World Asthma Day 2023

Organizations and Iowans Call for End to Coal Pollution that is 

Driving Asthma Cases

Event on World Asthma Day Underscores Link Between Coal Plants and Asthma

May 2, 2023 - Today, on World Asthma Day, organizations and Iowans gathered in Muscatine to talk about the health effects of air pollution, and to plead with MidAmerican Energy to close its coal-burning power plants by 2030, as many coal plants around the country have promised to do.

When the captive customers of MidAmerican Energy pay for their power, they may not realize that pollution from the coal-fired power plants producing their electricity jeopardizes their lives and health. Yet, MidAmerican’s refusal to transition to a true clean-energy future results in 90 premature deaths of Iowans every year according to the Sierra Club’s recent “Out of Control: The Deadly Impact of Coal Plant Pollution” report.

“The Muscatine community has carried enough of the burden of air pollution from coal fired power plants. With new incentives from Congress, the time is now to transition to a cleaner energy future,” said Katie Rock, Iowa Campaign Representative for Beyond Coal, Sierra Club.

The American Lung Association’s new “State of the Air'' 2023 report highlights how year-round exposure to particle pollution, from sources such as coal plants, is linked to a wide array of serious health effects at every stage of life, from conception through old age. These health impacts include:

  • Reduced lung development and impaired lung function in children 

  • Higher likelihood of children developing asthma

  • Increased risk from existing cardiovascular and respiratory disease in adults, including a worsening of heart disease, atherosclerosis and COPD

  • Higher likelihood of adults getting lung cancer and of dying from it

The State of the Air report also includes asthma total is several counties that have MidAmerican coal plants, including:

  • Muscatine County: 598 pediatric asthma cases and 2,968 adult asthma cases out of a population of 42,688

  • Pottawattamie County: 1,258 pediatric cases and 6,552 adult cases out of population of 93,304

  • Scott County: 2,361 pediatric cases and 12,281 adult cases out of population of 174,170

  • Woodbury County: 1,592 pediatric cases and 7,235 adult cases out of population of 105,607

Iowans gathered near a coal plant in Muscatine to call for an end to MidAmerican’s pollution that is endangering the lives of Iowans. Speakers at the event included Karin Stein of Moms Clean Air Force, Dr. Robert Blount, MD from the University of Iowa, Katie Rock with Sierra Club’s Beyond Coal Campaign in Iowa, and Alyson Glynn who has been impacted by asthma in a coal community.

"Coal-fired power plants are an infamous source of toxic pollution.  They spew mercury and 80 other dangerous air pollutants, from arsenic to acid gases, to the carbon dioxide that is warming our planet.  A disproportionate number of people of color in the United States live within 30 miles of a coal-fired power plant.  That is true in Muscatine, as well as in some other places in Iowa where MidAmerican coal plants operate.   Statistics aren’t statistics.  Statistics are people’s lives.  Let’s never forget that.", stated Karin Stein of Moms Clean Air Force
