Effects of Overpopulation in China Essay

This literature review discusses the impacts of over population on the environment in China through quatern main studies. Each hold clubhouse its question on one consequence the pissing issue and the aquatic ecosystem, the overexploitation of lay and resources as well as the extinction of super acid body politic, climate change, GHG emission and desertification of land1. Several methods and sources were used such as compelStateResponse (PSR), urban-rural population personate or other research papers written previously2. The results of these studies brightenly show that the overpopulation has multiple negative impacts on the Chinese environment and that strategies and policies regarding these issues should be open up.The population of China is growing exponentially and it is a serious issue because of its impact on the environment. The water insufficiency is growing and as it is presented, the expectations of the Chinese people exceed the capacity of the land3. Since the population of China is change magnitude fast, the urbanization of land and the rude emergence adjoin at the same rhythm4.As it is presented, human activity and human absorption are the main explanation for climate change5. concord to Shijie Wangs study, the southwestern United States of China is experiencing a desertification, in other words the land becomes manage a desert left with no resources6. Each article presents a different way of conducting its research to prove its point. In Qian Hong et al. research, the methods used to fall out the study are PressureStateResponse (PSR), the landscape environmental science method and Remote Sensing Global Positioning System (RS-GPS) 7. According to the authors, there are three types of indicators Pressure indicators, State indicators and Response indicators7.The indicators all presented a high up or a low number. If the number is high, it nub that the character suffered from important water degradation if the number is low , it means the opposite7. The outline of the research is made through a process called Analytical hierarchy process (AHP) that has four specific indicators7. Jianfa Shens study uses urban-rural population model to do predictions about the density of the population and is also represented as spatial demographic-economic model 8, whereas Shijie Wang conducted its research by investigating the studied part and by using indicators such as aerial photos and satellite images. He then compares and analyses the results with previous images and researches from the land9. The only piece of work that did not use any kind of Research method was written by Hung Ming-Te et al. who preferred to write the paper in type to researches and studies made and scientific predictions 10. One of the most important consequences of overpopulation is the expanding deficiency in water resources. Investigators urbane in six districts of China which are part of one constituent (Jinan) that was recognized f or its important source of water, aquatic ecosystem and surface. Due to industrial phylogeny and human actions the water checker became polluted and rarer11. Researchers found that water deficiency and erosion, rainy climate, miserable land vegetation, climate change, loss and decrease of agricultural performance, 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 direct subjoind rapidly and the national security is at risk. GHG growing yield would also make the lack of water and glow pollution worse than it actually is also they stated that climate change, in addition to organism caused by overpopulation, is influenced by poor sustainable development, poor resources management and over-use of energy.This study shows that such changes have 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 exceeding use of natural resources is a threat for the environments protection and conservation 14. Hong et al. are from the same opinion when they wrote that water condition is getting worse and it affects Chinas populations life-style as well as the aquatic ecosystem 15.10 Hung Ming-Te et al., 363-36611 Qian Hong et al., 32112 Shijie Wang et al., 127-12913 Hung Ming-Te et al., 363-36414 Jianfa Shen, 3915 Qian Hong et al., 319In the field of environment, every single factor is closely related to another one. Each of the four studies shows how the desertification of land, the migration, the exceeding use of resources and the poverty 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 survive and feed their families, have to increase the production of grains. T he overexploitation of the land then leads the land to become rocky 16. According to Shens study, market-gardening is over-used and China has to import grains to meet the populations needs17. The declension of the environment and the issue 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 trying 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 people there is, the more resources needed 20. The biggest riddle China is facin g is the lack of policing and measures adopted regarding the protection of the environment. According to Ming-Te et al.,16 Shijie Wang et al., 13117 Jianfa Shen, 3618 Shijie Wang et al., 12419 Shijie Wang et al., 124-131 Jianfa Shen, 36-39 Hung Ming-Te et al., 363-364 20 Jianfa Shen, 35-36 Chinas way 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. specified that the conservation and the protection of water 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 preserve the environment.Studies 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 t he 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 tender instability make the process happen faster. The consequence of overpopulations production of sulfur dioxide in the atmosphere exceeds the national average for smelting sulfur by over 13.8 times in some regions such as Bijie and Zunyi which causes air pollution and desertification of land 23.The results of the study conducted in the region of Jinan by Qian Hong et al. distinctly showed that this region has the best 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 relative frequency and strength of natural weather disasters 25. Jianfa S hen suggested that the exceeding use of natural resources repayable to the increasing density of population is a threat for the environments protection and conservation and that peoples lifestyle influences the environment negatively 26.BibliographyShen, J.
