What are the pros and cons of human trafficking from a European point of view?

There are no pro's of human trafficking. I'm currently trying to do a research paper on the same topic and there is none. There are some websites that are sick and say the pros are that you get sex, they are pretty, etc. But there could be a pro to this... that once rescued they are helped to starting a new life. I hope this helps, it didn't help me any.
