As of 2013, the U.S. government estimates that at any given time, approximately 27 million men, women, and children may be victims of human trafficking and within that 27 million, 18,000 people from over 50 countries are trafficked into the United States every year and over 300,000 children are trafficked within the U.S. annually. https://en.wikipedia.org/wiki/Human_trafficking A lot of the victims a are women and children. The children are used for forced labor 12 per day 7 days per week and usually receive no education. The children are also used in brothels, as child soldiers and sometimes their organs are harvested. It is estimated that human trafficking is a 32 billion dollar industry. A pimp can earn $67,000 from one girl. It is not limited to just one country or region. Some estimates say there are 60,000 slaves in the U.S. A lot of them in California and in the San Francisco Bay Area where I live. If you do a search online for "human trafficking" you will find all kinds of information. To me it is staggering. There is all kinds of injustice in this world but I believe this is one of the worst. When a child is sold into slavery they are robbed of there very soul. They become property and not a human being. There are all kinds of ways you can help. If you do a search there are a lot of organizations fighting to end human slavery. Here is a local one for me: http://www.freedomhousesf.org/ It is not enough to free people from slavery, that is just the beginning. When that happens they need a lot of help to recover from a lifetime of abuse. That is what this organization does. There are a lot of ways to help this is just one.
