Brooklyn-based photographer and cinematographer Jeremy Snell has created a documentary of the life of young "fisherboys," who are forced to work on fishing boats on Lake Volta in Ghana.
San Francisco-based photographer Lisa Kristine has spent the past 28 years documenting indigenous cultures in 70 countries on 6 continents around the world. More recently, she has been working with the organization Free the Slaves, using her photography to document the monstrosity that is modern day slavery.
The video above is a powerfully moving talk Kristine recently gave at TEDxMaui about the subject and her photography that is meant to make a difference.
