DefineYour own World.

I would want all people to have equal rights to water, food, education and work that they loved.

That would be the ultimate thing to change. The next best thing is to find ways to prolong life.

All I wanted is "World Peace."

This is a very good question by the way. I would stop diseases like Cancer, Parkinson's and MS are just a few from happening. I would also if this applies here make sure that people really know how to drive before they hit the streets with their honking and fast driving and not paying attention because they are talking on the phone from murdering others.

I would stop the pain encountered during child labour.
