Just over ten years ago, Germans tore down a wall that divided their country and the whole of Europe. Stepping through the hole in the Berlin Wall, they took the first steps towards the reunification of West and East Germany and the end of the Cold War. Today another wall is being torn down - that between purely domestic law and international law. Companies are engaged in international trade at ever increasing rates. Environmental degradation has proved to be a global problem that cannot be solved with uncoordinated local measures. Individuals worldwide are pressing their governments for the recognition of a common set of human rights.
