Why is food insecurity so common in Kern County, and what can people do to solve it? Those two questions are at the core of a new documentary called "INVISIBLE: The Unseen Faces of Hunger." The film was produced by members of Transitional Youth Mobilizing for Change, also known as TYM4Change, a nonprofit that creates opportunities for young people to address issues in their community. Valley Edition Host Kathleen Schock spoke with its executive director, Dixie King, along with two of the young filmmakers, Nicholas Hulsey and R. Amaya.
