World Peace!

What are some outthere type conditions needed for the world to be as one and everybody could live happily?

Here are some i've thought of:
-An end of trade (and in the process "greed" entirely)
-Solve world hunger
-Agreement of religion
-Agreement of morals, yet completely open to new morals that may develope

Basically, i've watched Star Trek TNG and I like how they've done it.
