✔ 最佳答案
Wars and conflicts will lead to famine.
It is because the army will confiscate (forfeit) the food from the citizens, so that the food supply for the citizens are not sufficient and hence lead to food shortage.
Besides, the troops will trample the farmland so that the crops are destroyed.
Moreover, farmers will abandon their farmlands and flee away as the unstable situation. Therefore, the productivity of crops decreases sharply.
