What is the Clean Air Act aimed at doing?

The Clean Air Act is designed to control air pollution on a national level, serving as a critical piece of legislation in the United States aimed at protecting air quality and public health. It empowers the Environmental Protection Agency (EPA) to set and enforce air quality standards that regulate emissions of hazardous pollutants from various sources, including industrial facilities and motor vehicles. By establishing these standards, the Clean Air Act works to minimize the impact of air pollution on both the environment and the health of the population. This proactive approach helps ensure cleaner air, which is essential for improving public health outcomes and promoting ecological sustainability.

Other options, such as increasing air pollution or encouraging more vehicles on the roads, contradict the legislative intent of the Clean Air Act, which seeks to reduce pollution and protect air quality. Similarly, the notion of reducing public health regulations goes against the core goals of the Act, which focus on safeguarding both the environment and the health of individuals from the adverse effects of pollution.
