What is the focus of the Clean Air Act?

• A. Controlling water pollution
• B. Controlling air pollution emissions
• C. Protecting wildlife and fisheries
• D. Regulating hazardous waste

Answer: (B)

The Clean Air Act aims to improve air quality by regulating air pollutants and setting national standards for air quality. Its primary focus is to control emissions of harmful substances from various sources such as factories, automobiles, and other industrial activities. By establishing limits on the amounts of specific pollutants that can be present in the atmosphere, the Act seeks to protect public health and the environment from the adverse effects of air pollution. This legislation has been pivotal in reducing smog, acid rain, and other air quality issues, thus promoting a healthier environment for all living beings.

The other options pertain to different aspects of environmental protection, such as water quality and hazardous waste management, which while all important, do not represent the specific goal of the Clean Air Act.
