The effects brought on by polluting of the environment and the conversation on the suggested alternatives in conditions of ecological development
With the rapid development and urbanization in Hong Kong, the quality of air deteriorated scheduled to a great amount of air pollutants released into the atmosphere, and adding to the greenhouse impact as well as worsening global warming. This article is split into two parts, the first part is briefly talk about the unwanted effects brought on by serious air pollution in conditions of lasting development, and the next part is an in depth dialogue of the suggested alternatives.
The effects induced by air pollution can be talked about in conditions of lasting development with three aspects which are inter-related, inter-dependence and similarly healthy, and these aspects are environmental, cultural and economical aspects. In conditions of the environmental aspect, the worsening quality of air will fasten the greenhouse result with a rise in temps and adding to global warming.
In terms of the interpersonal aspect, "the earth Health Organization estimates that every year, 2. 4 million people expire from causes associated with air pollution" (Sierra-Vargas & Teran, 2012, p. 1031). It shows how air pollution causing health influences on people. The worsening quality of air increases the threat of having "respiratory diseases, cardiovascular diseases, or cancers" (Deguen et al. 2012), and matching to Sierra-Vargas and Teran (2012), people who are active outdoors, people with diseases and elderly are in higher health risk. These pollution-related ailments are affecting the grade of life because these health problems not only shortened the life span expectancy and induced the subconscious stress, but also increased the costs on healthcare. Therefore, serious air pollution causing pollution-related health influences in the cultural aspect and increasing the expenses on health care in the economic aspect.
Apart from the communal aspect, the poor air quality with low presence and high awareness of greenhouse gases in the atmosphere also produce negative effects in the economic aspect. Deteriorating quality of air affects local travel and leisure industry and the foreign investment. Corresponding to Laws and Cheung (2007), the tourism industry in Hong Kong has threatened by the deteriorating quality of air, regarding to the huge monetary contribution from the tourism industry, poor quality of air may decrease the willingness of travelers to travel in Hong Kong. Besides, some overseas opportunities are retreated plus some professionals won't work in Hong Kong due to poor working environment with worsening air quality. All these monetary impacts will weaken the competitiveness of Hong Kong and leading to unexpected economic deficits which in turns suffered by the complete society.
From the examples mentioned previously on the impacts in three specific categories, we can observe that air pollution brought on adverse impacts at both individual and sociable levels. Therefore, "[i]n order to safeguard the air quality from deteriorating further, more initiatives should be made by the federal government, as well as by population to make Hong Kong a clean and safe spot to travel also to live" (Law and Cheung, 2007, p. 398). Both HKSAR federal government and the public should be accountable for the improvement works on air pollution, such as a strong pertinence coverage together with energetic public involvement.
The most significant and effective long-term air improvement insurance policy should be the adoption of lasting development procedure with an equal balance between your environmental conservation and the monetary development. Hong Kong is a well-known financial-based metropolis round the world. Therefore, the federal government mainly puts emphasis on the monetary development, but neglected the importance of environmental conservation, in other words, the federal government weighted the financial development over environmentally friendly conservation, and therefore leading to environmental destructions through the process of economic development in Hong Kong.
However, it is hard to make equal balance between your financial development and the environmental conservation, and the co-existence of both aspects may be in a low probability, because taking care of must make scarification when the other one is out there. For instances, lands for economic development propose make a great amount of particles particulates during development and resulting in poor quality of air with low presence. Simultaneously, the quality of air improvement procedures for environmental conservation purpose spend plenty of government expenses. But, regarding to the serious problem of air pollution in Hong Kong and the related unique negative outcomes caused, environmental conservation should get the first goal and financial development should come the second.
The second possible solution is urban greening. Vegetation performs an important role in air purification because vegetation can absorb skin tightening and and release air through photosynthesis. In order to improve the air quality, the government should carry out metropolitan greening to improve the renewable areas through proper city planning in the cities, especially in the internal metropolitan areas and heavy traffic areas, such as MongKok, Wan chai, Causeway Bay and Tsim Sha Tsui. However, limited spaces with densely distributed design of skyscrapers in the cities create hurdles on metropolitan greening and the use of the valuable lands for growing vegetation in cities may result in voices of disapproval. But, there are two possible ways of metropolitan greening, the first solution, matching to Sierra-Vargas & Teran (2012), is making good use of rooftops for growing crops, the government will give economic incentives to the house owners for the encouragement of planting vegetation on rooftops. The second you are re-planning the prevailing parks with an enlarged percentage on the area of vegetation. Both of these solutions can make the best use of the available space resources that not require extra space on the ground floor.
Sources of pollutants in Hong Kong are mainly from power vegetation and vehicles, so strong pertinence plans on these two options are needed. The first solution, matching to Sierra-Vargas and Teran (2012), promoting the use of the landfill gases among the energy resources is a possible way to improve air quality with a land in the quantity of contaminants. Mexico is one of the successful places that converts "landfill gas into electricity and capabilities the light rail transit system and city neighborhood lighting at night" (Sierra-Vargas and Teran, 2012, p. 1036). The Hong Kong authorities should analyze from the instances of Mexico and perform a suitable plan based on the ideas seen. The alteration of landfill gases into useable energy can decrease the greenhouse gases being released into the air. Another solution is promoting the extensive use of alternative power instead of non-renewable power in order to change to a cleaner way for power generation, such solar powered energy and wind power. However, there are two troubles in using landfill gases and adoption of renewable electric power resources. The first hurdle is a great amount of authorities expenditure is necessary for the construction or installing the specific electricity plants, like the regular maintenance of the energy crops. Besides, the opposition from environmental coverage groups could also grow because this vitality generation method is not classified as renewable electric power. In the event the opposition raise, it is better to take the next solution rather than both solutions in order to avoid social conflicts based on the problem talked about.
In terms of the vehicles, the federal government should work together with two bus companies to handle the discussion about the growth of the service area and raise the service provided to the public. The HKSAR authorities can use monetary incentives or commit to increase the operating capital of two bus companies. With better bus services provided, the determination of people for taking public travelling to school or to work will be increased and so less energy is employed and less contaminants are emitted in to the atmosphere.
Apart from the plans mentioned above, the active public involvement on the reduced amount of air pollutants is very important and it should be made by every citizen, including the using of open public transportation instead of private autos and reduce the use of energy means less air pollutants are released by burning up non-renewable vitality resources, such as coal. Also, citizen should actively take part in the appointment of the government regulations launched for bettering the quality of air.
Air air pollution is a serious problem which created many negative effects, and a highly effective extensive solution with an extended period for in depth and careful planning is needed for improving quality of air. It really is beneficial when better quality of air can be found in Hong Kong. Although the problems of polluting of the environment cannot be totally eliminated, the more work we pay resulting in a higher chance for us to make changes and improve the quality of air.
