Why should we change? Most don't realize a change is required. Well not really required but less cruel otherwise. The change is how Humanity views one another. At the moment we beings see each other as rival Clans forged via our ancestors. In essence we are at War each and every single human being on the face of the planet. We do not see each other as family. But family it exactly Is All We Are. Should  family need to be cruel to one another in perpetual judgements of worth competing to the death actualizing a genocide? See world peace is simple.  It only requires peaceful people.  When the natural born children of earth care for one another in love and demonstrations of passions world peace would already be.  Change is required so why let the hate taught to us by history override those present to see the imaginary lines which divides us dissapear.
