As we know, cities are the meeting points of culture and people. In the big cities, you will find many factories and enterprises. I think it is also a factor which lead to air pollution – the most serious problem in the big cities.
Air pollution is a major change in the composition of the air, mainly due to dust or gases being released into the air. I suppose that air pollution is due to two main factors:
One is the natural factors such as: forest fires, dust storms, … Another is human factors like: Industry, transportation or daily activities in people’s lives .
Air pollution has caused many consequences: it has killed many plants, animals, and it leads to many diseases for humans such as cancer …
So how to overcome this situation where the air is heavily polluted in the big cities? I would like to put forward some measures:
Firstly, replacing the machines which cause much pollution .
Secondly, limiting the construction of industrial areas in the big cities .
Thirdly, encouraging people to travel by public transport to reduce smokes and fumes.
To sum up, I hope that my measures above are useful to dealing with air pollution in the big cities. Air pollution is a serious problem and is not easy to solve it immediately but anyway, people should figure out how to prevent it with their ability.
