In city life, there is a serious issue of the increase in the level of contaminated atmosphere. ＋In this essay, I will show the primary causes of it, vehicles’ emission and its main consequence is citizens’ health being affected.

To begin with the principal reason, the emission from vehicles, especially old transportation which uses fuel for operating, creates CO2 two or three times more than electric vehicles. Therefore, greenhouse gases are produced variously, like methane and CFC, etc. Following the primary cause is unprecedented urbanization, the emergence of urbanization without suitable infrastructure, for example limited green spaces, have trapped toxic gases in city boundaries. In general, the cause of air pollution is densely populated urban centers and inefficient city systems.

Consequently, residents living in poorly planned urban areas suffer severely from continuous exposure to traffic emissions. When people breathe in this dirty air every day, it directly harms their lungs and bodies. In the long term, this critical air quality leads to chronic lung diseases like asthma or lung cancer, which manifest through severe worst symptoms such as shortness of breath, chest pain, and wheezing. Moreover, these illnesses force many citizens to miss work or school, which significantly lowers the quality of life and places a heavy burden on public healthcare systems.

In conclusion, both poor infrastructure and high volumes of traffic emissions are the primary drivers of air pollution in urban centers. This critical issue not only degrades environmental quality but also poses severe, long-term risks to public health.
