You've a short memory and you're losing your sense of proportion - https://en.wikipedia.org/wiki/2010_eruptions_of_Eyjafjallaj%C3%B6kull; Etna, Stromboli and several other volcanoes are banging away all the time and have been banging away continuously for centuries, producing fa-aa-ar-and-away more atmospheric pollution than a bunch of fireworks. Or a bunch of old motorcycles being ridden every day.
Last night, I didn't want to stand in the pissing rain watching fireworks. So I didn't. If other people wanted to, good luck to 'em. Live and let live.
