We’ve been washing polyester clothing and sheets for how long prior to microplastics being on the radar? Was water treatment filtering for it? Is it now?
Forget straws. We WEAR plastic.
How is most food irrigation accomplished? Through plastic. Drip irrigation in homesteading: plastic. Your “chemical free” homegrown veggie starts in those peat pucks: plastic mesh in plastic trays under plastic domes.
Need medical care? Septic? Dehydrated? Here’s a plastic and nylon catheter to the vein so we can drain fluids in a plastic bag through a plastic tube, right into your veins. And we will flush that IV with saline stored in plastic syringes each and every time. IV antibiotic? In a plastic bag.
My point is, at this point, we are and have been marinating in plastic, inside and out, for our basic essentials: food, sleep, hygiene, clothing, medicine. Of course it’s in the fish.
