Canadian Wildfire Smoke Engulfs US Midwest, Threatening Air Quality and Health

Smoke from wildfires in Canada is causing unhealthy air quality in the Midwest and spreading to the East Coast. Over 100 million people are expected to experience at least code orange air quality, which is unhealthy for sensitive groups. Cities like Detroit, Chicago, and Minneapolis have some of the worst air quality in the world. The smoke is a result of the record-breaking fire season in Canada, with over 483 active wildfires. People are advised to stay indoors, keep windows and doors shut, and use air purifiers. Masks are being distributed to protect against the harmful effects of the smoke.
