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.
It’s on all your outer wear and when it rains it goes straight into your local water system where you end up drinking it.
Also in fire suppressors.
