Reform spring wind blowing all over the land of God, the fire of reform and opening up burned all over the hometown, so that my hometown - Gaotang a new look, so that it becomes like a rich vitality of the maiden, Chu Chu moving people.

Listen to my father said, before, the hometown of a small cottage one by one, there is a two-story building on the good, the road is very narrow, only three or four bicycles side by side to go, a rain on the very muddy, as for the plaza ah, entertainment venues ah people are even not even heard of.

And now, high-rise buildings rise, towering over the clouds, one has a characteristic, one has a posture. Recreational venues are more up, not to mention, the light of the square there are several: Jincheng Square is a good place for people to play, especially in the summer evenings, the square south of the big screen in front of a lot of people watching TV, and teenagers in the music fountain next to the listener of beautiful and moving music, it is unforgettable.

Cultural Square has not yet been built, but very beautiful, at night, the colored lights to the square illuminated colorful, stroll among them, feel elegant to the extreme!

The biggest change in my hometown is the river, originally a stinky and piled up with garbage river, now turned into a beautiful and beautiful river, but the light pollution is following the exhaust gas, waste water, waste residue and noise and other pollution after a new source of environmental pollution, mainly including white light pollution, artificial daytime pollution and colored light pollution. Light pollution is threatening people's health.

White light pollution in the city's busy streets, many stores with large mirrors or aluminum alloy decorative facade, and some even from the roof to the ground floor of all the mirrors decorated, people are almost in a world of mirrors, and can not distinguish the direction. In the season of strong sunlight, the building's tempered glass, glazed brick walls, aluminum alloy plates, polished granite, marble and high-level paint and other decorative, bright, white, dazzling forced. It has been determined that the white stucco surface reflection coefficient of 69 ~ 80%, while the reflection coefficient of the mirror glass up to 82 ~ 90%, more than the green grass, forests, dark or hairy masonry decoration of the building reflection coefficient of about 10 times larger than the human body can withstand the range, thus becoming one of the new sources of pollution in modern cities. White bright pollution can harm the cornea and iris of people's eyes, causing vision loss and increasing the incidence of cataracts.

Artificial Daylight PollutionWhen night falls, big hotels, big shopping malls on the billboards, neon lights dazzle people, and some of the strong beams of light and even straight to the sky, so that the night is like daytime in general. Artificial daytime also has a negative impact on people's physical and mental health. Due to the reflection of the light, the neighborhood can be illuminated as daytime, making it difficult to sleep at night, disrupting the normal biological rhythms, leading to mental instability. According to a survey abroad, two-thirds of the people believe that artificial daylight affects health, 84% of people reflect the impact of night sleep. In order to avoid glare, people have to close their bedroom windows or install dark curtains. Artificial daylight can also harm insects and birds, as the bright light can disrupt the normal reproductive processes of nocturnal insects. At the same time, insects and birds can be burned to death by the heat surrounding the light.

Colored light pollution modern cabaret installed black lights, rotating lights, fluorescent lights and flashing colored light sources constitute colored light pollution, harmful to human health. It is determined that the black light can produce wavelengths of 250 to 320 nanometers of ultraviolet light, its intensity is much higher than the sun's ultraviolet light, the human body, such as long-term exposure to this black light irradiation, may be induced by nosebleeds, loss of teeth, cataracts, and even lead to leukemia and cancer. The harmful effects of this ultraviolet light on the human body can last 15 to 25 years. Rotating moving lights and colored light sources, dazzling, not only for the eyes, but also can interfere with the central nervous system of the brain, making people feel dizzy, unsteady on their feet, headaches, insomnia, lack of concentration, loss of appetite and other symptoms. Cabaret neon flashing lights in addition to damage the human visual function, but also can disturb the internal balance of the human body, so that the body temperature, heartbeat, pulse, blood pressure, etc. become uncoordinated, causing dizziness, irritability, loss of appetite and fatigue and insomnia and other light damage syndrome. Fluorescent lamps irradiation time is too long will reduce the body's ability to absorb calcium, resulting in the body calcium deficiency.

Now some of the luxury cabaret equipped with laser devices. According to the relevant health departments of dozens of cabaret laser equipment to do the investigation and determination shows that the vast majority of cabaret laser radiation pressure has exceeded the limit value. This high density of thermal light beam through the lens of the eye and then concentrated in the retina, the spot temperature can reach 70 degrees Celsius, which is very harmful to the eyes and brain nerves. It can not only lead to visual impairment, but also cause headaches and dizziness, cold sweats, neurasthenia, insomnia and other diseases of the central nervous system of the brain.

The latest research by scientists shows that colored light pollution is not only detrimental to human physiological functions, but also has an impact on human psychology. The color light lamps are not only a good choice for the people, but also for the people who want to have a good time.

At present, light pollution is not yet included in the environmental pollution prevention and control category, but its harm is obvious, and in the aggravation and spread. Light pollution has increasingly attracted the attention of scientists, they are trying to study the methods of prevention. People in life should also pay attention to prevent all kinds of light pollution on the health hazards, avoid too much exposure to light pollution for too long. We should actively create a beautiful and comfortable environment to minimize the threat of light pollution.
