Olympics and the world

Hi, hello. A while ago I had a post that was titled the exact same thing but for some strange reason I deleted it. So this is the new one about the same thing. The theme song of the 2010 Olympic Winter games was "I Believe", it talks about in the song of a world brought together as one. I have thought about this and its so true. Could you imagine if like how the world gets together for a sporting event like the Olympics. We stand united while we compete against each other. The original purpose of the Olympic games was to stop war for a bit and have a while of peace in the midst of turmoil. What if rather than fighting against each other the world united and we fought against things like poverty, disease, famine? We could make our home a better place. It could be incredible. If we can join together and have peace for two weeks for a sporting event why is it so hard to be at peace with each other all the time?
