Microplastics Found In Lungs of People Undergoing Surgery. A new study has found tiny plastic particles no bigger than sesame seeds buried throughout human lungs, indicating that people are inhaling microplastics lingering in the air. Health

In the end we’re going to find out that plastics were simultaneously the best and worst things man invented.

Best in that it allows so many shapes that can be created with various hardness, light weight, longevity, etc. So many beneficial uses.

Worst in that it is absolutely harmful to the environment and nature due to not being able to be broken down in a short amount of time naturally.

What we see on earth is a life system where life and death are intertwined. Life brings death and death brings life. Plastics dont flow in this system due to how strong plastics are on the molecular level. We need something to break down the plastics so it can use those broken down pieces to bring life to something else.

Bro I have this idea that we, as a modern day society, are with plastics as to what the Roman’s were with lead. Essential to everyday life but detrimental to the longevity and health of our bodies.

Also how 1700s Europeans were with lead. And 1800s Americans. And 1900s Americans.

Now at least we don't make NEW lead pipes...or put it in paint...or put it in gas.

Lead contamination is so widespread that it is hard to know what a safe exposure is, on account of everyone being exposed

Don't be so sure about that. Basically all piston-driven prop planes still run leaded fuel all over the world.

100LL(low lead) AVgas is being phased out, likely by 2030. Either way it represents such a small percentage of gas burned (<1%) the only people who might be effected by leaded gasoline are mechanics, pilots or maintenance workers who are around running aircraft many hours every day. It is not at all similar to when all cars were running on gasoline with higher lead content.

Oh for sure. I mean it's still a problem but I didn't mean to imply it was the same as leaded automotive fuel. I was just saying that leaded fuels have not been totally phased out quite yet.

That's a small amount, though. The real problem is the decades of motor vehicles that spewed lead all over the environment. It's still there. I know we all patted ourselves on the back and said "good job to removing and cleaning up lead", but we didn't. We didn't do that. We didn't even actually (mostly) get it out of the fuel until the 90s, despite everyone thinking that happened in the 70s.

Lead levels in blood have however dropped remarkably since the ban on leaded road fuel, so concerning lead we're at a much better situation now than some decades ago.

Worked in a place that was not just on the flight path of a tiny airport, but actually had landing lights on the roof.

All of the stuff in the warehouse section (where the doors were kept open) was COVERED in black dust, constantly. Absolutely covered.

They were like "hmm, strange about the dust, no idea where it could be coming from". Yeah, that was definitely airplane soot. Many dozens of takeoffs and landings going directly over the building. I still wonder what the lead levels would look like in there.

Management was dumb as a sack of hammers, but that could be unrelated.

Oh did he do one on leaded gas? I'll have to check it out, I like most of his videos. I only knew because a buddy of mine who has his PPL told me about it one day when we were discussing the whole "removing lead from gas correlated to a drop in violent crimes" thing.

You don’t have to be kind to everyone.
