Ban Ki-moon hails achievements of millennium development goals but warns world still riven by inequalityThe millennium development goals (MDGs) have driven “the most successful anti-poverty movement in history” and brought more than a billion people out of extreme penury, but their achievements have been mixed and the world remains deeply riven by inequality, the UN’s final report on the goals has concluded.Ban Ki-moon, the UN secretary general, said that while the 15-year push to meet the eight goals – on poverty, education, gender equality, child mortality, maternal health, disease, the environment and global partnership – had yielded some astonishing results, it had left too many people behind.
