8. Chad
Score – 14
With Chad it’s not so much about how polluted the air is, but rather the lack of sanitation, as only about 12 percent of the country’s inhabitants have regular access to proper sanitation methods.
On the other hand, people in Chad are at least somewhat protected from cigarette smoke as smoking has been prohibited in all indoor public places, workplaces and public transportation, while tobacco advertising has been prohibited. At the very least this should help those who suffer from asthma.
