Why It's Important?
The severe air pollution in Chicago highlights the widespread impact of Canadian wildfires, affecting air quality across large parts of North America. This situation poses significant health risks, particularly for vulnerable populations, and underscores the need for effective environmental policies and emergency response strategies. The recurring nature of these events suggests a potential new normal driven by climate change, necessitating increased awareness and preparedness among communities and health officials.
