Problem tree

Hi everyone!
Here is my problem tree. http://www.scribd.com/doc/47544866/Problem-tree

The trunk:

Everybody knows that minorities are often discriminated. After the events in December, 11 in 2010 in Moscow I realize that the level of the problem is skyrocketing and it needs solution.

The root:

• Prejudices
• Politics (political disturbances provoked by several acts of terror in Caucasus and Russia lead to misunderstanding between the peoples)
• Ignorance (many people don’t know/use effective strategies of conflict solution)

The leaves:

• Murders, acts of terror
• Conflicts
• Misunderstanding between people
• Fears
• Demorailization

I`m still working on it and accept suggestions.
