During every major war, there was food rationing to make up for the lack of agricultural production. The same will happen when World War III comes around, which could lead to an engineered food shortage.
With so many farms turned into battlefields and transportation networks disrupted during WWI, it wasn’t easy to get food to the stores. That’s why the U.S Food Administration was created on August 10, 1917, just after the US entered the war.
It was set up to manage the war effort by providing food, protecting it, distributing it, and transporting it. According to History.com, President Woodrow Wilson appointed then-President Herbert Hoover, who also created a voluntary program to encourage Americans’ compassion and patriotism.
