March 4 is observed as World Day of Fight Against Sexual Exploitation every year since 2009, to create awareness against sexual exploitation, which  overwhelmingly involves women and children. Every day many women, girls and often young boys, are trapped by international criminal networks. They exploit them sexually, traffic them and enslave them.
The UNICEF estimates that more than 3 million children worldwide are affected by prostitution.  Every year nearly million people are sexually exploited. It includes not only women and girl children, but also young boys and young men.
Human Trafficking is now a highly lucrative multi-billion dollar business. In a shocking BBC report, every year more than 2.5 Lakh people travel abroad for SEX TOURISM for the purpose of having sex with young children. This money making business has increased the child prostitution all over the world.
