I'd be for a national fireworks ban, personally, especially during the summer wildfire seasons.
But it wouldn't be fair to attribute the poor air quality today specifically to fireworks unless evidence links them.
The last 4th of July show I watched had designated people on the ground stamping out fires as they started. It seemed ridiculous to me for the city to still do them in such a dry area, but at least each little fire was put out within seconds. It was wild seeing the explosions happen, then tiny people running around and putting them out, occasionally with the help of a firetruck. In the end it worked out pretty well and none of the fires spread or lasted past the fireworks show. But still kinda unreal to witness...
