There is a fantastic photo essay on the UNICEF site entitled Silence is Acceptance. It has a really powerful message to tell about the proliferation of child sexual exploitation worldwide and is accompanied by photographs and personal stories of a number of victims and survivors.
UNICEF does a number of thought provoking photo essays and other titles include: Building a world fit for children, The rights of the child - Part I and The rights of the child - Part II. Their site is certainly worth a visit; in fact, the “rights of the child” photo essays gave me goosebumps over every single part of my body. It is a chilling and poignant reminder of how precarious the state of our world’s children that we had to codify and implement such a rights charter.
