 22 Years of Walking. 17 Years of Silence

When the struggle to save oil-soaked birds and restore blackened beaches left him feeling frustrated and helpless, John Francis decided to take a more fundamental and personal stand—he stopped using all forms of motorized transportation. Soon after embarking on this quest that would span two decades and two continents, the young man took a vow of silence that endured for 17 years.
