Emozionanti, tradizionali ma anche estremamente inquinanti. I fuochi d’artificio sono un appuntamento immancabile la notte del 1. agosto, ma in tempi di accresciuta sensibilità ambientale in molti si interrogano sull’opportunità di festeggiare ancora con spettacoli pirotecnici.
La combustione dei fuochi d’artificio può aumentare in misura notevole, almeno per breve tempo e a livello locale, la concentrazione di polveri fini.
Anche l’Ufficio federale dell’ambiente ha analizzato in uno studio gli effetti dei fuochi d’artificio sull’ambiente e ne raccomanda un uso prudente.
Delle alternative iniziano a prendere piede, come lo show di laser andato in scena nella località di Bremgarten (AG) nel 2018 o più recentemente allo Züri Fäscht 2019 dove ad illuminare il cielo sono state decine di droni.
