fireworks celebrations of light

i confess i avoid the fireworks celebrations of light. the faithful mobs of people gathering 4X a year around english bay and various parts of the world. do you know or even care that your free light show is pure toxic pollution? fireworks displays are basically propelled by the ignition of gunpowder a technological innovation originating mid 19th century. every person there watching is part of the problem because your presence is condoning the use of toxic pollution of our environment primarily air and water. do you enjoy acid rain? do you wonder why you get sick? depending on the effect sought, fireworks produce smoke and dust that contain various heavy metals, sulfur-coal compounds and other noxious chemicals. barium, for instance, is used to produce brilliant green colors in fireworks displays, despite being poisonous and radioactive. copper compounds are used to produce blue colors, even though they contain dioxin, which has been linked to cancer. cadmium, lithium, antimony, rubidium, strontium, lead and potassium nitrate are also commonly used to produce different effects, even though they can cause a host of respiratory and other health problems. is it really worth it? do we really need fireworks? what about all the litter and garbage and crime in the surrounding areas where these events are held? and the commuting and parking nightmare? how will you give back to the environment? what price are you willing to pay for your free 25 minutes of man made fabricated toxic lights shooting into the sky at night? no thanks. i like clean air and water.
