Provide an example of catholic social teaching. Explain how you, as an 8th Grader work for justice and peace?

I work for justice by standing up against bullies and being a peacemaker when things get heated between people. I try to make it so that we can all live in harmony and realize that we are all children of God and should love each other as He loved us. (Sorry if this isn't Catholic enough I'm a Christian personally but I tried I promise)
