Prefer to implement them? Anyone with a human heart would like to see all trafficking stopped. Period. At this point there are limited resources and options. The goal is to save as many people as possible.
The best way to do this is to identify why people are being exploited (Lack of economic options, social attitudes) or which can be reached (forced prostitutes, child slave labor) and address that. In countries where social attitudes contribute to trafficking, outside help is incredibly difficult to offer and at best helps only the tiny percentage who can ask for help. In countries where economic necessity contributes, there are a few, limited, largely ineffectual options. Name brand distributors and industries have taken some smalls steps to better the lives of workers when public outrage has affected the bottom line. Organizations which offer education have made a difference for a few.
Overall, it is a far-reaching problem with no immediate solution. None of the strategies currently implemented have done very much. A few things have proven to work on a small scale. One of those is improving the lives of girls through education and investment which has been shown to work in both patriarchal and impoverished areas.
The trafficking of human beings is not a feminist issue. Some feminists prefer to focus on the plight of women in these countries because feminism is humanism with a focus on women. Focusing on aspect of a huge problem does not mean that you don't care about the rest. It only means that with a problem this large, it is impossible to focus on all aspects all the time while still being effective.
