The Clean Air Act is a law that makes sure the air we breathe is clean and healthy. It was made in 1990 by the government to help protect us from pollution. Pollution is when harmful things get in the air, like smoke from factories and cars.
The Clean Air Act helps keep the air clean in a few ways. It sets rules for how much pollution factories and cars can make, and it makes them work to reduce their emissions. It also creates programs to help people be more aware of how to help keep the air clean.
The Clean Air Act is important because when we breathe polluted air, it can make us really sick. It can make it hard to breathe, give us asthma or lung problems, and even cause cancer. By having the Clean Air Act, we can make sure we have cleaner air to breathe and help us stay healthy.
