Fireworks displays create surges of pollutant ozone in lower levels of the atmosphere, where it is a respiratory irritant, greenhouse gas, and plant toxin. Some scientists believe fireworks are an “insignificant source of pollution”, because they occur infrequently; however, no source of greenhouse gases is insignificant considering our current climate crisis, not to mention the heavy metals and potassium perchlorate in these grand patriotic displays.
