The Last Bastion of Darkness: The Effects of Light Pollution

This article sheds new light on the problem of night sky pollution, defining darkness as a fundamental environmental ontology and a necessary selection regime for the biosphere. The author argues that artificial lighting has ceased to be a mere aesthetic issue and has become an aggressive ecological actor, disrupting circadian rhythms and creating traps for migratory species. The text analyzes the loss of night in economic terms as a negative externality and degradation of natural capital. It points to the need to recognize darkness as a common good, protected by law, in order to preserve the biological integrity of the planet and our cognitive relationship with the cosmos, symbolized by the figure of the astronomer fleeing the glare of civilization.
