Silence & John Francis

In honor of silence, I share this this TED Talk with John Francis, a personal inspiration of mine.  

In case you are unfamiliar with him, after the S.F. oil spill of 1971, where over a half-million gallons of oil polluted our waters, John Francis completely gave up motorized vehicles ('72-'94)  and walked much of the U.S. as well as South America.  

For seventeen years, he also held silence (while earning several degrees, teaching, and becoming a UN Ambassador, etc.), which he describes in this TED Talk.  

I appreciate his message, that "we are the environment."

If giving up motorized vehicles or holding silence (even for a day) is not an option for many of us, what can we do (or not do) to show our solidarity with the silenced and suffering neighbor, human and other-than-human?
