A couple (夫妇) have travelled around the world in 297 days-without taking any planes Tom Fewins and
Lara Lockwood used 78 buses, 61 trains, 34 cars, 18 boats, six bicycles, and even one elephant. They wanted
to prove that tourists can still be well travelled without damaging the environment. They aimed to product less
than 3,000 kg of carbon dioxide (二氧化痰), compared with six times that amount if they had gone by plane.
They spent ten months travelling 44,609 miles through l8 countries on land and sea.The couple's world tour
began in June 2008 with a two-hour bus journey to London from their home in Oxfordshire. They took the
train, Eurostar, to Brussels and then caught a bus and train to Hamburg before going to Copenhagen. The
couple even rode on an elephant for l5 miles through the Chinese part of the Mekong River (湄公河).
The couple hoped to write a book based on their journey to teach other travellers how to travel without
damaging the environment.
