Today, nearly 215 million children work in the world, many of them full time. These children do not attend school and have no time to play. Many do not receive proper care and feeding. They are denied the opportunity to be children. More than half of these children are exposed to the worst forms of child labor such as work in hazardous environments, slavery, and other forms of forced labor, illicit activities including drug trafficking and prostitution and involuntary participation in armed conflict .
