Never doubt that a small group of thoughtful, committed citizens can change the world.” That quote attributed to the late American Anthropologist Margaret Mead has inspired countless activists. That included a small but dedicated group of men and women who began a pilgrimage from Washington State to the Middle East in 1982. They walked 6700 miles! More than forty years later, their experience offers important guidance to activists seeking positive change today. In this episode of Challenge 2.0, we meet ‘the atomic pilgrim’, who shares his experience, wisdom and guidance.
