I thought this was known for a long time already

Something I'm still waiting for data on: is there a difference between different plastic types when it comes to micro plastic concerns? Rubber is mostly isoprene which does degrade naturally to an extent. Other shit like ethylene, styrene, vinyl chloride etc all have wildly different properties and varying rates and modes of degradation.

Yet again "Fuck cars" and fuck the pedo-petrochem billionaires who've poisoned this planet by lobbying for the infrastructure to be everywhere.

I must be just dumb but how come it's microplastic when it's rubber?
