So people kind of knew asbestos was harmful wayyy before it mostly stopped being used in 1979 (USA). But, it was still used constantly in many industries and ended up everywhere. What do you think is an example of something we find out is DRASTICALLY harmful 10-50 years from now? My guess would be screen time.
That’s the other thing, too. It’s rare to be in a situation where you could inhale it. The only example I can think, which is also a rare situation, is if a vehicle that uses it is involved in some kind of accident and breaks the piece of carbon fiber. That could release it into the air causing you to breathe it in.
