I will now stop using laundry pods.
Even while acknowledging that their contribution to microplastics is small.
The major contributors to microplastics in the oceans:
Synthetic textiles
(They make me sweat unpleasantly, so I stay away from those, too),
Car tires
(why I bike: skinny tires, a lot less wear!)
City dust
(Guessing that includes the two above, plus house paint and such).
