While New York-based Howell will spend this month in South Africa shadowing a wild dog conservation initiative, Khanna will be pursuing her personal mission to tell the stories of India’s abused and ostracized widows. A world away in New Zealand, Hedley has devoted time to studying ethical and sustainable agriculture.
