Prostitution law
However, sex worker activists and organizations distinguish between human trafficking and legitimate sex work, and assert the importance of recognizing that trafficking is not synonymous with sex work. The Sex Workers Alliance Ireland organization explains: "victims of human trafficking may be forced to work in industries such as agriculture, domestic service as well as the sex industry. It is critical to distinguish human trafficking, which is a violation of human rights, from voluntary migration." The Open Society Foundations organization states: "sex work is done by consenting adults, where the act of selling or buying sexual services is not a violation of human rights. In fact, sex workers are natural allies in the fight against trafficking. The UNAIDS Guidance Note on HIV and Sex Work recognizes that sex worker organizations are best positioned to refer people who are victims of trafficking to appropriate services."
Human trafficking
Abolitionists who seek an end to sex trafficking explain the nature of sex trafficking as an economic supply and demand model. In this model, male demand for prostitutes leads to a market of sex work, which, in turn, fosters sex trafficking, the illegal trade and coercion of people into sex work, and pimps and traffickers become 'distributors' who supply people to be sexually exploited. The demand for sex trafficking can also be facilitated by some pimps' and traffickers' desire for women whom they can exploit as workers because they do not require wages, safe working circumstances, and agency in choosing customers.
