All humans are not equal. People are different in many ways such as their ethnicity, belief or religion. According to their difference, there are many disagreements between these groups of people. If we review our history , there were many conflicts. Some conflict may small. Some conflict may big. But we can exactly say that all conflict bring only disadvantages to the people. Conflict are usually seen in those who have different ethnicities and believes.
Ethnic conflict bring many disadvantages and sometimes bring inhumanity. Rwanda genocide is caused between Hutu and Tutsi people. These two races have same religion and live in the same country. In 1994 , the plane which carry Hutu president was destroyed by Tutsi. They declare to kill all Hutu in Rwanda. So , the conflict between Hutu and Tutsi started. They killed each others cruelly. They even putting to death the children. A lot of people moved from their home. A lot of people lost their family. It took about 100 days and deaths are between 500,000 and 1,000,000 , about 10% country population. These are the result of conflict. Another example is 6 million of Jews were killed by Nazi in World War II. Some Jews were killed with fire, some were with poisonous gas and some were as human subjects in research.
Within previous few centuries, most of conflicts were caused by the people who have different believes. For example, people in North Korea and South Korea have same language, same ethnicity and same culture. They lived in same land together since over thousand years ago. But their believes divided their country into two parts. People from northern part wanted to build a communist society and communist country. Southern people disagree. Their believes made the conflicts. Many conflicts are caused such as between capitalism and communism, dictatorship and democracy, capitalism and socialism , communism and socialism.
We all are lived in the same world together. People are in the different ethnicities and different believes. If there is a lot of conflicts, we cannot find the peace in the world. So, we need to understand between another different people. We should avoid conflict between one another.
