Almost Half of Americans Breathe Unhealthy Air, Report Finds

While air quality in the U.S. has seen significant improvements since 1970 due to the Clean Air Act, many residents still face polluted air that impacts health and life expectancy. Over 156 million people experience poor air quality for at least one pollutant, with nearly 42 million living in areas where all three standards are not met. The Biden administration has implemented stricter regulations on emissions, while the Trump administration is reversing these measures. Additionally, President Trump has directed increased coal use and investment in outdated technologies, which he argues targets unnecessary environmental controls.
