John Francis, often referred to as the "Planetwalker," is an environmentalist, educator, and author known for his profound commitment to environmental awareness and peaceful activism. He embarked on a silent protest lasting 17 years, during which he voluntarily abstained from using motorized vehicles and speaking. This radical act began in 1971 after witnessing the devastating impact of oil spills in California. Initially, his protest focused solely on transportation, choosing to walk everywhere instead of relying on cars or buses. He then decided to extend his commitment by taking a vow of silence, believing it would allow him to listen more intently to others and the environment.

During his 17 years of silence, Francis earned a B.A. in Environmental Studies from Southern Oregon University, an M.S. in Environmental Studies from the University of Montana, and a Ph.D. in Land Resources from the University of WisconsinMadison. He completed these degrees by communicating through writing and sign language, demonstrating an unwavering dedication to his education and environmental understanding. His doctoral dissertation focused on the impact of oil spills on the environment.

After ending his silence in 1990, Francis began speaking again, sharing his experiences and advocating for environmental responsibility. He worked for the U.S. Coast Guard, assisting in the development of oil spill regulations and policies. He has also traveled extensively, sharing his story and promoting the importance of listening, sustainability, and peaceful action. Francis has authored several books, including "Planetwalker: 17 Years of Silence, 22 Years of Walking," which chronicles his extraordinary journey and offers insights into his philosophy. His life serves as an inspiring example of the power of individual action and the importance of environmental stewardship.
