(On how travelling doesn't have to have a devastating effect on the environment)
Michael: My own trip around the globe was all flightless. People should get a bit more adventurous about how they travel and use the local public transport. Obviously if you're going to the Far East or Australia you're not going to be able to take the train, you're going to have to fly. But when you get there don't take short flights, take a train or coach.
