogen oxide †¢Carbonmono oxide †¢Decomposition of organic matters. * India emits the fifth most carbon of any country in the world. * The Bhopal gas tragedy is one of the world’s worst industrial disasters that killed almost 8,000 people in December 1984. Air pollution can adversely affect human health not only by direct inhalation but indirectly by other routes through water, food and skin infections. Health hazards due to air pollution: †¢Cardio vascular diseases †¢Asthma †¢Bronchitis †¢Allergies †¢Lung and heart diseases. Consequences of Air pollution: 1.Ozone layer depletion 2.Global warming ( Greenhouse effect) 3.Acid Rain 4.Smog Ozone layer depletion The atmosphere contains a thin layer of ozone about 24 to 40 Km above earth’s surface which protects us from harmful ultraviolet rays of the sun. The release of chemicals such as CFC widely used in refrigerators has damaged the ozone layers. Ozone monitoring stations in Antarctica have already detected average loss of 30% to 40% of total ozone over the region. Each one percent loss of ozone is to cause an increase of about 2% in UV Radiation. This will reduce the immunity of the body and cause eye cataracts and skin cancer. For the protection of ozone layer, Montreal protocol and Vienna meet of 30 nations world wide agreed to reduce the use of CFCs. Global warming Global warming is caused by increase of greenhouse gases such as carbon-di-oxide, methane, water vapour, CFCs which are responsible for the heat retention ability of the atmosphere. The rapid increase in average temperature of earth will cause major changes in weather pattern all over the world. Rise in global temperature, will also result in the melting of polar ice caps glaciers. This in turn will raise the sea level. Land use changes will occur in coastal areas due to sea level rise. It will cause damage to coastal structures, post facilities and water management systems. Global warming also affects the agricultural patterns. Intense tropical cyclone activity has increased in the North Atlantic since about 1970 Heat waves have become more frequent over most land areas. More intense and longer droughts have been observed over wider areas since the 1970s, particularly in the tropics and subtropics If ocean temperature increases, growth of coral reefs will be affected. The corals control the proportion of carbon dioxide in water by turning them in to limestone shell. Moreover, coral reefs grow in temperature just above 10 degree Celsius. Other ecosystems such as forests and desert will also be harmed. Loss of bio-diversity and extinction of rare species will occur. Acid Rain: Acid rain was first discovered in 1852. This is one of the most important environmental problems, caused by indivisible gas given out by automobiles or coal burning by power plants. The gases that cause the acid rain are sulphur- di-oxide and nitrogen oxides. Fire and bacterial decomposition are the natural causes which increases nitrogen oxide in air. These pollutants combine with water vapour in the presence of sunlight and oxygen and forms dilute sulphuric and nitric acids. When these mixture precipitates from the atmosphere, it is called acid rain. Acid rain falls down to the earth in all forms of precipitation. Acidity in the rain can harm and even destroy both natural ecosystems and man-made products. Acid rains, when falling on oceans, reach the coral reefs. This has killed more than 70% of corals in Lakshadweep and Andaman islands. They also change the acidity level of the soil by leaching crucial nutrients. Thus it affects forest vegetation. The most basic microscopic organisms such as plankton may not be able to survive. So the sea animals depending on planktons will die and the food chain will be affected. Smog: The word smog is a combination of the words smoke and fog. Smog causes a smoky dark atmosphere, especially over cities, it decreases visibility, and creates gaze throughout the area. Smog is caused by many factors, major producers of smog include automobiles, fires, waste treatment, industries, etc. The articulates present in smog include carbon monoxide, dirt, dust. The smog effect is created when sunlight, hydrocarbons, nitrogen oxide are mixed together smog creates harmful health hazards like lung failure and pneumonia. Smog is not only a city problem. As smog level increases, wind carry smog away from urban areas and harm other areas too. Agriculture is also affected by smog.

The around The World Party At College :: essays research papers

The "Around The World" Party at College As I approached the party I could hear the blasting music all the way from the street. When I reached the back of the house to enter I could distinguish the song that was playing; it was â€Å"It's good to be King† by Tom Petty. After waiting in a line to enter I was finally in the loud, crowded house. Upon my arrival the host of the party informed me that there were no cups left, and that I would have to look for one. So I handed him my money as I was shoved into the next room by other arriving guest, eager to enter. Every person there was present for their own personal reasons. Whether these reason be social or simply for entertainment no one could tell. The only thing we all had in common was our goal to consume alcohol. As soon as I walked in the room I immediately could see and smell the smoke that was lingering in the air around the house. I was handed a cup by a friend. Looking into it to see if it had been used, we both shrugged and turned towards the basement. As I pushed my way through the crowd to look for the keg I immediately knew it was in the corner because of the crowd surrounding it. Once I reached the keg, I found myself waiting once again for my beer. The person who was filling up the cups was not filling them first come first serve. He would fill the cups of his friends first, then the girls, and then if he had to fill up his own cup he would. While doing this he was talking his friend whose job it was to pump the keg when needed. People were sticking their cups in front of the tap as if they were fighting for food, and they hadn't eaten for days. There must of have been twenty people all forcing their cups in the general area of the tap. Once I had my beverage, I decided to go visit the rooms to see what kind of alcohol was being served. This party was an â€Å"around the world party† which meant that every room had a different theme and appropriate drinks to the theme could be found there. My first stop was Jamaica. When I entered the room the first thing I saw was this guy dressed up like a native Jamaican, appropriate to the theme of the room. He had on a bright tie- dyed shirt with a dread locked wig.

Business Research Methods & Tools Essay

2.Suppose you were preparing two-way tables of percentages for the following pairs of variables. How would you run the percentages? When two-way tables are being done this is usually because one of the variables is thought to be the cause, affect the cause, or predict the response of the other variable. This is called the (IV) independent variable (Cooper & Schindler, 2011 p.446). aAge and consumption of breakfast cereal. I would categorize age as the IV and percentages should be computed in the direction of this variable to show that age has some effect on the consumption of breakfast cereal. bFamily income and confidence about the family’s future. I think with this scenario either one could be used as the IV to determine whether higher income families compared to lower income families have more or less confidence on their family’s future. cMarital status and sports participation. I would use marital status as the IV and compute percentages in the direction of that variable to determine the effects that marriage has on sports participation. dCrime rate and unemployment rate I would use the unemployment rate as the IV and compute the percentages in this direction to show that unemployment rates have an effect on crime rate. Inquiring Minds Want to Know Case study 1.Build the management-research question hierarchy. Management Dilemma: Will Penton Media encounter lower advertising revenue if alternative methods of inquiry stimulation went untracked due to the usage decline of reader service cards? Management Question: Are business publication advertisements generating fewer leads than in the past? Research Questions: Do we continue to include reader service cards in the magazines as a value-enhancing service to the readers as well as the advertisers? What alternative methods using information technology can be implemented to enhance adverting revenues as reader service card usage declines? Investigative Questions: What are the percentages of subscribers using reader service cards in the present compared to the past two years? If there is a decline in usage, what are the alternatives the customers are using? Can we implement strategies to streamline those alternatives in information technology to sustain and enhance our advertising revenue? Management Questions: Will Penton Media experience a decline in profits due to alternative methods in information technology of customer inquiry stimulation from advertisements? Management Decision: Discontinue the use of reader service cards and it will be replaced with alternative methods by use of emerging information technology, which will integrate the customer with the advertiser on a real-time, customizable basis . 2. What ethical issues are relevant to this study? The largest issue relevant to this study was the issue of informed consent. During this study there is no mention that the participants of the study were fully informed of the details. I also believe that there was some researcher bias because out of the 676 buyers that responded only 40 respondents were followed up with to get more knowledge of their behavior and attitudes after data had been analyzed. I don’t think 40 people out of 676 would give accurate results of buyers attitudes and behaviors. One final ethical issue is the right to privacy (confidentiality). The cover letter in the survey indicates, â€Å"All individual responses will remain completely confidential†; however, it is Penton who has the responsibility of maintaining the confidentiality as it collects data from customers that can be most likely traceable to the survey participant based on the market and information data provided at the end of the survey. 3. Describe the sampling plan. Analyze its strengths and weaknesses. The sampling plan used is this survey was the stratified disproportionate random sample. This sampling plan was used because the researcher was looking to reach a specific subgroup within the population, and focused on disproportionate because there are different sampling fractions for each stratum. For example, out of 710 questionnaires received 676 were used and out of that only 40 were chosen for another sample. The strength of this sampling plan is that there is greater precision but the weakness is the difficulty to identify what the appropriate strata is for the study (Cooper & Schindler, 2011). 4. Describe the research design. Analyze its strengths and weaknesses. Research Design is the blueprint for the collection, measurement, and analysis of data (Cooper & Schindler, 2011). The research design consisted of a multistage communication study. In the communication study the researcher questions the subjects an d collects their responses by personal or impersonal means (Cooper & Schindler, 2011). The collected data resulted in a reader-targeted mail questionnaire by phone, then by mail questionnaire to a select 300 subscribers before finalizing the questionnaire to 4,000 managers, executives, engineers, and purchasing agents. The technique used in the questionnaire was qualitative, by asking specific questions on methods of contact between consumer and advertiser. Secondary research was used when 12 magazines were used to compare the inquiry response options that were/are offered. All of these designs can help to acquire data more cost efficiently than other designs and have the ability to reach more people. However, the data may not be as accurate as with other methods. For instance, the research from the magazines may not be accurate because Penton was relying on the fact that the information from the magazines was accurate and had been retrieved correctly. 6. Critique the survey used for the study. First, the survey used was segmented to purchasers of organizations instead of a sample that represented the entire publication population. The researchers noted the margin of error was +- 4%; however, a balanced sample of the population would have produced results that could be much different than the segmented sample population. If key managerial decisions are to be made based on this questionnaire, you should have the entire population represented. In this case, just because someone is not a purchase manager, Penton is ignoring the other subscribers who may also use the reader service card service as a consumer or through their own personal business. Besides the fact it excluded non-purchase approvers from the sample, the survey is well designed. The questions are clear, concise, and accomplish the goal of how users interact with advertisers on potential suppliers, products, and services 7. Assume you are compiling your research report. How would you present the statistical information within this case to the IndustryWeek decision maker, the manager who must decide whether or not to continue to publish reader service cards? I would present this information by developing bar graphs that show the usage frequency by years. The bar graphs will be effective because they can easily show the growth or decline of use throughout the years. 8. Assume you are compiling your research report. What are the limitations of this study? The research limitations are due to excluding respondents who are not purchase decision makers. The sample of the subscriber population was not a representation of the entire population but only of subscribers with purchasing ability. This will distort the results of the survey and could impact the decision on whether to continue or discontinue the reader service cards based on the opinions of one segment of the population 9. Assume you are the decision maker for IndustryWeek . Given the declining value of the reader response card to subscribers, originally designed as a value-enhancing service to IW readers and advertisers alike, what further research might be suggested by the findings of this study? Or do you have sufficient information to stop the use of reader response cards in IndustryWeek ? I think that even though the research was limited to a small segment of the entire population, I would still make the managerial decision to end the use of reader cards due to the declining usage and with the dramatic increases in alternative means by email, internet, and facsimile communication. I think it would be a better idea to look into other options to replace the reader cards.

Thomas Hobbes and John Locke were two of the most influential philosophical andpolitical thinkers of the seventeenth-century. Hobbes and Locke had different ideas on how torun a country and had different views on the natural state of human beings. Hobbes believed thata commonwealth ruled by a sovereign was the only way to run a successful government, while Locke was a defender of moderate liberty and toleration. Don’t waste time! Our writers will create an original "Philosophy Of John Locke and Thomas Hobbes" essay for you Create order Both of these have been utilizedthroughout history, sometimes to great effect and other times to the downfall of a nation. Hobbesand Locke were both influenced by the likes of Renà © Descartes and Galileo, and bothincorporated other peoples ideas to formulate their own opinions and thoughts. To this day, Thomas Hobbes and John Locke have been influential in shaping the way the world thinks aboutphilosophy and politics.Thomas Hobbes was an urbane and much-traveled man who supported the scientificmovement. His first published work was the first English translation of Thucydides History ofthe Peloponnesian War. Hobbes viewed humans as self-centered creatures who lacked a master, which derived from Thucydides historical analysis. According to Hobbes, human beings areinclined to a perpetual and restless desire for power. He thought that since all people want andpossess a natural right to everything, this equality breeds enmity, competition, diffidence, andperpetual quarreling. His influential work, Leviathan, published in 1651, provided philosophicaljustification for a strong central political authority. To Hobbes, the original human state is one ofnatural, inevitable conflict in which safety does not exist. Hobbes believed that life in this stateof war was solitary, poor, nasty, brutish, and short and that the only way humans could escapethis was to enter a political contract. This contract was to agree to live in a society that is tightly ruled by a recognized sovereign. The agreement obliged every person to agree to set asidepersonal rights to all things and to live by a version of the golden rule, Do not that to anotherwhich you would not have done to yourself. Additionally, this contract allowed the use of forceby the sovereign to compel compliance. Hobbes did not care whether this was a monarchy or alegislative body, but once one was chosen, it could not be appealed. Hobbes was met with muchcriticism, but his political views sparked conversations about government that had not been hadbefore this time period. John Locke was a highly intellectual person who was well-read in all the majorseventeenth-century natural philosophers. He was a defender of the rights of the people againstrulers who thought their power absolute and had Puritan sympathies. In 1690, he published twotreatises that detailed his views on government. His First Treatise of Government rejected arguments for absolute government that based political authority on the patriarchal model. HisSecond Treatise of Government presented an argument for a government that must be bothresponsible for and responsive to the concerns of the governed. Unlike Hobbes, Locke sawhumans in their natural state as creatures of reason and goodwill. Locke believed that humansshould have the natural rights of life, liberty, and property in an unregulated manner. He believedthat humans possess a capacity for living peacefully before they enter a political contract. Lockesaid that the state of human nature is a condition of competition and modest conflict that requiresa political authority to sort out problems rather than impose authority. His government isobviously one of limited authority, and the people reserve the right to replace their politicalauthority if the need arises. Although, Locke did not defend religious toleration among all Christians. Government-imposed religious uniformity could not achieve real religious ends because Locke thought that religious truth must be freely given. Nonetheless, he did not extendtoleration to Roman Catholics, who he believed gave allegiance to a foreign prince (the pope), non-Christians, or atheists in his Letter Concerning Toleration (1689). John Locke established afoundation for the future extension of toleration, religious liberty, and the separation of churchand state.Hobbes and Locke differ on almost every single view and topic related to politics duringthis time. However they have one major similarity: they both believed that all humans arenaturally equal. Religious beliefs aside, both Hobbes and Locke truly thought that everyone intheir natural form was equal. Even with that similarity, Hobbes and Locke were perceived asvastly different. Locke was met with universal praise because his views pleased the people of Europe (despite the religious intolerance), and his political ideals were very similar to manyother countries during this time period. Hobbes, on the other hand, was criticized severely byMonarchists and Republicans alike. Monarchists objected to his willingness to assign sovereignauthority to a legislature. Republicans rejected his willingness to accept a monarc hical authority.Many Christians criticized his materialist arguments for an absolute political authority. Other Christian writers attacked his refusal to recognize the authority of either God or the church asequal or above the sovereign ruler. This meant that Hobbes had little immediate impact, howeverhis ideas have influenced philosophical literature from the late seventeenth-century to this day.Thomas Hobbes and John Locke have been monumental in shaping modern politics sincethe seventeenth-century, and their impact can still be felt today. They were vastly different interms of views and beliefs, but both had the same goal in the end: to create a better government.Whether or not they succeeded remains to be seen, but they put the world on the right track.
