1. Gasoline: Fuel shortages occurred due to increased military demand and disruptions in production and transportation.
2. Rubber: With Southeast Asia falling to the Japanese, there was a severe shortage of raw rubber for automotive tires and other industrial uses.
3. Foodstuffs: Food rationing was necessary in many countries because of disruptions in transportation and decreased agricultural production due to manpower depletion from war mobilization.
4. Metals: Steel, copper, aluminum, and other metals experienced shortages as raw materials and production facilities were redirected toward military usage.
5. Consumer Goods: The production of electronics, household appliances, cars, and other consumer items significantly decreased or even paused for the duration of the war.
6. Medicines and Supplies: Access to pharmaceuticals, medical equipment, and basic living necessities became problematic because of the scarcity of materials and infrastructure strain.
Overall, the impact of World War 2 created widespread resource shortfalls, requiring governments and societies to carefully allocate and conserve what was available during those challenging times.
