Fireworks spraying plastic all over the suburbs

As far as I have observed, in many countries there’s a restricted period each year that fireworks are allowed or can be sold. In New Zealand it’s in November which has recently passed. After “fireworks night” I’ve observed pieces of plastic all over the ground and as it gets washed over the roofs and, down the drains, many pieces of plastic have ended up in drain filters.

This pollution is a pretty big encumbrance on the environment and home-owners!
