Floods are the most dangerous natural disasters in the world. A flood is an overflow of water on normally dry ground. And floods always occur in Vietnam, especially in central Vietnam. Nowadays, human activities affect the environment a lot, such as They chop down trees in the forest, the people are overpopulated, burn fossil fuels, and that's why floods are more frequent.
