Fire works harm so many animals due to the noise they produce! Animals get scared and disoriented, run away and get lost. 
birds have panic attacks at night and cause mass flight and death. 
wild animals raising  babies are scared into leaving the nest and getting lost and disoriented and it ends in orphaned babies.  
Bees become disoriented and can’t find their way back to the hive. 
And let’s not forget that small children are very scared by the loud noises, as well as children and adults on the autism spectrum as well as other disorders. 
Many many veterans have PTSD and the noise is very upsetting, they can cause severe panic attacks, flash backs, self harm or cause them to inflict harm on other due to flash backs. 
I love our nation and I love Independence Day, I love New Years etc.. but there truly is no reason we can’t enjoy the fire works without the noise! Fire crackers and other noise only ones should be banned!  If we can get the law passed for only silent fireworks our society as a whole will be better off and our wildlife and pets will be much better off!
