H:Good morning,listeners.Air pollution is a serious problem,with urban

populations particularly at risk from smog.Ben Drake is an expert on air pollution,and

H:That sounds terrible! What problems did it cause?

BD:Smog caused many health issues and killed many people.The worst case

move away from city centres.

H:But smog is still an important issue in many places.What can be done about

it?

BD:Smog is harmful to everyone,especially to children,old people and those

with heart or lung problems.We have to reduce smog and improve air quality for

everyone’s health and wellbeing.We should replace coal with cleaner forms of
