"US Cities Swap Fireworks for Eco-Friendly Drone Displays on 4th of July"

Some US cities, including Salt Lake City, Boulder, and various communities in California, are replacing traditional Fourth of July fireworks with drone light shows to address fire threats and environmental concerns. The shift is aimed at minimizing high fire danger and reducing air pollution caused by pyrotechnics. Factors such as increased fire danger due to climate change and difficulties in sourcing fireworks during the pandemic have influenced the decision. The drone shows offer a quieter, reusable, and more environmentally friendly alternative, eliminating issues such as smoke, debris, and noise pollution.
