Asthma is a medical problem. It makes it hard for you to breathe. You have it all your life. Doctors cannot stop it.
Scientists study traffic pollution and asthma. They find out that traffic pollution connects to asthma in children. Scientists learn this from 194 countries and 125 big cities. The study shows where most pollution is.
People say that we need to make changes. We can change the rules for pollution. We can have cleaner transportation.
Difficult words: breathe (get air in and out of your body), pollution (smoke which comes from cars, planes, and ships), connect (it has something to do with it).
