Edit to note that this is apparently 78% of microplastics *from specific sources, including textiles and personal care products*, which is only 11% of total microplastics.

So about 8% of total microplastics is directly from car tires.

RT @jme_pew Turns out “microplastics” isn’t descriptive enough. We should be panicking about *tire dust.*

“Seventy-eight percent of ocean microplastics are synthetic tire rubber, according to a report by the Pew Charitable Trust.”

@capntransit all this time I'd been feeling guilty for wearing jeans with a little Lycra in the weave, thinking the ocean microplastics were coming from washing synthetic fabrics.

Now I can feel self-conscious about my butt guilt-free.

@Pxtl @capntransit Thanks for spreading this absolution
