Explosion of artificial lights harms nocturnal creatures and disturbs humanity

From a cultural perspective, we can be said to be the first generation to live the night as a continuation of the day.

A group of experts, journalists and activists called in an open letter to the newspaper “لوموند Le Monde, France, to reduce nighttime lighting in urban areas, and called on governments and international organizations to classify the starry sky as a World Heritage.

With more than 11 million public lighting points and 3.5 million advertising banners, the new ‘Age of Lights’ is close to putting out the rays of the night and its twinkling lights.

Explosion of artificial lights

The experts and activists who signed the letter believe that the “explosion of artificial lights” has grown by 84% over the past two decades in France, which has led to uncontrollable light pollution, and has had tangible negative effects on biodiversity, climate, public health and the shape of the sky when viewed with the eye. barebones. In addition to the destruction of the environment and the spread of pesticides, light pollution is a major factor in the disappearance of large numbers of insects and the disruption of biodiversity in general.

According to the activists, “we should not forget that 28% of vertebrates and 64% of invertebrates are considered fully or partially nocturnal creatures, and therefore are at risk of artificial lighting. Among the things that raise alarm bells, the disappearance of 38% of bats in France on over the past ten years.”

Another study showed that lawns exposed to light pollution recorded a 62% decrease in nocturnal pollinator visits compared to lawns that were not artificially lit.

The necessity of controlling the night lighting

The letter adds that “artificial light dramatically alters the biological cycles of organisms and the interaction and behavior of different species. These lights also threaten natural habitats at night, highlighting the need to create unlit areas for habitat conservation and restoration.”

Statistics show that the electricity needed for public lighting at night represents 41% of the total electricity consumption. A recent report from the French National Academy of Medicine proposes classifying exposure to night light as an endocrine disorder, given the health effects associated with exposure to artificial light.

Among the dangers of night light pollution, according to the message, is the effect on the shape of the sky, as less than 20 stars can be seen with the naked eye in cities compared to several thousand stars in night places devoid of artificial lights.

When the night is a continuation of the day

From a cultural perspective, it can be said – according to the activists – “We are the first generation to live at night as a continuation of the day, so we call for saving lighting and rationalizing its use to a minimum through strict measures.”

The International Union for Conservation of Nature held its annual conference in Marseille from 3 to 11 September last, during which a “Night Day” event was held to celebrate the beauty of the starry sky.

The signatories conclude their open letter by calling on “states, communities and international organizations to recognize the starry sky as a world heritage of mankind. We must all work to better take into account this common good and reduce the misuse of artificial light emitted by night lighting, whether public or private, including Including backlit advertising devices and bright satellite tower projects.”
