John Francis Walks the Earth

This ted talk was a very interesting video. The man whom it was about, John Francis is an environmentalist with a quirky story. When he was younger he stopped using motor vehicles because of an oil spill he witnessed. A couple years after he stopped talking and walked across america. On his journeys he went to different school and gained his PhD in environmental studies with some gracious help. I think he is trying to spread his message that even little changes that one person makes can affect him greatly in the long run. From city hopper to UN goodwill ambassador and a renowned environmentalist John Francis changed the world and inspired many to do the same with some small changes!
