How often do you use your car? Can you use your car less often? Do you know the following facts in the UK? ? About 50% of all car journeys are just for fun. ? Over 80% people go to work by car. ? 25% car journeys are under two miles. ? 70% car journeys are under five miles. WALKING & CYCLING Instead of using the car for short journeys, why not walk or ride a bicycle? Walking is a most popular form of exercise—it’s healthy and it can save you money. If you work nearby, try walking or cycling instead of driving. BUSES Bus companies are using new buses: some run on new fuels which produce less pollution; some have easier access for disabled and old people. There are special traffic lanes (行车道) to make bus journeys easier and more reliable. So do something to help solve the pollution problem—let the bus take you to work and your children to school. TRAINS All car journeys, long or short, can be hard work. For some trips it is wiser to take the train. Leave your car at home and walk, cycle or take a bus to and from the station.
