As smoke from massive wildfires in Canada engulfs parts of North America, alarming air quality alerts have been issued across multiple U.S. states. Cities like Chicago, Toronto, and Detroit are experiencing some of the poorest air quality levels globally, prompting health concerns and recommendations for residents to stay indoors. The Great Lakes region is particularly affected, with ongoing smoke issues predicted for the summer months. Health officials note a significant uptick in emergency room visits due to respiratory issues caused by the smoke. With forecasts indicating that the impact may extend even to Europe, citizens are urged to take protective measures against the adverse effects of this environmental crisis.
