On October 6, 2007, British adventurer Jason Lewis crossed the prime meridian in Greenwich, England, completing the first human-powered circumnavigation of the globe. Human-powered navigation does not rely on the use of devices such as motors or sails.
 
Some of the methods used by Lewis to traverse the globe included hiking, biking, roller blading, kayaking, and pedaling a paddleboat called Moksha. It took Lewis about 13 years to complete the journey.
 
Lewis is a supporter of sustainable development, and took the opportunity to talk to students all over the world on his journey, which he called Expedition 360. He visited more than 900 schools in 37 countries.
