World Peace
Alright, this is not a tech entry, but the entire world seems to want peace. Now pay attention while I give a simple remedy for World Peace. Here it is. The world needs one ruler and it will have peace. I'm not saying who that ruler should be, but having one person in charge is the only way we will have peace. There you go, that is my simple take on the whole "World Peace" thing. For us to be one, we have to merge together under one ruler and then a united world can have peace.
