Asthma from traffic

Asthma is a serious medical condition because it is lifelong; there is no cure. A study says that pollution from traffic connects to 4 millions new cases of asthma in children each year.

Researchers studied the pollution and how it affects children's health in 194 countries and 125 large cities.
