Answer:
Putting aside the very real human cost, war has also serious economic costs – loss of buildings, infrastructure, a decline in the working population, uncertainty, rise in debt, and disruption to normal economic activity. Negative effects of war can include loss of life, destruction of cities and the environment, and human suffering. Positive effects of war can include the defeat of problematic governments, the correction of injustices, advances in technology and medicine, and a reduction of unemployment. hope this helps.
