Translated:
I live in a suburb of a city in Vietnam. Three years ago, my neighborhood was very clean with rice fields and green trees. However, in the last 2 years, in the area where I live, several factories have appeared. They cause serious water pollution through the discharge of industrial waste into the lake. Polluted water has led to the death of aquatic animals and plants. High-rise residential buildings also replace rice fields. More people lead to more cars and motorbikes. Toxic gases from these vehicles are serious air pollutants.
