Green activism is often largely a scientific and political affair. But it doesn't need to be that way. Some of the best-known environmental organizations in the U.S. began with religious or spiritual roots: According to its website, Greenpeace was founded in a church basement by activists inspired by the Quaker tradition of "bearing witness."
