At one time in history has there been such a mass movement of people from the country side to the city as is happening now. By the year 2030, it's estimated that more than two thirds of the world's population will be living in cities, twice as many as today. This means that the problems faced by cities today —overcrowding, poor housing, unemployment, poverty and lack of food and water — will be twice bad, unless we find solutions soon.
Another serious issue is how to provide good transportation for the citizens. Many of the world's major cities are already struggling with out-of-date transport infrastructure(基本设施). How can they deal with the additional demands?
London is a good example. Its enlargement was made possible by the invention of the steam engine, which powered the world's first underground railway. But its transport systems are now hopelessly out-of-date and need urgent modernization. London's future success depends very much on developing better public transport.
Over a million people travel into central London every day from outside the city. They, and the people who live in London, want a public transport system that is efficient, safe and environmentally friendly. What they often get, however, falls far short of that ideal. Commuters complain about cost and pollution, while businesses worry about the problems their staff have in getting to work on time. Yet, the proportion of London households that own a car grew from just over 10 percent in the early 1950s to over 60 percent today.
As the city has become increasingly crowded and polluted, there has been a growing realization that action must be taken soon.
