'Effects of Overpopulation in China Essay\r'

'This lit review discusses the impacts of over tribe on the surround in china through four briny studies. a persona line of business directed its look on one consequence: the weewee system stretch out and the aquatic ecosystem, the over expend of bring and resources as well as the defunctness of green let down, mood change, GHG emission and desertification of k zero(prenominal)k down1. several(prenominal)(prenominal) methods and sources were apply such as drag†res publica†resolution (PSR), urban-rural race posture or separate look cover scripted previously2. The results of these studies clearly show that the over mountain has seven-fold negative impacts on the Chinese milieu and that strategies and policies regarding these issues should be established.\r\nThe population of main republic China is developing exponenti every(prenominal)y and it is a serious issue because of its impact on the surroundings. The body of peeing inadequateness is suppur ation and as it is presented, the expectations of the Chinese people exceed the capacity of the land3. Since the population of China is increasing fast, the urbanization of land and the unpolished development increment at the aforesaid(prenominal) rhythm4.\r\nAs it is presented, homosexual activity and human slow-wittedness ar the main description for humor change5. According to Shijie Wang’s issue, the south-west of China is experiencing a desertification, in other words the land becomes like a desert left with no resources6. each(prenominal) article presents a different look of conducting its research to prove its point. In Qian Hong et al. research, the methods used to pursue the study ar forceâ€Stateâ€Response (PSR), the landscape ecology method and Remote Sensing †spheric Positioning System (RS-GPS) 7. According to the authors, on that point are three types of indicators: Pressure indicators, State indicators and Response indicators7.\r\nThe indicators either presented a luxuriously or a low payoff. If the shape is high, it means that the orbit suffered from primal water degradation; if the number is low, it means the opposite7. The depth psychology of the research is made through a figure out called Analytical hierarchy process (AHP) that has four specific indicators7. Jianfa Shen’s study uses urban-rural population model to do predictions around the density of the population and is also represented as spatial demographic-economic model 8, whereas Shijie Wang conducted its research by intrustigating the studied area and by using indicators such as aerial photos and satellite images. He therefore compares and analyses the results with previous images and researches from the land\r\n9. The only piece of work that did not use whatever kind of Research method was written by Hung Ming-Te et al. who preferred to compose the newspaper in reference to researches and studies made and scientific predictions 10. One of the just about all important(predicate) consequences of overpopulation is the expanding inadequacy in water resources. Investigators processed in six districts of China which are leave-taking of one region (Jinan) that was recognized for its important source of water, aquatic ecosystem and surface. Due to industrial development and human actions the water hold became polluted and rarer\r\n11. Researchers found that water insufficiency and erosion, rainy climate, worthless people land vegetation, climate change, loss and decrease of coarse drudgery, which all lead to desertification of land, are all consequences of the activities of the overpopulation 12. Ming-Te et al.’s study presented that the GHG level increased rapidly and the national security is at risk. GHG growing production would also come across the drop of water and air befoulment worsened than it actually is; also they stated that climate change, in addition to being caused by overpopulati on, is influenced by poor sustainable development, poor resources management and over-use of energy.\r\nThis study shows that such changes fill impact such as poor water resource and low agricultural production. These consequences engender other concerns such as the lack of food, the decrease in water resources and the desertification of land 13. The conclusions are clear regarding this area, the colossal use of natural resources is a holy terror for the environment’s protection and preservation 14. Hong et al. are from the same opinion when they wrote that water condition is getting worse and it affects China’s population’s modus vivendi as well as the aquatic ecosystem 15.\r\n10 Hung Ming-Te et al., 363-366\r\n11 Qian Hong et al., 321\r\n12 Shijie Wang et al., 127-129\r\n13 Hung Ming-Te et al., 363-364\r\n14 Jianfa Shen, 39\r\n15 Qian Hong et al., 319\r\nIn the field of environment, every single constituent is closely related to another one. Each of the fo ur studies shows how the desertification of land, the migration, the exceeding use of resources and the pauperization of population are linked. In Wang et al.’s research, poverty is shown to be one of the most devastating causes of desertification because farmers, in order to outlast and feed their families, have to increase the production of grains. The overexploitation of the land then leads the land to become rocky 16. According to Shen’s study, factory farm is over-used and China has to import grains to extend to the population’s needs\r\n17. The harm of the environment and the growth of the land desertification are strongly correlated with the increasing population of this region as well as their activities 18. In reference to Wang et al., Shen and Ming-Te et al.’s studies, since the land is experiencing a phenomenon of desertification because of the exceeding use of agriculture and the high density of population in rural zones, populations are migrating to cities that have already exceeded their capacity in supporting people19. Basically, what Shen is difficult to explain is that the construction of urban areas and the overexploitation of lands lead to a decreasing number of green land which causes the environment to deteriorate, because the more(prenominal) people there is, the more resources needful 20. The biggest problem China is facing is the lack of policing and measures adopted regarding the protection of the environment. According to Ming-Te et al.,\r\n16 Shijie Wang et al., 131\r\n17 Jianfa Shen, 36\r\n18 Shijie Wang et al., 124\r\n19 Shijie Wang et al., 124-131; Jianfa Shen, 36-39; Hung Ming-Te et al., 363-364 20 Jianfa Shen, 35-36 China’s way of life of ‘fighting’ against climate change is to invest in the development of sustainable technologies as well as establishing measures and policies regarding the environment 21. Qian Hong et al. undertake that the saving and the protection of w ater are essential to the survival of the land and aquatic ecosystem 22. The researchers from the two other articles did not write about the policies that should be established to extend the environment.\r\nStudies show that the impacts of overpopulation are multiple and they do affect the ecosystem in China. Shijie Wang et al.’s study proved that the land is overloaded with population growth and has met its capacity. This forced farmers to deforest the land of the Liupanshui district in order for them to increase agricultural production. Also, even though the environment is favorable in this region for such phenomenon to happen, restricted natural resources, overpopulation activities, rapid population growth and social instability make the process happen faster. The consequence of overpopulation’s production of sulfur dioxide in the ambiance exceeds the national average for smelting sulfur by over 13.8 times in some regions such as Bijie and Zunyi which causes air p ollution and desertification of land 23.\r\nThe results of the study conducted in the region of Jinan by Qian Hong et al. clearly showed that this region has the opera hat water condition because of its good conservation of environment, poor population density and important vegetation 24. Hung Ming-Te et al. proved that overpopulation, causing in many ways the change in climate would increase the frequency and cogency of natural weather disasters 25. Jianfa Shen suggested that the exceeding use of natural resources due to the increasing density of population is a threat for the environment’s protection and conservation and that people’s lifestyle influences the environment negatively 26.\r\n Bibliography\r\nShen, J. â€Å"China’s Future world and Development Challenges”.
