The United Nations has been taking a bit of a beating over recent years. Some feel it is too bureaucratic, others feel it has outlived its utility, but I believe that even with the challenges it faces, the UN has come to symbolize the ideals for a fair and just world. It's not easy being an organization which has a membership of 6 billion!
the Universal Declaration of Human Rights (and the accompanying 30 articles) is well worth a read, giving us a reminder that each human is unique, "valid", and deserving of respect. http://www.hrweb.org/legal/udhr.html
