Canada Climate Wildfires Smoke

When wildfires burn, smoke can travel long distances and degrade air quality far away, posing risks to those breathing it. Fires burning in one state can make the air worse several states away, and wildfires in Canada can send smoke into U.S. cities. Here’s what to know about precautions against poor air quality due to wildfires. Experts say people should take precautions such as wearing an N95 mask while outdoors or heading inside and closing the windows. Sometimes the air is bad enough to see or smell the smoke, but even if you don’t see the pollution, it can be unhealthy to breathe.
