The increasing public problems related to climate change and the economic and political transformations of the 21st century demand more democracy. New worldwide problems demand new institutional solutions. The United Nations needs to recognize that being an exclusive club of governments and involving some representatives of civil society is not enough to connect citizens with the international decision-making system. The political pluralism of the world's societies is not represented at the United Nations. International political decisions have to be informed by all perspectives. Governments have their own self-serving interests and this is especially true for authoritarian and totalitarian regimes. The United Nations need to make a step forward in the quality of plural representation that makes minorities seen and heard. This is the main reason why it is necessary to support the creation of a United Nations Parliamentary Assembly.
