UNICEF and Goodwill Ambassador David Beckham are bringing the voices of children to those with the power to change our future.

A unique installation harnesses mobile technology and social media to deliver messages from children and young people across the globe directly to world leaders at the United Nations General Assembly. The messages highlight challenges they face in their homes and communities - including extreme poverty, inequality, violence, deadly disease and conflict - and express their hopes for the future.

You can be a part of this, too. Share your views and hopes for children at http://uni.cf/youthassembly and your voice will be added to the installation, reminding world leaders to put children at the heart of the new Global Goals.
