1. War and Conflict:
- A civil war breaks out in a country, leading to widespread violence and human rights violations. Civilians are forced to flee to neighboring countries or become internally displaced persons (IDPs) within the country.
2. Political Persecution:
- A totalitarian regime begins systematically oppressing a specific ethnic or religious group. Members of that group are forced to leave the country to avoid persecution, risking their lives in treacherous journeys across borders.
3. Natural Disaster:
- A major earthquake or tsunami devastates a coastal region. The affected population is forced to relocate to safer areas, often losing their homes and livelihoods.
4. Environmental Degradation:
- Rising sea levels due to climate change make a low-lying island nation uninhabitable. The entire population is forced to resettle in new locations.
