Urbanization and City Infrastructure Urbanization is defined as the increase in a city’s population over time and can occur due to a variety of factors including the natural expansion of a city’s population, the conversion of a rural area to an urban one, or the migration to urban areas by those who previously inhabited rural environments. ■(A) Urbanization is an ever-increasing trend; one that can be observed in areas throughout the world as economies begin to rely more on manufacturing and business for revenue. ■(B) Working and living in large cities is gradually replacing the traditional rural careers such as small-scale agriculture. ■(C) It is estimated that within the next century, more than half of the world’s citizens will reside in cities. ■(D) While some cities are planned, most cities are organic, meaning that urbanization in these areas takes place with little or no advanced planning. While the increase in urban areas and its population has yielded positive effects such as an increased concentration of businesses and more career opportunities, researchers have also discovered a host of detrimental effects on the areas in transformation from rural areas to urban centers. The concerns about urbanized areas worldwide differ somewhat in their relative importance, but many cite traffic congestion, inadequate public transportation, insufficient waste disposal facilities, inadequate solid waste collection, and a lack of water and sewage treatment facilities as primary concerns. One hundred years ago in Australia, the commute from Paramatta to the center of Sydney took approximately an hour by horse and cart. Today, the same trip in a car takes longer. Opponents of unplanned urbanization have also pointed out the destruction of agricultural land and animal habitat as a negative consequence of urbanization. Many of these problems could be eliminated, or at least mitigated, through the construction and maintenance of appropriate city infrastructure. Although the term is somewhat ambiguous, it was traditionally understood to mean roads and sewers. However, the U.S. National Research Council opted to widen the definition of public works infrastructure to refer to roads, bridges, mass transit systems, and water and waste management systems. Chief among the concerns of city dwellers is the issue of traffic jams and general congestion, and the corresponding difficulty in navigating the streets of any large urban area. Appropriate infrastructure, however, could serve as a useful tool in curtailing this problem. Two factors that exacerbate traffic congestion in a typical city are narrow streets and a lack of off-road parking, which would force many workers to park on the side of the road. Several solutions to the excessive traffic in urban areas have been proposed. Firstly, the construction of bypasses would eliminate the amount of traffic in the downtown areas, as travelers could use faster, more direct routes to arrive at their destination. Parking concerns could be addressed by constructing parking garages consisting of several stories. In this way, many cars could be stored in a relatively small amount of space. Closely related to the previous problem is the issue of inadequate public transportation. People will choose to ride buses; however, the system must be efficient and reliable. The establishment of a variety of mass transit systems such as subways, buses, and ferries could provide a feasible alternative to those that use their own vehicles to travel to their jobs in the city. Many cities have concerns about the problems involving waste collection and disposal. Along with education about waste diversion techniques such as composting and recycling, the development of city infrastructure can play a key role in ensuring adequate waste treatment. This would include the construction of easily accessible recycling facilities and appropriately placed composting facilities. In addition, urban areas should ensure there is a citywide transit system in place to collect solid waste. Finally, citizens in many urban areas have concerns regarding sewage treatment plants and water treatment facilities. The development of such facilities in an acceptable area, typically in a location outside of the city, could effectively deal with these concerns. Not only would this infrastructure improve the health of the citizens, but it would also benefit the environment by reducing the amount of pollution in the form of sewage entering water sources. The word "detrimental" in the passage is closest in meaning to
Passage Three Within fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything that goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else. The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well. Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: first, it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that grounders and rollers break up everything that can be broken. Finally the rubbish will pass under magnets, which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the final stage. The first full scale giant recycling plants are, perhaps, fifteen years away. Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will-be forced to build their own recycling plants before long. Which of the following statements is TRUE
In its plans to develop Greece as a year-round tourist destination, the Ministry of Tourism is focusing on alternative forms of tourism, beyond the sun, sea and sand classical summer holiday. Among other sectors, these include health and beauty tourism. Apart from stunning natural beauties, nature has endowed Greece with hot springs whose therapeutic properties were already known in ancient times. Hippocrates, the father of medicine, was the first to discover their virtues some 25 centuries ago. The geographical location of these springs is not accidental as it is related either to tectonic events or volcanic activities. Their waters are therapeutic for ailments such as rheumatism, arthritis and complaints related to lungs, kidneys, blood circulation and dermatology, among others. Of more than 750 natural springs, around 80 operate professionally as natural spas, many with accommodation and other facilities. In consultations with tourism associations, hoteliers and tourism investment consultants, the government is drafting a new law to define the rules for health tourism. Expected to be approved by Parliament early next year, the law will establish the legal framework and the prerequisites for health tourism centers, including provisions for handicapped guests. One condition will be that such centers will have to operate all year, not just in summer. Another is that hotels providing health facilities should be near a hospital or an airport. The Development Law, which came into force in December 2004, provides attractive incentives, such as subsidies or tax breaks for health tourism center investments. The government is encouraging regional development in areas in northwestern Greece. Doctors and investors from Sweden, Britain and Germany have already shown interest in establishing health tourism centers in Greece, to take advantage of the country’s mild climate, low humidity and year-round sunshine. In addition to hydrotherapy, some centers will deal with illnesses of the psyche — depression, psychological problems and addictions. The serenity of many parts of Greece’s countryside is seen as therapeutic for people from northern countries where cold, dreary climates can lead sufferers to depression and suicide. Spread throughout Greece, many natural mineral springs are owned by the National Tourism Organization of Greece and managed by the Tourism Development Co. The latter is gradually divesting itself of its. large and diverse portfolio through long-term leasing of its holdings, including mineral springs and spas.
