Answer:
True
Step-by-step explanation:
Despite the cost of life, war has adverse effects on the economy. War disrupts the economy in the following. 
- Loss of infrastructure. In times of war, many buildings, roads, and bridges get destroyed. The loss cripples economic activities in a country. 
 - High inflation. War causes inflation to rise, thereby eroding people saving. 
 - Rise in national Debts. During the war, governments tend to borrow more money, partly to finance the war.
 - Opportunity cost. War is expensive. The government spends a lot of money on the military and weapons instead of development. 
 - Loss of livelihoods. In times of war, many economic activities come to a halt. Imports and exports become difficult. Industries lack raw materials, while many businesses close down.
