Better air in the city

You can't see it, but you still breathe it in: Air pollution is an invisible threat to millions of people living in urban areas, and many lives are lost prematurely because of it.

Researchers are cooperating with urban developers to change transport systems, reduce pollution around schools, and help citizens by measuring the air quality from neighborhood to neighborhood, even from street to street.   In this episode, we examine some of these efforts and ask the question: How can we increase the livability of our cities by improving the air quality?
