Is Urbanisation Positive Or Negative Environmental Sciences Essay

Is urbanisation Positive Or Negative Environmental Sciences EssayUrban populations fork up greatly increased. Just recently, it exceeds the rural population around the reality. There ar some advantages and disadvantages of urbanization. This essay, will discuss its dogmatic effects and negative effects of urbanization.Urbanization is good and desirable. It goes hand in hand with economic ontogenesis (Debroy, 2009). People move into cities to get a better employment. In rural compasss, bulk usually have small family farms, just it is difficult to improve ones living standard. Farm living depends on unpredictable environmental conditions. If it comes up against a drought or flood, the life will become very difficult. So people living on a farm might wish to take their chance by pitiful to the city and trying to make enough money to send back home to their struggling family. That is why to a greater extent and more people move to cities. The development of social economy is the d riving force of urbanization, turn the economic globalization further accelerated urbanization.Urbanization affects many atomic moment 18as. At first lets discuss the family between urbanization and population. U.S. Population Research Institute showThere are about half(prenominal) of the current global population lives in cities. By 2050 this proportion will increase to two-thirds, which would bring more pressure to the citys infrastructure and resources. In 1900, 10 of the worlds most populated cities were in North America and Europe, still in the 20th century, in the top ten cities, only Tokyo, New York and Los Angeles were the cities in developed countries. however developing countries can not provide appropriate living conditions for so many urban residents. At present, there are about 25 to 30 percent of the population all all over the world lives in inadequate accommodate facilities, or lack of water in and sewage treatment facilities streets (Chen, 2009).Urban slums are places where not only diarrhea, typhoid, gastroenteritis and other water-related diseases but also the breeding ground for sexually transmitted diseases such as AIDS. So the uncontrolled increase population is one of the biggest problems of urbanization. The presidential term take to resolve it.Urbanization has a huge impact on the environment. The large-scale urban constructions change the pi forget me drug natural environment, and ca use up great changes for the original ecological environment.It also changed the original nature of the cardinal surface. The changes of underlying surface cause the urban heat island effect. Urban construction destroys the original river system. Urbanization changes the way we use the land, and changes the original agricultural land into building land and formed a city function area (The effects of urbanization, 2008).So the urban landscape replaces the original rural landscape. Urbanization also influences the forms of employment of residen ts, regional industrial activities and non-agricultural activities become the main running(a) style in the cities.Generally, the advantages of urbanization can be listed as follows. First, urbanization makes our life easier and more convenient, and it has promoted communication among people. Second, urbanization can quicken our pace of living and working style to catch up with the developed countries-as we all know that the developed countries are all high up urbanized. Third, when more and more people flood into cities, the city is often becoming bigger and bigger and urban development is experiencing a new round of leaping forward. Fourth, urbanization can bring a lot of job opportunities for the people who are out of work.Urbanization is often viewed as a negative trend, but in fact, it occurs naturally from individual and corporate efforts to stifle expense in commuting and transportation small-arm improving opportunities for jobs, education, housing, and transportation. Liv ing in cities permits individuals and families to take advantage of the opportunities of proximity, diversity, and marketplace competition (The effects of urbanization, 2008).However, the disadvantages of urbanization are also obvious. To begin with, the city contamination, especially industrial three depopulatesso called air pollution, water pollution and solid waste pollution, damages the environment and ecology of peri-urban area. Air pollution, water pollution, and solid waste pollution decrease the quality of the urban environment and endanger peoples health. The changes of underlying surface cause the urban heat island effect. The urban heat island effect has become a growing concern problem over the years. Additional city heat is given off by vehicles and factories, as well as industrial and domestic heating and cooling units. This effect causes the city to become 1 to 6 warmer than meet landscapes. The effect also reduces the water in soil and increase carbon dioxide emis sions (The effects of urbanization, 2008).Traffic and factory whitethorn cause noise pollution, which affects peoples rest, work and communication, and even affects their health. Traffic congestion and poor housing conditions are other problems in cities. Traffic congestion is leading to serious wastes of time and energy. Meanwhile lack of housing and its poor quality affect the quality of urban environment. Rapid growth of the urban population may cause the problem of unemployment. It is imbalance in development between Urban and rural. A large number of landless farmers on resettlement are the biggest problem of government departments. Moreover, more problems, such as change magnitude crime rate, over-crowding, might increase, since more people are concentrated in a relatively smaller place.But the problems above can be solved by government. First, the government should order the factory to reduce emissions. Then advises people do the garbage recycling. Second, the government s hould plant more trees in the city. Third, develops public transports. Finally, the government needs to control the population increase and improves peoples living standards.It is obvious that the advantages outweigh the disadvantages. Urbanization is an inevitable harvest-time of social development. High urbanized growth is the mark of developed countries. The process of urbanization is same as the process of human development. Although in this process we will meet many problems, we should try to solve it. So our city will have a better future.
