It's unfortunate that we are a tribal specie. We excel at inventing distinctions to divide ourselves. Religion, race, ideology, north, south, old young - we are great at creating new reasons to hate and kill each other. We have developed in one respect...we are really very effective at killing large numbers very quickly. As our numbers increase and our demands for energy, fresh water and habitable land pit one tribe against another the killing business will be a growth industry. Maybe we should think of it as culling the herd.
