On an unrelated notes, a huge fraction of oceanic microplastics is from car tyres. Driving is a number one source of oceanic microplastic.
Car tyres are also significant contributors to terrestial microplastics and particulate matter!
Since this is a science community, can I ask what studies directly link these microplastics to the specific adverse affects?
I see a lot of "BPA microplastics are hormone disruptors" and "microplastics found in placentas!" Etc ... ok, but are they the same microplastics in these studies?
It sounds like when everyone puts scarequotes around "chemicals"...
Come on, let's not doubt that eating car tires is unhealthy.
I breath a lot of car tires when i walk to work...
I never made any claims concerning effects.
And bad news: electric cars, being heavier, emit more microplastics.
tbf they are only heavier because they are making them SUVs instead of coupes or sedans and trying to convince people that a 150 mile range isnt long enough for them as if they wont just plug it back in when they get home or as if they actually commute 75 miles each way. God forbid they have to wait for it to charge. Electric vehicles have the potential to be the same weight or lighter but car companies all suck.
Yeah, if they built cars people don't want with batteries smaller than people want to buy, the wheels could just be as bad as normal cars.
If everyone had switched to driving corollas and civics in the year 1990, we would have less micro plastics and a way cooler environment but... people hate each other and don't give a fuck.
