The issue that the automobile production is a double-edged sword is rather complex, since it involves a conflict between industrial expansion and the strategy of sustainable development. However, the final judgment should depend on a case-by-case analysis of several key factors.
Since the 1960s, the world has witnessed some dramatic changes in the automobile technology. As a result, a growing number of transport vehicles have been manufactured, thus providing citizens with growing convenience and efficiency. Additionally, some economists believe that automobile production contributes to the national economy by paying more tax and providing more job vacancies. For example, In the United States or Japan, automobile industry remains the backbone of their marketing economy, the primary source of national wealth and the major provider of jobs. However, in some other instances, the above-mentioned situation is not always adequate. For instance, suppose a car that is poorly designed and gives off such poisonous gas as monoxide, methane or acetylene. Surely enough, the more cars a company manufactured, the more likely automobile production should be responsible for the environmental degradation of urban regions and the worsening health of the citizens. Another exception to this approach is the case of traffic congestion. Admittedly, when vehicles of various kinds rush to the same avenue, traffic jams invariably occur, which always gives rise to delays or accidents. These are exceptional cases, yet they do exist.
Given the analysis above, it is justified to conclude that a proper use of automobiles has to be emphasized. For one thing, governmental departments are obliged to take concrete measures to boost automobile production while keeping track of the emission of pollutants. For another thing, citizens should be aware of the corresponding side effects while enjoying the leisure of their car ride. Only in this way can they benefit greatly from the rapid growth of automobile manufacture.
