Air pollution is a huge global issue. We breathe in tiny specks every day. These particles are called particulate matter, or PM. They come in different sizes, like PM10 and PM2. 5. When we inhale them, they travel all the way down into our lungs. This isn't just harmless dust. Scientists know these
