The car vs the industy
From Mod Mania
The vehicle, it can move us from A-B and to C if we wish. It sits neatly on manufacturing and engineering work benches alike, however there is a large problem with the motor vehicle, this is that it is slowly poisoning the earth with its toxic mix of exhaust fumes. This is fact and cannot be taken out of context easily for we all know it to be true, and like “smoking kills” cultural myth does not apply to factual truths. The toxic mix of carbon dioxide, nitrogen oxide and particle matter, the list goes on, has been slowly filling our air since the combustion engine was introduced in 1876 but I doubt that it would have even been taken into consideration that one day this piece of machinery will help tp ruin the world. If they had, perhaps they would have stuck to steam and electrically powered vehicles like that of the ones in 1789. But if someone was to take out of context what the greater, environmentally beneficial contributions the motor vehicle made to the earth then “they” would be creating a myth, which if not proven incorrect can end up being the truth, a factor which many forward in stories, spreading the myth further and further. The motor vehicle however has many cultural myths applied to it. These myths have been brought on by what I can only see to be the extent of the wits of those who have experienced what was taken out of context in the first place. The myths of the motor vehicle other that safety concerns seem to have no strings tying down the sales of the motor vehicle and the truth of the matter is that there are more truths that myths.The U.S. burns 10,000 gallons of gasoline a second, this is the truth and must not be taken out of context. The motor vehichle is absolutly ruing our earth? this is fauls and has been taken out of context.
Concerning the motor vehicle, the largest area for Myths are in the field of pollution and global warming. Perhaps the largest myth known to man is that “if we all just stop driving we can save the planet”. This is incorrect and impractical as this essay states. If we all stopped driving we would save 3tons of carbon in the air for each vehicle per anum. It would reduce the world’s intake of oil by 1/2 and we would produce ¼ less greenhouse emissions each year. This is a large amount sure but the underlining factor is that the Motor Vehicle only produces ¼ of the greenhouse emissions, factories, power plants, houses and methane producing creatures produce the rest. Although there is a combination of pollutants that affect the climate and ozone there is one in particular that is a main cause of global warming. Carbon dioxide alonh with other monoxides and dioxides found in the exhaust of motor vehicles are found to be a major factor in the buildup of pollutants in our air; these carcinogens make it hard for some of us to breath, increasing chance of an early death. The main cause of air pollution is the burning of fossil fuels, something which is carried out by factories, houses and vehicles alike with steel and iron fabrication equaling 2 to 4 percent of industrial emissions of Nitrogen oxide, Sulfur oxides, Volatile Organic Compounds and Total Particulate Matter. This is not much but it adds up when you consider the amount of industrial practices that take place. To attribute to these figures and just to give you an idea of the damage of a large manufacturing process, steel and iron fabrication equals approximately 28 percent of industrial Carbon monoxide emissions, and approximately 13 percent of industrial green house gas emissions . Air pollution is the third most serious health factor in the world and factories that burn coal are the leading provider of toxins that cause global warming, acid rain, smog, and general air toxins. Each year operating coal burning factories pump out 3,700,000 tons of carbon dioxide, 10,000 tons of sulfur dioxide which is the leading cause of acid rain and 500 tons of small airborne particles which can cause asthma and bronchitis aswell as 12,200 tons of nitrogen oxide which leads to formation of ozone (smog) which inflams lungs and burns through the tissue making people susceptible to respiratory illness. As alarming as thsese figure are 12,200 tons of nirogen oxide is equivalent to the same output admitted by ½ a million late model cars. But despite this looking bad for the motor vehicle it is important to remember that cars account for only ¼ of the greenhouse emissions, factories that burn hydrocarbons, your house and smaller factors like the mixing of asphalt and animal emissions. 720 tons of the carbon monoxide a toxic gas that affects the central nervous system and heart as well as being damaging to a fetus is released into the air each year is accountable by coal burning factories. Considering the world as a whole, the burning of fuel provides about 85% of all the energy used. In the United States 70% of electrical power is generated by burning fuel and more that ½ that fuel is coal. This is contrary to France where 78.4% of power is generated by Nuclear Power, 13.8% by hydroelectric and 7.8% is generated by burning fuel. It is estimated that air pollution causes 2,300 to 5,400 premature deaths a year in the state of the New Jersey alone, it is also the largest source of carcinogens contributing to the growing asthma, heart disease and bronchitis problems amongst children and seniors.
== Where does the smog and air pollutants come from? It’s a question that if you google search it you will find pages on “questions for kids” but it is not such a childish question. As already mentioned, smog and air pollutants are made up of a variety of different chemicals however transportation is a huge contributor to green house admissions and when you think that each car puts out 3 times its weight in CO2 (carbon dioxide) each year it is not hard to see that cars are coming second in the race to ruin the earth with factories coming first. The combustion of gasoline and other hydrocarbon fuels in automobiles, trucks, and jet airplanes product several primary pollutants: nitrogen oxides, gaseous hydrocarbons, and carbon monoxide as well as large quantities of particles, mainly lead. These pollutants when combined with sunlight form other classes of pollutants, for instance when you combine nitrogen oxides with hydrocarbons they form Troposphere ozone which is a secondary class of pollutant known as photochemical oxidants, amongst this class is ozone. Nitrogen oxides also react with oxygen in the air to form nitrogen dioxide which is a foul smelling brown gas and when combined with other contaminates and the atmospheric water vapor it forms brown smog, the same brown smog that can be seen over Melbourne often on a warm, clear mourning day. We are however lucky in Melbourne compared to LA for instance which experiences endless smoggy conditions. Although factories and industrial practices barrel out pollutants that baffle the motor vehicle, the motor vehicle maintains to use ½ the world’s oil and with half the words cities complaining that the biggest source of air pollution being exhaust emissions causing thousands of deaths which could have been prevented. The fuels we burn in our cars, factories and homes are hydrocarbons, a combination of only hydrogen and carbon. When they burn, after the hydrocarbon has been oxidized some of the carbon is left behind in the form of various gases. Molecules of carbon-rich gases combine into large groups and results in deposits of soot. If combustion is efficient, the chain reaction continues and the soot is completely oxidized. Combustion is not always efficient, and inefficient combustion allows the soot to escape among the hot gases. As the gases cool, the soot condenses into a solid black particle consisting of carbon mixed with ash. Water vapor from the oxidization of hydrogen also condenses, and the mixture of water droplets and soot is what we see as smoke. If the burning is not complete, then some of the carbon atoms only combine with one oxygen atom to form carbon monoxide (CO). On a whole, the burning of fuels and the natural burning of bush, grass and forest fires account for 13 million tons of the carbon released into the air as soot. The WHO or World Health Organization estimate that 3 million people die each year from pollution related illness. The catalytic converter was introduced to reduce lead and is called so because it uses catalysts substances that accelerate a chemical reaction whilst remaining unaltered. Nowadays cars are fitted with a three way catalytic converter to reduce emissions. The reason for the name, “three way” is because it reduces emissions in three substances: Carbon monoxide, volatile organic compounds (hydrocarbons) and nitrogen oxides. Although the use of catalytic converters has reduced the amount of smog causing compounds in motor vehicle exhaust emissions, recent studies have shown that the converters produce nitrous oxide which affects the nervous system, the heart and any unborn fetus. It also contributes substantially to global warming . This is however a small price to pay for a greater solution, and as this short list of pathogens found in car exhaust are as follows:
1: Carbon Monoxide 2: Nitrogen dioxide 3: Sulfur dioxide 4: Suspended particles including PM-10, particles less than 10 microns in size. 5: Benzene 6: Formaldehyde (a known carcinogen) 7: Polycyclic hydrocarbons ==
== Factory pollution is the number one source of pollutants in the United States. Contaminants of the air are classified as gases and particulates. Particulates are tiny particles which are further grouped by their sizes, the smaller the particulates are of a noxious or dangerous substance, and the more dangerous it is because it will be able to travel deeper into the airways of those who breathe it in. Factory pollution does includes carbon monoxide, a chemical which is mainly produced in combustion processes and though most carbon monoxide pollution comes from motorized vehicles, there are also many combustion driven power plants still in operation today. Factory pollution also includes chlorofluorocarbon (CFC’s), which have been shown to destroy the ozone layer, this layer reduces the amount of ultraviolet radiation that reaches the earth’s surface. Hydrocarbon gases and nitrogen oxides are also frequently emitted by industrial factories, factories causing smog. Sulfur oxides, also emitted by factories cause acid rain, the origins of which are the poisonous pathogen being emitted by the burning of fuel that contains sulfur and is mainly produced at power plants or combustion-driven power plants. There has been a 33% decrease in sulfur oxides between the years of 1983 and 2002. Sulfur dioxide comprises of three types of oxides; Sulfur dioxide, Sulfur monoxide and Sulfur trioxide, they have been known to cause acid rain. These emission reductions are believed to be due to state restrictions and over time the typical industrial factory has been fitted with various types of pollution control devices that are designed to minimize the amount of contaminants that are released into the air or water. While these and other means of decreasing pollution are somewhat effective, the pollution problem continues to be an increasing area of concern. Burning coal is however still a leading cause of smog, acid rain, global warming, and air toxics and in an average year.
“If we all were to stop driving sure it would have a detrimental effect on the earth but would it be enough to turn the world around?” No is my answer, the world is to polluted for there to be a ___still working on this bit. ==
