How Does Light Pollution Effect on Wildlife?

Pollution is different, although we are all accustomed to lamenting the chemical pollution of the environment through the emission of plants, factories, motor vehicles, pesticides, and mineral fertilizers. However, there are also sound, electromagnetism and even light pollution. Excessive and incorrect use of light enhances light pollution. This kind of pollution is a side effect of industrial civilization and is most common in densely populated and highly industrialized regions. It has a bad effect on not only on people but also on animals (moray eel are also victims of noise pollution).

What Do The Effects Of Light Pollution On Wildlife?

Light pollution can destroy the ecosystem, especially the night wildlife. Excessive illumination can confuse migratory animals, change the relations of predator-victims or the competitive interaction between species and even cause physiological damage. Natural daily patterns of darkness and light dictate life in the wild, so their violation can affect the ecological dynamics.

Daily cycles – changing day and night, lunar cycles – changing the phases of the month, and the annual cycles – changing the seasons and the duration of the light day. This plays great importance in the physiology of animals. First of all, this is expressed in the hormonal balance: a longer light day or the onset of a certain phase of the place these are signals before reproduction. All these physiological processes are radically disturbed in animals because of light pollution. The brightly lit streets create an illusion of longer daylight and a full moon. Accordingly, animals react very ambiguously, often, showing behavioral reactions are not inherent for a particular season.

How Does It Effect On Insects?

Light pollution affects animals because they are mobile and respond immediately to the slightest changes. The effect of artificial lighting affects the behavior of animals, for example, many nocturnal insects are guided by the light of the stars and the moon, especially its phases, which are a signal to the beginning of reproduction, going to places of accumulation of their species, these insects find themselves sex partner.

In these behavioral reactions, artificial lighting has the greatest influence, breaking the natural course of a life of animals – the bright lights of large cities are perceived, for example, night butterflies, for the light of the moon in full. They fly to it, where, of course, they find themselves a couple, but there is a problem – after pairing the female is not where to lay eggs, because the absolute majority of forage plants in the cities does not grow, so the offspring are doomed to death before his birth.

But light pollution can have a negative impact not only on animals but also on people. Despite such radical changes in the lives and groups of animals, we cannot refuse street lighting in the cities, even if for security reasons. However, the output is – the introduction of lamps with a very limited spectrum of radiation that will not attract animals and will not change the organization of ecosystems, even in cities.
