Climate expert Bill Becker writes here about the state of America’s air, and Trump’s rollback of regulations to improve its quality.

He writes:

Our air still is not as clean and healthy as it could be, or should be. The most recent “State of the Air” report from the American Lung Association (ALA) includes the sobering fact that nearly half of the American people live in places where it is still dangerous to breathe. Between 2016 and 2018, air quality has actually gotten worse. Over those three years, “millions more Americans were living in communities impacted by unhealthy levels of pollution in the form of more unhealthy ozone days, more particle pollution days and higher annual particle levels.”

Nearly 46% of us (that’s about 150 million people) live in counties with unhealthy levels of those pollutants. Ozone and particulates contribute to a variety of potentially deadly lung-related problems including asthma, heart disease, lung cancer and the basic functions of the lungs. Like so many other problems, from COVID-19 to the deadly consequences of climate change, people of color and low-income families suffer most…

The Trump administration…has significantly weakened enforcement of the Clean Air Act. Trump killed the rules the Obama Administration created to limit emissions from power plants and to make vehicles more efficient. Trump’s weakening of vehicle efficiency standards is expected to allow cars and trucks to emit a billion more tons of heat-trapping carbon dioxide. Since President Trump took office, his administration has rolled back 27 regulations to limit air pollution, part of the 100 environmental safeguards it has reversed, revoked, or weakened. Most recently, the Administration is taking steps to stop counting the health benefits of enforcing the Clean Air Act, a move that policy experts and environmentalists say will make it harder to justify federal limits on air pollution.

To make matters worse, Trump has stopped all progress in the nation’s effort to limit climate change at the same time he is helping oil, gas and coal companies increase production of the fuels responsible for global warming and the air pollution described by the ALA.
