I’m going to take a different approach than most of the other comments here: you can’t. Microplastics are in the air and a large chunk of it comes from car tire residue. You’re breathing it, likely right now. Research is still in the early phases and we just don’t know how bad it is yet, both from the proliferation and the impact side of things.
Source is Breaking the Plastic Wave and Overview on the occurrence of microplastics in air.
“cis” isn’t an acronym, FYI. It’s just short for “cisgender” and doesn’t need to be capitalized. No shade intended at all, just wanted to let you know.
