Lose instinct because of excess light

Light pollution, a problem that occurs in most cities in the world, but has received little attention.

Common problems

Light pollution refers to inefficient use of artificial light, causing adverse impacts on the economy, environment and health. Many people think that light pollution is a problem only in big cities, where street lighting and advertising lighting systems are overused.

The reality is not so. A family on the outskirts of the city, every night, gets into the windows of a neighbor's house, which makes sleeplessness a victim of light pollution.

The bright streets connected with the dark alleyways made the people on the road dazzled, unable to adjust the steering wheel in time; The night sky was so stained by artificial light that it was impossible to see the moon clearly. These are all signs of light pollution.

Light pollution is increasingly popular

The price of civilization

Another consequence of light pollution is disrupting ecosystems. Non-scientific artificial lighting makes animals lose much of their natural instincts that are maintained based on day and night differences.

Lighting of street lights or decorative lights in buildings makes the birds migrate mistakenly as stars. They will be disoriented, fly indefinitely until exhausted or rush into buildings. Statistics from the US Fish and Wildlife Service show that between 4 and 5 million birds die each year from hitting buildings after being lost by advertising lights.

Many amphibians and amphibians are also affected by light pollution. Usually, at night, they wake up to find partners to mate. But the excessive illumination environment causes this activity to decline, leading to a marked reduction in the number of individuals of many frogs living around cities.

For human health, light pollution is also a serious threat. Many studies show that excessive lighting, inappropriate light colors cause sleep disturbances, headaches, fatigue, nervous stress, impaired sexual ability.

Many reputable medical organizations in the US and WHO also warned about the risk of abusing light at night to increase the risk of breast cancer. Glare (the contrast between the bright and dark areas in sight), one of the manifestations of light pollution is an important cause of traffic accidents.
