代写essay：如何治理空气污染
空气污染已成为生活在北京的人们关注的一个主要原因。空气中的主要污染物是颗粒物，包括一氧化碳、氮氧化物和二氧化硫。北京拥有中国1900多万人口，自过去三十年来经历了重大的发展(Schipani, 79)。在此期间，整个首都的污染源都在增加。自3月份以来，首都北京已经推出了新的空气质量下滑尺度;2015年，北京市首次发布红色预警。煤炭是北京空气污染加剧的主要来源之一，因为中国本身就是煤炭的第一大消费国。污染源的急剧增加、工业化程度的提高和化石燃料使用的增加，都使得北京的空气在几个地区几乎无法呼吸。红色预警系统作为一种减少污染和保护健康的方法被引入，当污染水平在一个月的特定时间是非常严重的。

众所周知，北京的二氧化硫通量可以忽略不计，而氮氧化物的信号却很小，这可能是由于北京附近限制建设煤炭的政策所致，而且在更广泛的范围内一直在应用缓解污染的技术。自2006年以来，中国一直是世界上最大的温室气体排放国(Wang and Jiming, 5)，根据2009年的哥本哈根协议，中国考虑到2020年将其排放量在2005年的基础上减少40% – 45%。中国科学家警告称，中国有毒的空气污染已经加剧，这带来了一个核冬天，因为它减缓了植物的光合作用过程，在未来，可能会对中国的食品供应造成严重破坏。这个国家的一大片农田受到严重污染，因为这些地区的工业已经被禁止种植粮食作物。此外，中国三分之二的地下水不适宜人类饮用和接触(Schipani, 77)。

Air pollution has turned out to be a major cause of concern for the ones living in Beijing. Out of the major pollutants of air are particulate matters (PM) that include carbon monoxide, nitrogen oxides and Sulphur dioxide. Beijing resides more than 19 million of the population of China, and has been experiencing major development since the last three decades (Schipani, 79). In this period, there has been an increase in the sources of pollutants across the capital city. Since March, the capital of China has introduced new scale of sliding for the quality of air; after the city was issue its first red alert in the year 2015. Coal is among the main sources increasing the level of air pollution across Beijing as China itself is the first biggest user of coal. Dramatic rise in sources of pollution, enhanced industrialization and increased use of fossil fuels have all left the air of Beijing almost impossible to breath in several areas. The system of red alert has been introduced as a way of reducing pollution and protecting health, when the level of pollution is extremely during specific times of the month.

Beijing is known for having negligible flux of Sulphur oxide, irrespective of a large signal of nitrogen oxide, possibly due to policies for limiting the building coal within the vicinity of Beijing, and in a more extensive way has been applying the technologies of mitigation. China has been the biggest emitter of greenhouse gas of the world since the year 2006 (Wang and Jiming, 5). Under the Copenhagen Accord of the year 2009, China considered reducing its intensity of emissions by 40 to 45 percent from the levels of 2005 by the year 2020. It has been warned by the scientists of China that the toxic air pollution of the country has enhanced, which brings in a nuclear winter, as it slows down the process of photosynthesis in plants and further ahead, potentially wreaks havoc across the food supply of the country. A large area of the farmland of country is highly contaminated from the run- off of industries that the areas have been banned from the growth of food crops. Also two- thirds of the underground water of China is inappropriate for human consumption and contact (Schipani, 77).
