What do 1.2 billion young people think about a world whose leadership they are about to inherit? To find out, the UN Chronicle invited young persons between twelve and twenty-four years old from around the globe to take over its pages for this special Youth Issue. Read their opinions, concerns and suggestions on nuclear disarmament, on protecting child soldiers, on social media and the digital divide, adolescent marriage and sexuality, rights of indigenous communities, and more. The Youth Issue also features exclusive essays written by the UN Chronicle's Facebook audience on the Millennium Development Goals.
