PROBLEM: Person1: What do you think are the main causes of war today ?
Person2:I ' d say the main reason is poverty . Countries and their people get frustrated because they have so little . If their neighbors have some resources , they try to steal them by military force .
Person1: It seems that a lot of wars nowadays are really civil wars . People from different ethnic groups in the same country sometimes fight for power in that country .
Person2:Several of those civil wars have been going on for years and years . It seems they will never end .
Person1: How do you think they could be ended ?
Person2:I don ' t think that there is any easy way . The united nations could send peacekeepers into the country . At least then the warring parties could be forced to negotiate . The thing is to find the real problem form the war and solve that .
Person1: So , if the cause is poverty , there should be a program to make the country richer . If the problem is resources , share them .
Person2:It sounds easy when you say it like that . In reality , it ' s harder to make peace between countries .
Person1: Yes . It is . One way to stop countries fighting is to cut off their financial support . Wars are very expensive .
Person2:The problem is that many poor people might suffer .
