Air pollution levels keep getting worse for more people in the US, according to a new report, and experts say the Trump administration’s proposed deregulation plans will make it even harder for people to get clean air.

The American Lung Association report finds that climate events are causing more people in the U.S. to breathe toxic air even as other pollution falls.

The American Lung Association has revealed that nearly half the U.S. population resided in areas with dangerous levels of air pollution between 2021 and 2023.
