One use that goes unnoticed is synthetic fabrics. Your polyesters, nylons, rayons, spandexes are all based on plastic.
You can actively see the micro-plastics being created: every time you wash and dry your clothes, plastic fibers are being shed from these clothes and ending up in waste water channels and landfills.
True to a degree. Still, I typically see tags listing fabric composition of clothing and am able to choose to wear e.g. near 100% cotton or wool. Also, at least a fabric is normally in use by the final consumer/wearer for some time.
The uses I listed are, sadly, completely hidden and are all in disposables.
Personally, I would not be opposed to a regulation that would mandate big red warning labels with plastic content breakdown on at least all of such disposable goods and accompanying paraphernalia that are not entirely void of plastic; or indeed a hefty “plastic tax”.
