Human On the Death Sentence:
We Pay What We Done… or Not
For most Americans and around the world, the automobile is an essential part of daily life especially for “every second is money” and hate waiting type of people. Cars have shaped our culture, landscape. Moreover, the industries that build and serve cars form shaped our economy. The automobile is not without its faults, but they often are concealed by the styling, performance and other features that make today’s vehicles so desirable. However, when a product is so widely used, its faults can add up to massive unwanted side effects. For example, global warming is one of the side effects that motor vehicles play a ...view middle of the document...
Global warming is the increase in the average temperature of Earth's near surface air and oceans. In addition, an increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of deserts because of the heat. For the same reason, Arctic will take the toll strongest because it is the coldest area of the world with glaciers and sea ice. Furthermore, other effects of the global warming include more frequent and intense precipitation events, extreme weather events, species extinctions due to shifting isotherms, and changes in agricultural yields which it changes vary from region to region around the globe. As a result of contemporary increases in atmospheric carbon dioxide, the oceans have become more acidic.
According to Intergovernmental Panel on Climate Change (IPCC), global surface temperature increased during the 20th century because of increasing greenhouse gases, which result from human activities such as the burning of fossil fuel and deforestation. The fossil fuels, which contain high percentages of carbon, are the raw element before it becomes petroleum. Afterward, it becomes gasoline and other fuels and derivatives, example, wax and lubricants after complicated process in oil/petroleum refinery.
In figure 2.1a, transportation is the second largest energy consumed in United States – 29% in 2009. Just in one year, United States produced 5,426 million metric tons carbon dioxide (MMtCO2) which about 17.6 million metric tons per person according to Table 1. Same source, petroleum seizes in transportation sector which indicates this is one of the answers for causing increasing greenhouse gas. Even though we are promoting “go green” to save energy to save Earth, United States Energy Information Administration (EIA) did not felt optimistic in the future of transportation. In Table 1, EIA predicted U.S will emit 2,023 MMtCO2 compare to 1,816 MMtCO2 in 2009 which telling U.S will use more petroleum gasoline than before, however, U.S will produce less MMtCO2 in future as in overall.
What Now Than…Switching from Automobile to Public Transportations?
After knowing what causing in increasing greenhouse gas, we can now make some adjustments to save ourselves and the planet. However, is that even true for switching from driver to rider will lower the emission? Majority will answer the question with, “Yes” and follow with some reasonable reasons, for example, compare a person drive in his car with no passenger will emit more than a bus with full loaded of passengers. It is true; however, the transportation’s engine is different than car’s engine in many sectors. For example, transportation’s engine is bigger and more powerful than a car with a V6 or V8 engine. In this case, is not it the public transportation emits way greater than cars combine? In other word, does bus transit really reduce greenhouse gas emissions and big differences in other places?
