How to reduce the impact of light pollution on fireflies?
Light pollution is getting worse at night, The International Firefly Organization launched an initiative calling for minimizing the negative impact of ALAN on fireflies by reducing non-essential lights at night and modifying lighting equipment.
There are few fireflies in the city, and it stands to reason that it will not directly affect their population. But the various strong light sources in the city work together to create a pollution called sky glow (one of the ALAN types). The sky glow has a wide range of effects, even illuminating suburbs, which in turn affects fireflies in rural environments.
In fact, a simple modification of lighting facilities can reduce the impact of sky glow, for example, adding a cover to the omnidirectional light source or appropriately lowering the position of the light source can minimize the divergence of top light without affecting the lives of residents.
For people living in suburbs or villages, there may be an ecological environment suitable for fireflies to live around. At this time, the light source of daily life can be replaced with voice-activated lights or timed lights, which can significantly reduce the direct impact of light on fireflies. A more practical suggestion is to replace traditional light sources such as sodium and mercury lamps with LED new energy lamps, which are more energy efficient and durable.
In addition to the economical advantages of low energy consumption and long life, LED lamps also offer better ecological benefits--Because the wavelengths emitted by conventional sodium mercury lamps attract a large number of nocturnal insects, moths are a typical example. In contrast, LED lights had a smaller combined effect on nocturnal insects and attracted significantly fewer insects.
Humans are also victims of light pollution
The disturbance of light pollution to organisms is comprehensive and extensive. In addition to fireflies, other animals (such as moths, bats, birds and amphibians, etc.) and even plants are adversely affected by excessive nighttime light. Of course, humans are no exception. Long-term light pollution will cause harm to many physiological and psychological activities such as sleep, emotions, and endocrine.
Whether it is human beings or all kinds of animals and plants, we, as part of nature, are not fully adapted to this era of brilliant night sky. In today's increasingly advanced technology, how to make those animals and plants that have adapted to the dark life for millions of years can continue to live comfortably and comfortably, is one of the issues that we should also consider when coexisting with nature.
