Chicago's Air Quality Improves, But Ignored State Continues to Neglect the Issue

Chicago's air quality has improved slightly from "very unhealthy" to "unhealthy" due to smoke from Canadian wildfires. The city remains in the red "unhealthy" zone, with officials urging residents, especially the young, old, and medically fragile, to take precautions. Measures such as keeping windows and doors closed, limiting driving, and using public transit are encouraged to minimize additional air pollution. People with respiratory illnesses are advised to avoid being outdoors. The Illinois Environmental Protection Agency issued an Air Pollution Action Day alert, and the city is providing personal protective equipment and respite locations for vulnerable residents.
