A 15-year effort to implement eight goals adopted by world leaders at the start of the new millennium has helped lift more than one billion people out of extreme poverty, enabled more girls to go to school than ever before, and brought unprecedented results in fighting diseases such as HIV/AIDS, the U.N. chief said Monday. In the final report on the Millennium Development Goals released Monday, Secretary-General Ban Ki-moon said the global mobilization to implement the goals by the end of 2015 has produced “the most successful anti-poverty movement in history.”
