The cartoon vividly reveals the phenomenon of air pollution or the decline of
air quality. What exactly contribute to this phenomenon? Possible reasons can be
listed as follows: firstly, vehicle exhaust gases could be one of the most
leading causes. With the improvement of economy and people’s living standard,
urban inhabitants in mounting numbers own their private cars.
More automobiles
will inevitably generate more exhaust gases. Additionally, household appliances
widely used in cities also release a great mount of carbon dioxide gases, which
further intensifies air pollution. Last but not least, many factories around the
cities emit large quantities of untreated poisonous gases, which should also be
responsible for the decline of air quality.
Definitely, air pollution will exert a detrimental impact on many aspects of
people’s life. For example, many diseases such as cough, skin problem and lang
cancer are caused by it. Perhaps it is high time that we should adopt some
measures to solve the problem of air pollution.
