The drawing subtly reflects that air pollution is becoming increasingly serious in big cities. In the cartoon, there are a large number of cars, buses and trucks driving on the road, and the air quality is extremely bad. Meanwhile, a good many people are constantly coughing in their offices and homes. The magnifier reads: "PM 2.5".

Recent years have seen a rapid increase in the number of urban motor vehicles. Their emissions contribute significantly to air pollution and are a major ingredient in the creation of smog in some large cities. The smog's most threatening aspect is its high concentration of PM 2.5-particulate matter that is small enough to lodge deep into the lungs and enter the bloodstream. No wonder that sometimes people have difficulty breathing or keep coughing.

In my view, it is imperative for us to take measures to reduce vehicle emissions, in terms of fuel quality and vehicle emission reduction technologies. Moreover, planting more trees can benefit air quality and the health of city residents.
