How Do Years Of Silence Change Someone?

Part 1 of the TED Radio Hour episode Quiet. Listen to second part of this story here.

About John Francis's TED Talk

For almost three decades, John Francis has been a planetwalker, traveling the globe by foot and sail with a silent message of environmental respect and responsibility. For 17 of those years he didn't speak a word.

About John Francis

One day in 1983, John Francis stepped out on a walk. For the next 22 years, he trekked and sailed around North and South America, carrying a message of respect for the Earth — for 17 of those years, without speaking. During his monumental, silent trek, he earned an MA in environmental studies and a Ph.D. in land resources.

Today his Planetwalk foundation consults on sustainable development and works with educational groups to teach kids about the environment.
