The history of the human race is a violent one. It is a story of destruction and hate, bloodshed and suffering. Despite all this, in defiance of all our flaws we now have the opportunity to change, to grow, to better ourselves. Our world has become smaller, more interconnected. We depend on one another more now than we ever have in history. Nations, which are nothing more than an extension of primitive tribalism, must come to an end. It's ironic when we see aboriginal tribes in the Amazonian rainforests or in sub-Saharan Africa and mock them for their warlike and savage ways because we behave similarly, only on a much more sophisticated and reckless scale.
