What does that look like today, pragmatically speaking?

asking, for all tasks shown to introduce large amounts of microplastics in our bodies and environment, "can we accomplish this task in a way that doesn't introduce microplastics in our bodies and environment"?

For example, using a reusable metal gourd instead of plastic water bottles for the task of 'portable hydration'.

and because this is Hacker News, I'll kindly welcome the comment: 'well actually metal gourds have some toxic substance in the lining that's worse than microplastics' and reply: ok, Cardboard bottles then. Or a gourd made of a sheep's bladder like back in the good ol' days, whatever they used back in the bronze age.
