What are the impacts of smog?
Smog affects our health. When ozone is closer to the earth's surface in a layer called the troposphere, it can harm our health. Exposure to ozone can cause asthma attacks, lung inflammation and other respiratory illnesses. High levels of ozone pollution cause discomfort for people with asthma or other lung ailments. Ozone may damage lung tissue even in healthy people. It makes our eyes itch, burn and water. Even healthy people can be affected if they exercise outdoors.
