Wangari Maathai, founder of the tree-planting and women's-empowerment Green Belt Movement , and the first African woman to win the Nobel Peace Prize (2004), died this Sunday night. I took this photo at a May 2005 tree-planting ceremony on the north lawn of UN headquarters in New York, along with lots of other pictures . It was the only time I really had a chance to talk to Dr. Maathai, although I would see her again in Nairobi a year and a half later at the launch of UNEP's "Plant for the Planet: Billion Tree Campaign."
