More than half of U.S. residents—154 million people—suffer from polluted air that is often too dirty to breathe. This troubling statistic comes by way of the American Lung Association’s most recent State of the Air report. In 366 counties across the country, residents are inhaling dangerous levels of ozone pollution and fine particles, which are a major cause of premature death.

At the same time that these 154 million Americans are breathing dirty air, many of their representatives in Washington, D.C. are busy trying to dismantle the Clean Air Act. These allies of dirty industry think that limits on air pollution are unreasonable. They think cement kilns, power plants and other major sources of air pollution should be able to pollute without making any efforts to control toxic chemicals and metals that impact our health.

Well, I bet those 154 million Americans disagree. Our lives depend on clean air. Thankfully, more than 80 doctors, nurses, faith and tribal leaders, and community advocates from all 50 states are arriving in Washington, D.C. today to tell decision makers that we all have a right to breathe clean air.
