Nearly Half Of U.S. Kids Breathe Unhealthy Air

Since the Clean Air Act passed in 1970, air pollution fell dramatically across the country. It was a genuine achievement and advancement for American citizens.

Now, thanks to Trump dismissing scientific evidence linking greenhouse gasses to health issues and forcing EPA to deregulate all sources of environmental pollutants, dangerous particles and ozone levels are on the rise once more, leaving nearly half of U.S. children and teens breathing unhealthy air every day.

The American Lung Association has issued a warning based on its latest State of the Air report: 44% of the U.S. population reside in areas with unhealthy levels of pollution, including 33 million who are younger than 18. Kids and seniors are most at risk for the harmful effects of ozone and particle pollution.

The report's authors warn, "Contrary to its mission, EPA has recently acted to weaken, delay or revoke key health protections that will leave America's children more exposed and more vulnerable to the consequences of many different pollutants, including ozone and particle pollution."
