Stargazing experts said that Hong Kong is seriously polluted, and the accumulation of suspended particles in the sky affects the moon's color. Unless the air quality can be improved, the pure white moon is difficult to reproduce the public. Some environmental groups have encouraged the people of Hong Kong to turn off the lights in the Mid-Autumn Festival this year.
The study of the Hong Kong Astronomical Society has found that the sky in Hong Kong at night is 100 times lighter than that of foreign stars. When pollution is serious, it is 1000 times more than foreign light, which seriously affects the stars.
The environmental protection groups Tai Po Environmental Protection Association and Kadoorie Farm encourage citizens and commercial organizations to turn off unnecessary lighting equipment, such as façades on the Mid-Autumn Festival, in addition to reducing the use of electricity and reducing carbon dioxide in power plants. In addition to emissions, it can also reduce the light damage in Hong Kong, hoping to make the stars shine brighter in the past.
Mr. Qiu Rongguang, Chairman of the Tai Po Environmental Protection Association, said that more than 100 organizations and organizations have signed up for the event, including a computer store in Mong Kok. He expects participants to continue their energy-saving habits.
The group also arranged for the children to have their own moon cakes that I would like to enjoy the moonlighting stars every night, and gave them to the Director of Environmental Protection, Wang Qianyi. Wang Qianyi said that she strongly supported the event and believed that the public had a lot of space to reduce energy use in their daily lives. As for whether the SAR Government will participate in the operation, she said that if the operation permit is supported.
Star-watching expert Xu Litao said that Hong Kong's light pollution is serious. Energy consumption has caused power plants to continuously emit pollutants, air quality has deteriorated, and the moon has turned yellow. He pointed out that the lights in the nights of many buildings made the sky very bright. He estimated that the luminosity of the moon should be -10 stars under normal circumstances, but only in most of Hong Kong - The luminosity of 13 stars.
In addition, the Tai Po Environmental Protection Association and Kadoorie Farm jointly organized a series of energy-saving and carbon-reduction schemes a year ago. They loved the Earth. On the 17th, they were joined by eight non-SAR government groups to jointly reduce carbon dioxide emissions by 5,000 tons per year. Qiu Rongguang said that after the launch of the event for one year, 140,000 citizens have registered online to commit energy conservation and emission reduction, and the total reduction of carbon dioxide is 14,000 tons, equivalent to the volume of 80,000 double-decker buses.
