It is regrettable that Hanoi, where I’m living, is negatively affected by pollution and the major environmental problems it is facing are water pollution, air pollution and noise pollution. There are various reasons why this city is badly polluted. Firstly, due to modernization, more and more vehicles such as cars and motorbikes are used. This leads to an increase in exhaust emissions which contaminate the atmosphere, not to mention the rising level of noise pollution. Secondly, factories and industrial zones in the city have discharged a huge amount of untreated waste into rivers, causing death to many fish and other aquatic animals. In fact, pollution makes people here less healthy, and some even suffer from life-threatening diseases such as lung cancer, skin cancer, and so on. Therefore, the government must deal with this problem right away. Cutting down on vehicle use is the best way to reduce air pollution and noise pollution. We can do this by encouraging people to use public transportation. Besides, those who litter should pay a heavy fine. Finally, I think the best solution is to raise awareness and educate people to protect the environment.
