Unit 2: Transportation and Air Pollution: Impacts and Consequences

These lessons discuss and explain the combustion process and past and current efforts to make gasoline burn cleanly. Students will learn how vehicles contribute to air pollution and about the health consequences of polluted air. Students will study a diagram of how ozone is formed and how it travels, and by researching, students will learn if they live in a non-attainment area.

A key point for students to understand is that with small numbers of vehicles in operation, their impact on public health and the environment is relatively small. With large numbers of vehicles in use, the problem grows. In choosing new fuels for vehicles, we need to consider the health and environmental impacts of an ever-growing number of vehicles using them. In 1999, the world population reached 6 billion; it is expected to reach 9 billion by 2050. In addition to the rapidly growing world population is the even faster growth of energy consumption taking place as standards of living rise throughout the world, making it urgent to find ways to reduce our use of fossil fuels.
