ABC News' Martha Raddatz recently joined Dr. David Warner, a public health expert from San Diego, Calif., who has done humanitarian work in Afghanistan since 2004, on a visit to the village of Jalalabad. Warner, along with other dedicated volunteers, works with the local communities to get much needed supplies, like pens, notebooks and Internet to schools and medical supplies to hospitals.
At one school in Jalalabad, there are too many children to fit in the classroom, so the school moved the desks to the roof. At last count, 3,200 children attend the La Jolla Golden Triangle Rotary Club High School, named after the rotary club in La Jolla, San Diego. Warner became involved in his humanitarian work through the city, which teamed up with the school in an effort to promote peace. (Courtesy Dave Warner )
