* Create refugees and internally displaced persons. Wars often force people to flee their homes and communities, either as refugees or internally displaced persons (IDPs). This can lead to a humanitarian crisis, with people lacking access to basic necessities such as food, shelter, and healthcare.
* Disrupt economies and livelihoods. Wars can disrupt economic activity and livelihoods, leading to poverty and unemployment. This can have a long-term impact on the development of a country or region.
* Increase political instability and human rights abuses. Wars can lead to political instability and the rise of authoritarian regimes. They can also lead to human rights abuses, such as torture, arbitrary detention, and extrajudicial killings.
* Spread disease. Wars can spread disease, both during and after the conflict. This is due to a lack of access to healthcare, poor sanitation, and the displacement of populations.
* Cause environmental damage. Wars can cause environmental damage, such as pollution, deforestation, and soil erosion. This can have a long-term impact on the health of people and the environment.
* Have a negative impact on mental health. Wars can have a negative impact on mental health, both for those who are directly affected by the conflict and for those who are indirectly affected.
