Vandana Shiva advocates an approach that is based on the principle of ahimsa - meaning non-violence or harmlessness, drawing on the ethics of ecological and feminist thought that promotes diversity and pluralism in knowledge, action, nature and culture. Shiva is a world-renowned environmental thinker and activist.  In 1991, she founded Navdanya, a national movement to protect diversity and integrity of living resources. Navdanya sets up community seed banks, supports conversion to organic agriculture, and is establishing direct producer-consumer links for food security and safety. From the Series:Danz Lecture Series
