A few archived recommendations:
"Planting the future with Wangari Maathai" examines the journey of one Kenyan female diplomat and her fight to empower the lower class through holistic, ecological means.

"Children and God" a provocative investigation of the spiritual messages that children communicate when they are uninhibited by conventionality. Interview includes Robert Coles a child psychologist that I think is brilliant.

and...
"Jean Vanier: The Wisdom of Tenderness" interviews the Catholic founder of the L'Arche communities for individuals with disabilities with the intent to share life and learn from one another. (I was really touched by this one, particularly because of my work this year.)
