Climate change is igniting a rise in human trafficking, as natural disasters put women and children in post-catastrophe situations that traffickers exploit.

The Renew Foundation is helping bar girls and sex workers transition out of dependency and into new careers and new lives. Photo credit: Hannah Reyes Morales
