Why would you have to move in the case of a famine?

In the case of a famine, moving may become necessary due to the scarcity of food and resources in the affected area, which can lead to hunger and malnutrition. Relocating to a region with more abundant food supplies can help ensure survival and better living conditions. Additionally, migration may be driven by social, economic, or political instability that often accompanies famine, making it difficult to sustain a viable lifestyle in the original location.
