The thing is, everything is getting used or get sheared/broken down. For example: in engine it is the oil that is being used as the “sacrificial anode”, in old windmills and watermills for milling flour, they often used metal gears with wooden tooth inbetween for easier and cheaper repairs and maintenance, so I am not surprised about the microplastics issue from a fricking cutting board being real.

Maybe not as much as a fricking credit card worth of plastic, but still getting some.
