Canadian Wildfire Smoke Spreads Across Wide Areas in the United States

The article explains that the wildfires raging in Canada pose a threat that extends beyond local borders, spreading across large areas of the United States. The skies over cities such as New York, Chicago, and others have been covered with thick yellow smoke, leading to a severe deterioration in air quality. According to the U.S. Environmental Protection Agency, pollution levels reached nearly 700 parts per million in the late afternoon—much higher than the permitted threshold—prompting health warnings and residents to stay indoors. Additionally, sporting events were canceled due to the worsening air quality, and it is expected that the impact of the fires on air quality will continue in the near future.
