How can you limit air pollution exposure?
A. You can buy more fuel-efficient cars, drive less, and walk more. Over the last 30 years we've reduced the amount of visible air pollution by cleaning up factories and auto emissions. But even though cars run a lot cleaner, we have more cars on the road and poor public transportation in many areas of the country, which is something that cities and states need to address. You can take steps to reduce pollution in your own home. If anybody smokes, he should do it outdoors; 40 percent of kids are still exposed to cigarette smoke. If you have a fireplace or a wood-burning stove, make sure it's well ventilated. And if your child has allergies or asthma, get rid of wall-to-wall carpeting and heavy drapes, both of which trap dust and particles.
