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.
Someone mentioned PFAS, I would add regular old exhaust fumes. Terribly bad for you, terribly bad for the brain, effects linger and compound.
China did studies on it back before they went hard core renewables and electrical, turns out breathing fumes drops your IQ by so many points, and it takes more than 24 hours to kind of get back to normal, but if you whiff it again before that the timer resets.
I’m summarizing from memory, but that’s the gist of it.
Fuck cars, fuck fossil fuels.
