    In recent decades ,some area of the world is not quite stable. There are several groups that people have change to be refugees, safety issue, politically oppression and religious factor.

    Safety issue is the first group people who are easy to be retugees Especially the people Who live in the area of war , the war absolutely can cause millions of people sick . death and homeless . Their homes ruined by attacking and people have to move to somewhere safety to avoid the dangerous factor . Towards the war most of refugees were women , old people or infirm.

Politically oppression is the second group , especially the people who live in the dictatorship countries Because of the special political situation of their countries , all people have to obey the ruler of this country . if they have diiferent opinions of politician , such as some minorities and opponents . The government may treat them as threaten so these minorities and opponents is in danger if they still stay in their own country. So they have to move to another country to seek political asylum, then they become refugees.

The last group of people is who live in the religious sensitive areas . In these kind of areas , the relationship between different religions are quite complicated In ethnically diverse nations . religious and ethnic minorities should be free to use their language and maintain their traditions without fear of recrimination from the majority population . But the realities unlike what peoples hope , with the thousandyears , the religious conflicts never end , especially Middle East area.     

In conclusion , safety issue , politically oppression and religion factor are main factors to change people into refugees.
