Rationing is a system used to control the distribution of scarce resources, such as food, fuel, or other essential goods. It ensures that everyone receives a fair share during times of shortage, such as during wars or natural disasters. Governments often implement rationing to prevent hoarding and ensure that supplies last longer. During World War II, for example, many countries introduced rationing to manage limited resources. Citizens received ration books that allowed them to purchase a specific amount of items like sugar, meat, and gasoline. This helped maintain order and equity in society during challenging times.
