As proof of the ability to communicate from anywhere in the world to the world wide web, you and your students may be interested in following the exploits of Ray Zahab: ultra-marathoner. He was the first to run across the Sahara and is now poised to run an unimaginable event in "South Pole Quest".
This former smoker has founded "Impossible 2 Possible" where Ray and his team take on adventures to inspire young people to "protect this fragile planet and its people". His interview on "The Hour" with George Stroumboulopoulos gives great background on the story.
