What will happen if you are asked to stay indoors always? Why would this happen anyway? Because the air out there can kill you. It’s terrible and this is soon going to happen. Due to so many human activities and natural phenomena, a lot of cities in the world are not even able to provide basic living conditions.
The air of these cities is polluted to a level where you no longer can stay a healthy life there. The smoke from factories and vehicles and refineries is one of the main reasons of this pollution. The dust storms and other natural activities are another cause. According to a survey conducted by the WHO, here is the list of the 10 most polluted cities in the world in 2018:
