Malala Yousafzai is an amazing teen activist campaigning for the rights of girls and women to receive education who was shot in the head by the Taliban on her way home from school and recently nominated for a Nobel Peace Prize.
Mother Teresa (baptized August 27, 1910, in Skopje, Macedonia) taught in India for 17 years before she experienced her 1946 "call within a call" to devote herself to caring for the sick and poor. Her order established a hospice; centers for the blind, aged, and disabled; and a leper colony. She was summoned to Rome in 1968, and in 1979 received the Nobel Peace Prize for her humanitarian work.
My attitude to peace is rather based on the Burmese definition of peace - it really means removing all the negative factors that destroy peace in this world. So peace does not mean just putting an end to violence or to war, but to all other factors that threaten peace, such as discrimination, such as inequality, poverty. Aung San Suu Kyi
