At least broken glass doesn't stay sharp for long when exposed to the elements.
Why wouldn't it? Archaelogists find obsidian blades thousands of years old that still have an edge.

Nanoparticles of soot, magnetite, and other industrial atmospheric pollutants. https://www.sciencemag.org/news/2016/09/industrial-air-pollu... We already accept the impact of millions a year dying as a result of industrial pollution, especially from burning coal; we mostly shrug and move on. VOC’s, microplastic, nanoparticles such as TiO2, a lot of the crap in cosmetics, and probably a lot more.
>We already accept the impact of millions a year dying as a result of industrial pollution... We accept them because the mainstream narrative does not make a big issue of it. On the other side, we make a big deal when there is a measles death, calling for death of anti-vaxxers, because the mainstream narrative suggests so... In other words, the public, including the people here. is a bunch of morons who won't jump aw…
Measles...it's hard to make a case that the benefits of getting measles outweigh anything.

Yes? I don't know why people still use leaded solder in the first place? I only use lead free solder for my hobby projects, and it works fine.
Flows better, cracks less, doesn't grow whiskers. On every dimension other than safety it is by far the superior product. Noticeably so, even with practice and good JBC irons. I recently made the jump to tin, so the difference is fresh in my mind. I have a bench full of uwave equipment from the 80s on account of the price being 1/10 to 1/100 of newer equivalents -- how much of it would still be alive if they had used…
Tin ages poorly?
I was actually pondering something related today. I worry about my cats' paws getting glass in them. Because the pavement is full of tiny pieces of glass, even worse if someone breaks a bottle outside, they won't actually vacuum and clean it up, I guess wind can help a bit..but it's just shuffling the glass around. Glass doesn't decay on a human time scale. Which brought me to the grim fact that there are so many sub…
It doesn't oxidize.
I bet if you find any in the environment (excluding freshly broken glass on the street and that sort of thing) you'll find something where the sharpness of the edge has abraded away. If you're on a beach or near a creek, you'll possibly find something that looks dull and round and more like a pebble.

There are many mitigation strategies, but lead was a miracle cure, and it will take substantial time and effort to approach its efficacy, especially on the multi-decade timescale. My guess is that companies won't bother. Reliability beyond planned lifetime impacts their bottom line negatively, if at all.

From that article... >measles-mumps-rubella (MMR) vaccine, linked, by a sketchy and quickly refuted study, to autism. The supposed connection made a bigger impression than the refutation, and, while I didn’t actually know anyone who failed to get their children immunized for MMR, plenty of parents did refuse the shot; According to Andrew Wakefield, what he suggested was just that people use single, separate shots ins…
Andrew Wakefield is not a credible source on one single thing. Not only do you not have a source, I would want a secondary corroborating reliable source.
>5. The UK had a single dose measles vaccine program since 1967. The single rubella and mumps vaccines became available in the early seventies. The MMR vaccine was introduced in 1988. When parents started requesting the monovalent vaccines in increasing numbers, the DOH decided in August 1998 to withdraw their license. Those who could afford it crossed the Channel to get their children vaccinated or purchased the single vaccines at private clinics.

Also found this personal blog where a personal account of the same can be read.

But it is just a random page on the internet...
"Looking back, it seems insane. Bluntly put, we took a known poison and – for three quarters of a century – used it in machines that puffed it out in breathable form. Then we drove them millions of miles a day, all over the world, regularly dosing billions of people with the toxin." We are still doing just that, even though we are using milder poisons now.
What are the poisons of today that we allow? I general, from what I've gathered, we have been replacing substances that accumulates in nature with substances that breaks down over time. So for instance, we still do allow ozone but also watch the levels to ensure they aren't too high. I know there are issues with a lot of medication as it goes out in the sewage and there's still a big question mark on the safety of so…
