What does light pollution do?

The consequences of light pollution are manifold, and the following is a detailed analysis and summary of these consequences:

Effects on human health:
Eye damage: Exposure to light pollution for a long time may cause eye fatigue, vision loss and other problems. Such as the reflected light of the glass curtain wall of the building, may cause pedestrians and drivers to feel dizzy, and even cause traffic accidents. According to experts, the dry light pollution in the visual environment can be roughly divided into outdoor, indoor and local visual environmental pollution, which may cause different degrees of injury to the eyes

Affect sleep: Excessive light at night can disrupt the human circadian rhythm, resulting in sleep disorders, increase mood disorders and other problems.
Increased disease risk: Light pollution may lead to decreased immunity and an increased risk of diseases such as cancer. People who are exposed to light pollution for a long time may have an increased risk of breast cancer, prostate cancer and other diseases.

Impact on biological environment:
Disrupts circadian rhythms: Light pollution disrupts the biological clocks of animals and plants, affecting their growth, reproduction, and migration. For example, lighting disturbances can cause birds to become disoriented, affect insect reproduction, and so on.
Disruption of ecological balance: Light pollution may also affect the balance of the entire ecosystem through the food chain and ecological networks. For example, urban light pollution attracts large numbers of insects, potentially depriving birds of a food source and disrupting the natural food chain.

Effects on astronomical observations:
Obstructing deep space observations: Light pollution in cities makes the stars blurred, making it difficult for astronomers to conduct deep space observations. This not only affected the development of astronomy, but also reduced public interest in astronomical science.

Energy consumption:
Excessive night lighting needs to consume more power resources, increasing energy consumption and electricity bills.
At the same time, it also increases greenhouse gas emissions and exacerbates the problem of global climate change.

Economic impact:
Human health problems and social problems caused by light pollution may increase healthcare expenditures and social costs.
The destruction of ecological balance may also affect the development of agriculture, fishing and other industries.
In summary, light pollution has a serious impact on human health, biological environment, astronomical observation, energy consumption and economy. Therefore, we need to take active and effective measures to reduce the impact of light pollution and protect our environment and quality of life.
