Kids Living Near Busy Roads More Likely To Have Asthma

Previous research showed that pollution from heavy traffic near homes can contribute to breathing problems, and now a new study finds that children who live near busy roads are more likely to develop asthma. Specifically, researchers from the University of Southern California found higher levels of asthma in kids who living within 250 feet of freeways, which they say causes 8 percent of the 300,000 cases of childhood asthma in Los Angeles.
