Clean Air Facts
Where does air pollution come from?
Most of the air pollution (about 70%) in our area comes from all the cars and trucks driving around your town and highway. Other sources of air pollution are from businesses, residential outdoor and indoor burning, agricultural burning, and industries.
How is air pollution formed?
Pollution can form when different pollutants combine and react together in the sunlight. They "cook" in the hot summer sun. This is called ground-level ozone. It mainly comes from vehicle exhaust, but can also come from lawn mowers, tractors, chainsaws, motor boats, water and ski dos. Ground-level ozone is unhealthy for us to breathe into our lungs.
A thin layer of gases that surrounds the earth, called the ozone layer, also causes pollution. The earth's atmosphere is mostly made up of nitrogen and oxygen. It also has water droplets, fine particles, and small amounts of carbon dioxide, nitrous oxide, methane, and other gases. Some of these have been in our atmosphere for millions of years, coming naturally from volcanoes and forest fires. Today, humans are the main reason for air pollution. We can see the results from humans in smog over our cities.
Is air pollution a problem where we live?
Yes, some of the time. We live in a valley that is surrounded by mountains on both sides, so the area we live in is shaped like a bowl. Air pollution gets trapped in the bowl on hot summer days and cold winter days when the air is not moving. When this happens, pollution can build up. After several days, our air can be unhealthy to breath. The air will stay like this until the wind finally blows it away.
Why do we need cleaner air?
Even healthy people can feel the effects of air pollution (itchy eyes, sore throats, and shortness of breath). Kids, like you, whose lungs are still growing, can be affected more than adults! Air pollution makes your heart and lungs work harder to get oxygen into your body. It can even make your lungs age faster, so that as you get older, you'll have a hard time breathing. Air pollution can also contribute to diseases like bronchitis, emphysema, and cancer. So it's important for everyone to fight air pollution whenever they can!
