The average brain weighs 1300-1400 grams. If 0.5% of that is plastic by weight, your brain contains 6.5 - 7 grams of plastic. The average plastic credit card weighs 5 grams.

Jesus christ. I really thought that headline was exaggerated, but no, the brain samples they tested actually ended up being 0.5% plastic by weight. That's seriously disturbing, I really would have thought the blood-brain barrier would do a better job of keeping plastics out.
For every kilometer you drive, your tires shed 1 trillion plastic particles. 78% of microplastics in the ocean are from tires.
What are you suggesting? That I stop peeling out of every parking lot and doing sick doughnuts!?
What I'm saying is that we need to figure out to make tires out of some unholy bamboo/cheese composite.
What if the roads were rubber and the tires were asphalt?
