Photos: Light shows, drones could replace traditional fireworks for greener future

The article discusses the environmental and health concerns associated with traditional fireworks, which rely on metal salts like strontium, barium, and copper to produce colors but release harmful fine particles and plastic debris into the air, soil, and waterways. These particles pose respiratory risks and contribute to pollution, while the loud noise—often exceeding 120 decibels—disturbs wildlife and pets. To mitigate these issues, manufacturers are developing biodegradable fireworks made from paper, cardboard, and starch-based materials that break down more quickly, alongside cleaner chemical compositions that reduce toxic fallout and noise levels. However, these greener alternatives remain more costly and are not yet produced at large scale, limiting their widespread adoption. As an alternative to traditional pyrotechnics, drone light shows have gained popularity, using coordinated LED-equipped drones to create intricate aerial displays without smoke, debris, or loud explosions. These drones are reusable, reducing waste, though their lithium batteries have environmental impacts related to mining. Artists and companies worldwide are pushing the boundaries of
