Canadian Wildfire Smoke Causes Haze and Air Pollution in New York City

Smoke from wildfires in eastern Canada has caused unhealthy air quality conditions in parts of the eastern U.S., including New York and New Jersey. The smoke has been so dense that people can smell it in the air. Air quality alerts have been issued for several regions, with some areas listed as having "unhealthy for sensitive groups" air quality conditions. Exposure to the pollution can cause inflammation and weaken the immune system, particularly in vulnerable groups. Experts advise checking air quality alerts regularly and keeping pets indoors as much as possible.
