Loss of biodiversity due to climate change
According to a research paper published in the journal Biological Conservation, there is a rapid decline in the number of insects around the world. Reasons like reduction in their habitats, invasion of harmful insects,
and climate change may be responsible for this, which has been ignored. In the presence of intense artificial light at night, where activities like development, reproduction, and mobility of insects are adversely affected,
the insects that destroy them get a favorable environment. However, lighting facilities called arc lamps were introduced as early as the year 1800 to destroy and control harmful flies and mosquitoes.
Insect conservators believe that many species of beneficial insects are being destroyed or their numbers are declining wildly from the point of view of agriculture in the bright light overnight.
In some studies, due to this, the number of insects that are active during the day has also been estimated to decline. Insects move from one place to another on a large scale during the breeding season and on a smaller scale for food and habitat needs.
But artificial light affects the movement of a large number of insects. Insect experts believe that the reproductive processes of insects are delayed in the presence of artificial light. Lizards, frogs, and many other animals feed on millions of insects during the whole night under bright lights.
This process continues unabated in areas of artificial light. However, the effects of the presence and intensity of artificial light on insect diversity are not fully understood, requiring extensive research.
Large electric bulbs used in the olden days emit strong heat, while the ultrasonic heat emission of modern LED bulbs may have many harmful effects on the life and health of insects that need to be known.
Light pollution can pose a serious threat to many aspects of life on Earth. Studies have shown that light pollution seriously affects the natural aspects of our planet such as habitat, diet, and reproduction of birds, bats, and insects.
Migratory birds are guided by naturally available light to fly very long distances, sometimes thousands of kilometers, to search for new habitats when conditions are unfavorable and return to their permanent habitats when conditions are favorable.
Obstruction of the natural light and loss of life due to collision with road obstacles especially tall trees and high-rise buildings increases in artificial light
According to another study, due to artificial light, the number of nocturnal insects and caterpillars decreases by almost half. This affects the animals that use them as food.
Artificial lighting also severely affects the breeding cycle of bats and their habitat. Apart from these, artificial light seriously affects the natural activities and habitats of many creatures such as birds and animals that are active at night, such as owls, mice, and frogs.
