Light Pollution in Hong Kong: An Environmental Nuisance

Have you seen Starry Night in Hong Kong? According to the Hong Kong University Faculty Survey, Hong Kong is the most polluted city in the world, the night sky of the local city is 1000 times brighter than the international dark sky standard. Hong Kong's light damage not only affects the visibility of stars but also leads to waste of energy and adversely affects ecosystems and living standards, but technical control measures, education, and laws are fundamentally There is a possibility of solving the problem.

However, the most contaminated places in the world are Hong Kong and China. In March 2013, the University of Hong Kong ranked this city as the most contaminated city in the world. According to the survey of the university, the night sky of the Tsim Sha Tsui block in southern Kowloon is 1,200 times the brightness of the average city sky. This level of light pollution is increasing worldwide. In the 2010 Ecology and Society Journal article, Hellerkers point out that the use of artificial lighting increases by 20% each year in some areas, and the urgent need for pollution policies beyond human, animal, and energy efficiency Pointed out. environment

This process uses little fuel and uses only ambient air. Like today's space shuttle, the use of such aircraft is infinite, and small satellites will be launched on orbit and future launch vessels. This idea is no longer a product of SF but a reality. All of these can be achieved by controlling the physics of everything in our daily lives.

Over the last decade, light damage has been widely discussed in Hong Kong. Some people demand the government to do their utmost to develop a strategy to effectively solve this environmental problem. It is necessary to implement various short-term and long-term measures such as education, advocacy, law enforcement. Apart from the government, all industries - families, communities, public sectors and the private sector at every level - must also recognize their role in mitigating Hong Kong light pollution problems. In fact, the environment is a public resource that requires a community-wide joint effort to protect. Good news is that everyone is keen to solve this problem and in the near future we will create a better, lighter, polluted city for ourselves and our next generation, here Living in Japan, working and working.
