You are citizens of this global community, where each and every one of you has to work together, try to resolve all of these issues which are interconnected. Try to have broader, comprehensive views; try to develop your capacity... be a proud global citizen." Secretary General Ban Ki-moon, 21 April, 2011Credit: UN Photo 470637
