Baoding is considered one of the most polluted cities in the world. With over 10 million people, this is a major health concern to everyone living n the city. After discovering the air pollution figures, officials realized the city only had 16 days of “good” quality air levels, considered safe for people to live in. That’s horrible. That means every other day was considered an unsafe air quality level.
Mr. Han, a local who’s living in Baoding his whole life, said, “generally, there is smog on most days. It was much better when I was young, the air was very clean. We rarely see blue skies now.” Nowadays, the pollution comes from coal stacks and air factories that pump out toxic fumes into the air, even though it might not seem obvious (The Guardian).
