Ateneo de Madrid highlights 'Europe's Night against Light Pollution', emphasizing the significance of night-time biodiversity preservation
The issue of light pollution has gained significant attention as it poses harmful effects on a wide range of living species, inducing unwanted behavioral and physiological changes. According to Jaime Zamorano, a professor at the Universidad Complutense de Madrid, this issue is not given the recognition it deserves.
Currently, 23% of the Earth's surface between 75°N and 60°S is already contaminated by artificial light. This number is alarming, especially considering that 80% of the world's population lives under skies polluted by light. The problem is not so much the increase in electricity consumption but the type of lamps we are using, which are very bright and very unsustainable.
In an effort to raise awareness about this issue and advocate for the protection of dark skies, the European Light Pollution Awareness Network (ELAN) and the Asociación para la Defensa de la Calidad del Cielo (ADAC) are organising 'The Night of Europe' against light pollution. This event will be presented at the Ateneo de Madrid on a specific date, with the participation of scientists, communicators, politicians, and citizens.
The main victims of light pollution are rural areas and natural spaces, as stated by Jaime Zamorano. Light pollution disrupts the natural day and night cycle, blurring the boundaries between day and night. This disruption affects not only wildlife but also human health. Electric light generates sleep disorders, glare on the road, and has somewhat worrying correlations with diseases such as obesity, diabetes, and some types of cancer.
The night in natural conditions of darkness is essential for human biological regeneration and the balance of ecosystems. Astrophysicist Alejandro Sánchez de Miguel, a participant in the event, notes that most biodiversity is nocturnal. Light pollution can affect pollinating insects and migratory birds, potentially disrupting entire ecosystems.
Moreover, the loss of dark skies compromises astronomical research that allows us to protect ourselves from asteroids that could impact the Earth or discover how the laws of nature work. In France, around 12,000 municipalities turn off their public lighting totally or partially during the night, setting an example for other countries to follow.
Despite the existence of national legislation on light pollution in Spain since 2007, it is too vague and not effectively applied. It is crucial to adopt more responsible lighting practices to mitigate the harmful effects of light pollution. The Night of Europe aims to claim protection against light pollution and the value of dark skies, and the right to the firmament.
In conclusion, the Night of Europe against light pollution is a significant step towards raising awareness about this often overlooked issue. By uniting scientists, communicators, politicians, and citizens, the event hopes to encourage more responsible lighting practices and protect our planet's dark skies.
