Wildfire Smoke From Canada Reaches the U.S.

Thick, toxic smoke from wildfires in Canada is spreading into the United States. This smoke heavily obscures the blue sky, turning it a milky-white or orange. This occurrence has become a frequent aspect of summers as uncontrolled wildfires in the West send hazardous smoke downwind.

The smoke impacts air quality, prompting precautions for outdoor activities. For instance, a cyclist in Washington, D.C., wore a mask while navigating through the haze. The effects underscore the broader environmental and health concerns associated with recurring wildfires.
