Environmentally conscious individuals subscribe to the idea that driving a car is the most polluting act humans commit. According to WGBH Educational Foundation (2011), transport is the second leading carbon disoxide emitter. Automobile emissions consist of greenhouse gases or hydrocarbons such as carbon dioxide, carbon monoxide (incomplete combustion), nitrous oxides and sulfur oxides. These greenhouse gases are responsible for greenhouse effect which has led to the depletion of ozone layer. The depletion of the ozone layer, which retains the heat radiated from the surface of the earth, results into global warming and climate change. Additionally, automobile emissions can be harmful to human, animal, and plant life. Some common respiratory problems are known to result from inhalation of air that has been poisoned by automobile emissions (U.S . Environmental Protection Agency, 2011).
In the recent years, acid rains have resulted to loss of vegetation or property destruction. Automobile emissions are responsible for the generation of sulfur oxides which facilitate the formation of acid rains. Automobile emission is both a local and global problem. This is because emissions in one place, for example industrial emissions in developed countries, have their effect felt across the globe. The heavy automobile emissions are to blame for the current climate change problem that threatens human life on earth.

Zusammenfassung der Kapitel (Chapter Summaries)
Environmental Effects of Automobile Emissions: This chapter introduces the significant environmental consequences of automobile emissions, primarily focusing on their contribution to greenhouse gases and the resulting global warming and climate change. It highlights the detrimental effects of these emissions on the ozone layer and the subsequent impact on human, animal, and plant life, citing respiratory problems and acid rain as examples. The chapter establishes the global scale of the problem, emphasizing the far-reaching consequences of emissions originating in one location.
Scientific Research on Automobile Emissions: This section delves into the methods employed by scientists to study automobile emissions. It describes the process of collecting emission samples, conducting laboratory experiments under varying conditions, and using these experiments to develop predictive models of environmental impact. The chapter also touches upon the use of experimental animals and plants to assess the effects of emissions on living organisms.
Problems Faced by Scientists Studying Auto Emissions: This chapter focuses on the challenges faced by researchers in the field. It highlights the difficulty of accurately predicting future emissions, the criticisms faced from various stakeholders (including those who deny climate change), and the inadequacy of current technologies for assessing emission levels. These obstacles are presented as significant barriers to comprehensive research and accurate predictions.
Benefits of Gasoline: This chapter explores the advantages of gasoline as a fuel source. It points out its efficient combustion process resulting in relatively cleaner burning compared to other fossil fuels, its lower carbon dioxide emissions compared to alternative energy sources, and its generally non-toxic nature when inhaled in small amounts. The chapter also highlights gasoline's lack of residue and the reduced need for extensive storage infrastructure, contrasting it with other fuels like oil.
Limitations of Gasoline Use: This section discusses the drawbacks of gasoline. The inherent flammability of gasoline and the associated risks of fires and explosions are emphasized, along with the substantial economic cost of establishing and maintaining a gasoline infrastructure, particularly challenging for developing countries. The non-renewable nature of gasoline and its high demand contributing to unsustainable future supply are also discussed. Finally, the colorless, odorless, and tasteless nature of gasoline presents challenges in detecting leaks and managing potential environmental hazards.
Environmentally Friendly Technologies: This chapter examines the technological advancements aimed at reducing the environmental impact of automobiles. It details the development of new engine designs, charcoal canisters to trap hydrocarbon vapors, exhaust gas recirculation valves to reduce nitrogen oxides, and the introduction of catalytic converters and unleaded gasoline. The significance of these technologies in mitigating environmental and health problems associated with lead pollution is underscored. The chapter concludes by mentioning computerized diagnostic systems to detect emission control system defects.
