Main Cause Of Environmental Issues In China Environmental Sciences Essay

Main Cause Of environmental Issues In china environmental Sciences EssayPopulation line of works argon one of the worlds most grave social problems, and they be the cores of numerous contemporary social problems. Also, population problems are closely connected to surroundal issues, and the earth is threatened by them. there are different kinds of population problems which main trim down china is facing now, and the problems of Sole youngster policy expect begun to show First, the overpopulation problem second, the population aging problem third, the decline of population quality problem. The statistics show that chinaware has the biggest population in the world, and there are probably 1.3 billion flock in mainland China. In addition, the speed of population appendage is amazing that the average annual branch rate is up to 0.57%. Large population and weak droping capacity are the basic guinea pig conditions of China at this stage, and it is difficult to change in a sho rt time. The population problem is a long-term problem in the primary stage of socialism in China, and it may calculate to limited preferences, less sustainability of the earth, and the poorer population quality. These results are all main causes of environmental issues in China, and the Chinese regimen has paid attention on these problems.why China has too much population?The inaugural power is that China has low cost of having children. The lower cost of having children in the place, there ordain be the higher(prenominal) density of population. The geographical feature in China is that the western part is high, and the eastern part is low. The highest Tibetan Plateau in the western region has average 4,000 meters of altitude above sea level, and to the eastern coastal areas, it is less than a few hundred meters. This ter rainwater condition is affect by Pacisic monsoon, which makes the rains concentrate on May to December. Also, the growth of crops needs moisture and temp erature, and May to December in China has both heat and rain in the same period, these make China suitable for food planting, in particular for the cultivation of high-yielding rice. In such areas suitable for the cultivation of rice, there leave be more(prenominal) grain output in the same proportion. using food as a unit of account to calculate, China has a lower cost of dependents. Therefore, a larger number of dependent provide make the population density be larger.The secondly reason john be that China has different cultures and different religions. Ancient Chinese apprehension that no offspring was a big problem, and in order to carry on the family line, they needed early marriage and childbearing traditions. Also, they were desired for sons, and they would not stop having babies until a son was born because they thought sons could support the parents when they got old. In addition, there can be another religious factor such as the East Asian religions re inexorable a bortion. These directly cause that all(prenominal) family has many children, which is a basis of overpopulation in China today.The third reason of why there are many people in China is that after the liberation, medical conditions greatly improved, and the survival rate of babies was highly improved. Also, president Mao in that period suggested that more people would have more power because of the use up of labor for the technology backward and lack of troops power that time.In brief, these three reasons show that China has a immense population base, and with the growth of the population e precise year, it leads to overpopulation in China, which results in a series of environmental issues now.Why overpopulation in China causes environmental issues?With the growth of population and the improvement of product tools, the depth and breadth of the usage of the spirit are perpetually expanded, and humans interference on ecological environment is bigger and bigger. When peoples busin ess activities reverse natural original balance and coordination, and the character cannot make up itself for the damage by human activities, there volition be a series of ecological environmental issues. It can be reflected through many aspects such as limited resources, serious contaminant, and travel by in biodiversity.Because the population is becoming bigger, the demand of in dissipatery for resources and economy in China is becoming bigger. However, the industry is like a double-edged sword, and at the same time it brings prosperity and civilization, it also brings negative set up. Due to mingled reasons, Chinas not very large industry destroys natural ecosystems, and increases environmental pollution. From a domestic perspective, as city as a center, the range of environmental degradation is still expanding soil wearing away and desertification degree aggravated resource destruction and waste is widespread, and some important resources gap gradually widened. Environment al pollution and degradation become one of the main factors restricting the sustainable development of Chinas economy and threatening the health of people.In 2002, the worlds forest coverage rate is 31.3%, scarce China is only 14%. Due to the stupid use of pasture, the grasscommonwealth shows degradation, desertification, and salinization trends, and the average grass yield decreased by 30%-50%. In the arid and semi-arid areas, precipitation is far below evaporation, and vegetation is fragile and the ecology is fragile. The mild human activity is likely to lead to land degradation and desertification. China is one of the worlds most serious soil erosion countries, and serious soil erosion and desperate short of water resources eventually led to the devastating floods and Southwest drought in 2010. In northern China, the desert, Gobi, and desertified lands have griped 1.54 million square kilometers, accounting for 16% of the total land areas.Also, the biodiversity is continuou sly decreased. According to Stancheva, she said that All of the previously described effects of overpopulation on the environment lead to the destruction of the natural habitat of many uncivilizedlife species (Stancheva). Chinas biodiversity is very rich, and higher plants and biological species account for 10% of the world. However, biodiversity is under a double threat from population growth and environmental degradation. Nearly half a century, China has more than 1,000 kinds of species extinction, which include about 200 species of higher plants. 15%-20% of plants and animal species are endangered, including about 4,600 species of higher plants and 400 kinds of wild animals.In addition, because of overpopulation, the industry activities become more important, which brings population. The air pollution is very serious, and the quality of atmospheric environmental in more than 500 cities cannot reach international standards. The pollution comes mainly from coal-fired release of c arbon dioxide, sulfur dioxide, smoke, dust pollution, and automobile exhaust pollution. In addition, the quality of water environment is deteriorating repayable to industrial wastewater discharge. The levels of pollutants in the water environment is far more than national quality standards, even infiltrating contaminated groundwater, which leads to the situation that local residents have no water to drink. Also, the emissions of solid waste are increasing, but the interposition rate and comprehensive utilization rate is not high. Finally, the noise pollution in the city becomes a major hazard. National regional environmental noise pollution rate is among the highest in the world.In general, higher demand for industry activities causes a series of environmental problems such as the muddled of forest, the soil erosion, the decrease in biodiversity and pollution. Also, higher demand for industry activities is a result of overpopulation. Therefore, overpopulation is an indirect facto r of environmental problems.The resolving powers for environmental problems caused by overpopulationThe first solution is that accelerate the progress of science and technology to improve the sustainability. The administration must enhance Chinas resources alternative capacity and ability to regenerate the government also needs to enhance the assimilative capacity of the environment to visit waste emissions. The second solution is improving education and health situation, and enhancing peoples quality. Environmental issues are very close to peoples quality problems, and sustainable development requires ever-changing the traditional values of the environment to make everyone shoulder the responsibility to get on human harmony with the environment. The third solution is insisting on the national policy of family planning to reduce the burden on the environment. It is necessary to strict control of population growth, and to make the population growth rate in the level of which econ omic power and the supply of resources can withstand. The final solution can be improving resource utilization and reducing resources wasted. To asseverate resources not only needs to reduce waste of resource consumption, but also must reduce the waste of resource development. At present, China has a serious waste in resource development. Also, strengthening the solicitude of resources and improving resource utilization are an important part of the coordination of relations between people and lands.In conclusion, overpopulation is one of Chinas population problems, and if the government and people do not pay attention on it and do not have some solutions for it, there will be a enormous damage to the environment.
