Colin Beavan, the 'No Impact Man'

In his famous book and documentary film project, "No Impact Man," Colin Beavan, a senior Dharma teacher in the Zen tradition, chronicled a year of his life as he tried to have minimal impact on the environment while living in the bustling metropolis of New York City. He followed it up with a book called, "How to Be Alive: A Guide to the Kind of Happiness that Helps the World," a sort of twist on the self-help genre that he calls "each other help."
