Air pollution is a major environmental problem in Vietnam, especially in big cities like Hanoi and Ho Chi Minh City. The main causes are vehicle emissions, industrial activities, and construction dust. Poor air quality affects people’s health, leading to respiratory diseases, especially in children and the elderly. It also harms the environment and reduces the quality of life.

To solve this problem, the government should improve public transportation to reduce the number of private vehicles. Factories must follow strict environmental regulations and use cleaner technologies. People can also help by using bicycles, planting more trees, and avoiding burning waste. Raising public awareness through education and media is also important.

In conclusion, air pollution is a serious issue that needs cooperation from both the government and citizens. By taking action now, we can ensure a healthier and safer environment for everyone.
