I live in Tehran, Iran with my family. The air is extremely polluted here, and the government produces (or maybe imports) low-quality gasoline which has caused severe pollution. In 2008, we had very severe pollution. Since then, we have had this kind of severe pollution every now and again, but last year it was almost choking us. The tall buildings around Tehran trap the bad air. It affects my family because my father has pulmonary fibrosis, and this air is too polluted for him to breathe well.
