Transport provides a key component for our economic and social activities, enabling us to shift resources and products, and allowing us to make journeys for leisure and work. Most forms of transport, including cars, buses and aeroplanes are powered using fossil fuels and contribute to air pollution, particularly in urban areas where there is a lot of road congestion. In addition to this, transport pollution can contribute to acid rain and climate change. As the number of cars on the road increase, the development of new roads is required to reduce congestion. In many cases, natural environments are destroyed or adversely effected as a result. Many governments including the UKs try to encourage people to use public transport, bicycles and car share initiatives to reduce the amount of traffic on the roads. This is achieved by imposing taxes on car users, whilst providing good public transport.
