Smoke from fires in Canada is traveling thousands of miles. Here’s how to protect yourself

Wildfires in Canada are spewing smoke that's traveling across the continent, affecting cities like Chicago and New York, and even set to reach Europe next week. These tiny PM 2.5 particles, much smaller than a human hair, can cause serious health issues by entering lungs and bloodstreams. It's crucial to take precautions if you notice a hazy sky, as even distant smoke carries significant health risks. This widespread impact highlights the interconnectedness of global environmental issues and the need for awareness and action.
