Wildlife in general
There are statistics showing that many animals are displaced due to fireworks each year, that birds actually drop dead and fall to the ground, and that rate of injury and accidents goes way up for large animals.
If that isn't enough on its own to convince you to put the fireworks away, consider the risk of injury to yourself, your friends and family, and the risk of fire that could damage your own property as well as that of others if it spreads. When you light the fuse of anything that goes up in the air you basically have no control over where it comes down. I have had still burning fireworks land in my back field before from neighbors four farms away.
And if that isn't enough, consider the likelihood that somewhere nearby lives a combat veteran with trauma and that the sound of fireworks is very similar to live fire.
I'll add in that not everyone wants to hear the noise of fireworks and when you set them off you basically ruin the holiday for all of us who prefer a quieter celebration.
When you set off fireworks to celebrate independence you basically trample all over the rights of others.
Why not go watch the fireworks set off by cities and towns? I'm not fond of those either, but at least they're controlled and they have emergency teams nearby in case they're needed.
Or you can spend your 4th of July the way I do - with cats and dogs sequestered safely inside, horses and donkeys contained in small paddocks near the barn, and a bottle of Rescue Remedy in hand to help all get through the evening.
