Sign here to abolish celebratory fireworks.
Fireworks were developed for festivities in China during the Tang dynasty
as a means of expelling evil spirits.
They produced more frightening lights and noises than banging pots and costumes with mirrors.
Tell me, please. They frighten our pets,
but do they expel evil spirits?
Start here and maybe later we can abolish war.
