Last week, the FBI announced nationwide child-sex-trafficking raids, with a disproportionately large number of the arrests happening in Seattle. On Monday, a coalition of Catholic sisters will launch an anti-trafficking bus advertising campaign. Stop the Demand looks to make people aware of the extent of human trafficking–it’s the world’s second biggest criminal industry and one for which Washington state, with I-5, ports, and agriculture, is a hotbed–as well as the connection between consumer demand for cheap goods and trafficking. “We are asking the question, ‘Why are we allowing people to be trafficked, either for sex or so we can have cheap products?'” says organizer Sister Susan Francois. Of course, knowing whether the products we buy benefited from slave labor somewhere along the supply chain is a tall order, as is educating people on that connection via bus ads. The campaign will be officially launched at 3rd and Pine at 2:30 PM on Monday, one day after the United Nations’ International Women’s Day.
