Gli effetti nocivi dell'inquinamento luminoso, percepiti da insetti e animali, si ripercuotono anche sulla salute umana. Per sensibilizzare l'opinione pubblica, martedì scorso è stata lanciata una petizione a livello federale, mentre a Ginevra è stata adottata all'unanimità dal Gran Consiglio una mozione sulla creazione di zone buie durante la notte.
L'obiettivo non è la soppressione dell'illuminazione in città, bensì la riflessione sull'uso della luce artificiale nelle varie aree a seconda dei diversi momenti della notte, ha precisato Christina Meissner (PPD), che ha firmato il testo. In particolare, è prevista la realizzazione di una mappa con l'indicazione di corridoi completamente bui.
L'inquinamento luminoso ha degli effetti nocivi sull'uomo, dal momento che altera il bioritmo. Anche la flora e la fauna ne subiscono le conseguenze, hanno rilevato alcuni studi.
