Just a snippet for those who are not interested in going through the whole article
"Slavery was the first human rights issue to arouse wide international concern. Yet, in the face of universal condemnation, slavery-like practices remain a grave and persistent problem in the closing years of the twentieth century.
The word "slavery" today covers a variety of human rights violations. In addition to traditional slavery and the slave trade, these abuses include the sale of children, child prostitution, child pornography, the exploitation of child labour, the sexual mutilation of female children, the use of children in armed conflicts, debt bondage, the traffic in persons and in the sale of human organs, the exploitation of prostitution, and certain practices under apartheid and colonial régimes. "
