Human trafficking is a $32 billion industry that affects over 27 million victims worldwide each year. Victims are typically recruited through false promises, transported across borders while having their passports taken, and sold into situations of abuse and rights violations. The recruitment, transportation, and arrival of victims establishes a chain that maintains control over vulnerable people. Poverty, discrimination, and social exclusion are among the root causes that make people susceptible to trafficking. The UN works to prevent trafficking through initiatives and protocols that protect victims and promote international cooperation.
