<em>The three major cases of mass migration today are civil wars, disease, and famine.</em>
Migration is one of the most difficult issues nations are facing in today's modern world. Hundreds of thousands of people have to leave their native countries for different j¿kind of reasons such as civil wars, , and famine.
Civil Wars. Middle East countries such as Syria is living a terrible civil war that is forcing thousands of people to emigrate to other countries. Cities such as Aleppo, Syria, are completely destroyed. Diseases are another factor. Countries in Africa suffer from terrible diseases such as Ebola, and people move to other places where they can find health services. Famine is the constant reason for migration. The example is what is happening right now in Central America. People from Honduras, Nicaragua, and El Salvador are leaving by thousands their native countries, crossing through the Mexican territory to get to the United States. This has caused a humanitarian problem to attend thousands of people from Central America that are strained in the US-Mexican border.
