Today's youth faces an increasingly uncertain world where climate change, rapid urbanization, the economic recession and rising unemployment pose unprecedented challenges. There are 1.2 billion adolescents across the world, nine out of ten of these young people live in developing countries. Millions are denied their basic rights to quality education, health care, protection and exposed to abuse and exploitation. Recognizing the need to turn this vulnerable age into an age of opportunity, UNICEF has dedicated it flagship publication State of the World's Children 2011 to adolescents. This video highlights the importance of investing in adolescents for breaking the cycles of poverty and inequity.
