How can global conflicts affect population distribution?

Global conflicts significantly impact population distribution primarily by leading to refugee crises. When conflicts break out, whether due to war, civil unrest, or persecution, individuals and families are often forced to flee their homes to seek safety and stability. This mass movement of people creates significant shifts in population demographics, as large groups relocate to neighboring countries or urban areas, often leading to rapid changes in population density in those regions.

As people flee from conflict zones, they may overcrowd host areas, affecting local resources, infrastructure, and services. This can create new social dynamics and challenges for both the refugees and the host communities, as the latter may struggle to accommodate the influx of new residents.

In contrast, the other options do not directly address the primary consequences of conflict on population distribution. While global conflicts may influence agricultural output or trade in indirect ways, these factors do not encompass the immediate and significant movements of people associated with crises. Similarly, conflicts generally disrupt rather than stabilize migration patterns, thus not contributing positively to the distribution of populations across regions.
