Automobile? The Main Source of Pollution? Essay
Innovation and creativity, these are the very benchmarks that pave the way in producing new technology that governs the very lives of our future. But the question is, is it doing more harm than good to society? To verify the nature and essence of this query, I will be inquiring and delving into the world of automobiles and motorcycles. On one hand, I balance the modern wonders that craft the very definitions of convenience and comfort. While on the other, I hold the unfathomable realities that draw the line between useful and harmful. Therefore, let it be stated that I have come to an understanding that both automobiles and motorcycles pose a substantial threat the world is constantly ignoring.            In probing this discussion, I will begin by first illustrating the statistics on ownership of automobiles and motorcycles made in the United States. Then, I shall be focusing on the comparison between the subjects and issues that society deals with regard to automobiles and motorcycles by citing some examples in Southeast Asia. Lastly, I will emphasize the known facts and matters that give impact on the current view of automobiles in the society.            To start with, it is acknowledged that present ownership of the automobiles is increasing day by day. According to the US Bureau of Transit Statistics for 2004 there are a total of 243,023,485 registered passenger vehicles in the U.S. of which 136,430,651 (56.13%) are classified as cars. While 91,845,327 (37.79%) are classified under 2 axles and 4 tire vehicles, presumably SUV’s and pick-up trucks. Yet another 6,161,028 (2.53%) are classified as vehicles with 2 axles and 6 tires and 2,010,335 (0.82%) are classified as trucks in combination. In addition to that, there are approximately 5,780,870 motorcycles in the U.S. in 2004, which accounts for 2.37% of all registered passenger vehicles. With the increasing number of automobiles yearly, there is a plan to see an effective way of reducing the emissions from cars through hybrids, diesel and other form of technology.            Recent studies show that automobile emissions are not as bad as motorcycles emissions. Usually, motorcycles are not the major form of transportations in developed countries. Astonishingly, the American Chemical Society reports that motorcycles collectively emit 16 times more hydrocarbons, three times more carbon monoxide and a â€Å"disproportionately high†amount of other air pollutants compared to passenger cars (Science Daily, 2008). The study, by the Swiss Federal Laboratories for Materials Testing and Research, has found both two- and four-cycle motorcycle engines emitted significantly more of these pollutants than automobile engines. Given this data, we can now see the ineffectiveness of motorcycles. Given the sitting capacity of a car compared to a motorcycle, a car is able to hold twice as much sitting capacity compared to motorcycles. In developing countries such as Indonesia, the number of motorcycles is overwhelming compared to the number of automobiles. Being born in Surabaya, Indonesia, I have witnessed some of the worst air pollution that I have ever encountered. It has been so bad to an extent that I can see dust on my front porch every ten minutes upon mopping it clean            Although, there have been seen steps taken to reduce the emissions in automobiles, regulations has been a bit late for motorcycles. This does not take into account the other subjects related to pollution such as air contamination, water contamination, soil contamination, and solid waste mishandling ( L. Gari, 475 – 488).Unlike automobile emissions that have been regulated only after 1970s, the motorcycle emissions have only been regulated only after 1999. This technological advancement has made motorcycles less harmful to the environment. Thus, future bikes may have emissions from new motorcycles at a same level of emissions as cars. For example, the 1000cc Suzuki V-Strom produced in 2002, equipped with a regulated catalyzer, oxygen sensor and fuel injection, complies with 2003 emissions limits and is very close to the 2006 ones (Motorcycle Emission, 2008). It is also said that they have reduced 60% of the carbon monoxide and hydrocarbons emissions of new four-stroke bikes produced from the 1st April 2003 and reinforcing it on 1st January 2006. This will in turn apply a further 50% reduction compared to the 2003 limits. Two-stroke engines will see their emissions output reduce by 30% for carbon oxide and 70% for hydrocarbons. Hopefully, motorcycles will have low level of oxides of nitrogen and limits will remain the same for 2003 giving the time for the industry to achieve more drastic nitrogen oxide measures for 2006. With this at hand, Indonesia air pollution would be drastically reduced.            Automobiles and motorcycles affect our environment and push them into critical conditions. There are even unusual emissions that are produced in the atmosphere (Beychok, 29 – 36). Pollutants from automobiles are the major causes for green house effects and other environmental pollutions. Although Bangkok is praised with their three-wheeled vehicles whose name comes from the sputtering sound produced by their horribly polluting two-stroke engines, â€Å"tuk-tuks†look like beat-up golf carts with roofs and backseats and function as inner-city taxis (Hertsgaard, 1999). Unfortunately, â€Å"tuk-tuks†and motorbikes, in terms of mobility, are undercut by their abnormal tailpipe exhaust that burn a fuel that is part gasoline, part benzene. Benzene of course causes cancer and each flick of a driver’s wrist sends thick puffs of bluish-white smoke into the already soup like air (Hertsgaard, 1999). Though the presence of â€Å"tuk-tuks†created many jobs as a â€Å"tuk-tuk†driver for the people in Bangkok, it also cost them their health as prolong breathing of benzene causes cancer.            Nowadays, diesel cars are cleaner than the petrol cars. Modern technologies have been applied in order to reduce the level of emission from cars. For example, carbon dioxide emissions are directly proportional to fuel consumption, and as diesel cars use 30 to 40% less fuel and they emit 30 to 40% less carbon dioxide than petrol cars (Vasic and Weilenmann, 149 – 154).  On the other hand, natural gas and LPG cars are actually quite fuel inefficient, if otherwise cleaner burning, and so produce more CO2 than diesel. Diesel engines produce virtually no carbon monoxide.  Emissions of nitrous oxides can be effectively reduced in both petrol and diesel cars by use of exhaust gas recirculation (EGR).  EGR reduces the combustion temperature to below the point where nitrogen effectively burns. Hydrocarbon emissions are contained in petrol engine emissions much more than in diesel engine emissions.  Benzene is also present in the fumes which can be smelt when filling up with petrol at a service station; however this is not a problem with diesel.            Personally, I strongly feel that it is necessary for everyone to get a car since it has a viable use in the lives of ordinary men and women. Moreover, cars have been viewed as a twentieth-century technology (Hertsgaard, 1999). Since the invention of automobiles, more and more industries associated with it have begun to expand. This in turn provides enormous employment opportunities to the people. With that, countries such as Thailand, China and Bangkok have soon started to welcome foreign automobile industries to invest in order to boost their economic progress. One great example of this particular event is the success story of Thailand. Over the past two decades, Thailand’s per capita income in 1991 was U.S$ 1,570â€â€a stunning six fold increase over the 1971 figure of U.S$271 making Thailand an apparent economic success story (Hertsgaard, 1999). With a sudden massive economic growth in an automobile industry as have been seen, there comes a price that everyone has to pay.            In conclusion, not only automobile’s emissions is held scapegoat to many people around the world for global warming and the increase of greenhouse gases, certain factors such as the massive motorcycles emissions are also partly to blame. Both the automobile and motorcycles affect our environment and push them into critical conditions such as the green house effects and other environmental pollutions. Overall, I agree with Hertsgaard when he made a strong point that â€Å"proponents of the car like to point out, as the Mobil Corporation did in a 1995 advertisement in the New York Times, that the cars and skies in the United States are much cleaner now than they were a quarter of a century ago†(Hertsgaard, 1999). This statement he makes inspires the entire environmentalist out there that their efforts have not gone too waste. WORKS CITED ScienceDaily.Amounts of Air Pollutants.

Self-evaluation            Upon starting this essay, I experienced several setbacks and challenges. It took me a total of 3 days of researching and 2 days to complete the essay. The first thing which I did in this essay was the search for good source information for this research. This was hard as I have to be able to find data which preferably have a range of 10 years. Secondly, I read the Top Ten Tips on the transition and brilliant beginnings and I really can see myself being a better writer with it. The last and final step was for me to put all the information down and start writing followed by proofreading. For this research only managed to do a single draft and I did not get the help of any body except the tools of Microsoft words such as its thesaurus and dictionary. I believe that my strong and insightful data on the emission outputs of automobiles and motorcycles are the strengths of my essay. In addition to that I believe that my essay is weak because of proofreading problems. One of the primary problems that I have with this essay was that I have to retype everything again due to a computer problem. The essay was supposed to be done on my lap top. However, it crashed and I am unable to backup my data causing me to lose come information that can help me with this essay. One thing that I would do next time is definitely to start earlier and have a visit to Dr Lankford office to ask him on his views on my current ideas for the essay. I would definitely rewrite this essay for the second time in hope to have at least a B+/- for this course as it depended on this essay.
