What do the Clean Water and Clean Air Acts aim to limit?

The Clean Water Act and the Clean Air Act primarily aim to limit pollution in both water and air resources. The Clean Water Act focuses on regulating discharges of pollutants into the waters of the United States and establishing quality standards for surface waters. Meanwhile, the Clean Air Act is concerned with controlling air pollution on a national level, setting emission standards for various pollutants that can harm public health and the environment.

These acts were established to protect human health and the natural environment by ensuring that both air and water remain clean and safe. They provide a framework for monitoring and regulating pollutants, which helps to prevent environmental degradation and promotes sustainability.

Other options, such as noise and light pollution, fall under different regulatory frameworks and are not the primary focus of these acts. Waste management concerns are also addressed by other legislation aimed specifically at managing solid and hazardous waste, rather than directly through the Clean Water or Clean Air Acts. Thus, the overarching goal of these acts is to reduce pollution, making "pollution" the correct and most comprehensive answer.
