"Sovereign nation states have conspicuously failed to cooperate well enough to deal with increasingly global problems such as climate change, environmental degradation, and organized crime, Barber said. Nations focus on their borders, which are seen as competitive zero-sum games. “But if we shift our gaze, in thinking about global governance, from nation states to cities, things suddenly become possible that seemed impossible. Cities are apart from one another, separated by wide spaces. Their relationships are based on communication, trade, transportation, and culture. They are relational, not in a zero-sum game with one another.”" - klemo from Bookmarklet
