Today after morening tea we looked at a clip that showed the the top ten most air polluted cities in the world. Most of the cities were from the middle east. Iran had four of the top ten polluted cities. After watching it, we had these wonderings: How did the cities get that polluted? Are the cities warmer because they have got a layer of gas over them, or are they colder, because the sun doesn't get through as easy.
