Nearly Half of Americans Exposed to Unhealthy Air Quality, New Report Reveals

A recent report by the American Lung Association highlights a concerning trend: nearly 156 million Americans are living in areas with unhealthy air quality. The annual "State of the Air" report, which analyzes data from 2021 to 2023, found that conditions such as smog and soot pollution are worsening, reversing some progress made since the enactment of the Clean Air Act in 1970. Despite overall improvements over decades, recent years have seen pollution levels inch upward, largely attributed to climate change effects like wildfires and extreme heat.

The report identifies Bakersfield, California, as the city with the most persistent and severe particle pollution, marking its sixth consecutive year at the top for worst air quality. Conversely, Casper, Wyoming, was ranked as the cleanest city for year-round pollution levels.

The consequences of these pollution levels are severe, with air pollution linked to asthma, cardiovascular diseases, lung cancer, and cognitive impairments. Vulnerable populations, including Black Americans, are disproportionately affected, experiencing higher rates of health complications.

Environmental experts emphasize that wildfires, not just locally but originating from distant regions such as Canada, significantly impact air quality across the U.S. The report also warns against recent policy moves, such as the U.S. EPA's decision to roll back 31 environmental regulations, including vehicle emission standards. Critics argue that this deregulation threatens to undo decades of progress in air quality improvement, putting public health at risk.

Health advocacy leaders stress the importance of strong policies to maintain clean air standards, especially in the context of ongoing climate change, which exacerbates pollution from wildfires and heatwaves. Protecting air quality remains a vital public health priority to prevent respiratory and systemic health issues for all Americans.
