In general, what major shift in the management of air pollution in the United States has occurred since 1963?
Nearly all pollutants in the United States are controlled by cap-and-trade programs. Heavy lobbying by industry has resulted in fewer restrictions and higher limits of pollutants. Regulating air pollution has largely become the responsibility of the federal government. Responsibility for regulating air pollution is shared equally between the state and local governments and the national government.
The major shift in the management of air pollution in the United States since 1963 is that regulating air pollution has largely become the responsibility of the federal government. This shift was significantly influenced by the establishment of the Clean Air Act in 1970, which empowered the federal government to set and enforce air quality standards, leading to a more centralized approach to air pollution control compared to the previous reliance on state and local regulations.
