Some EU supermarkets used to have a circular glass system where products were brought in bulk, and only canned in glass inside the shop, sometimes by the customer. Bottles were then returned after use, washed locally and reused many times. This looked fairly efficient.

Restaurants and bars still have the same system here for e.g. Coca-Cola drinks, which come inside a glass bottle that has been reused several times. I'm not sure plastic is more efficient than reusing a glass bottle. Lots of yogurts are packaged in glass containers, and price seems average. I have also heard that plastic is rarely recycled, so it also sounds unsustainable from that perspective.

"Being there" can be harmful in and of itself. Blocking receptors, clogging up conduits, etc. As I understand it, this is why certain elemental metals are so toxic: They're big atoms that deposit in harmful places and can't be effectively filtered out.

Small amounts of mercury and aluminum have been shown to be safe in the bloodstream. The dose is the poison

Which is why you have to take care not to eat too much seafood

I agree with every point here, and they all make a lot of sense... yet most alcoholic beverages are shipped to the consumer in glass bottles, including even the cheapest beers.

I have seen some drinks shipped in plastic, so it is possible to do, I wonder if glass packaging is a 'premium' thing. Though, if they can do it for cheap beer, then I'm sure they can do it for non-alcoholic drinks on scale.

What is your evidence that microparticles from cotton are not also toxic?

They are ordinary, biodegradable, organic plant material, things to which our bodies are accustomed to for millions of years. You might as well ask whether grass is toxic.

The human body does not contain enzymes that digest cellulose. So how is this degradation to occur?

Fungal attack on woody biomass involves chemicals you do not want in your body. The attack involves extremely reactive hydroxyl radicals, for example.

Being accustomed to something doesn't mean the thing doesn't hurt us.

I am fairly convinced that this comment section is among the best demonstrations for "isolated demands for rigor" I have personally ever seen, especially paired with any comment section about an AI-related article When we are trying to predict the implications of unproven technologies on complex worldwide economies, there is talk of "obvious inevitability" When we express concerns that chemicals humanity recently sta…

Well, we've been exposed to microplastics for decades, but what does the evidence say? Afaict, not much.

We don't need RCTs, nor do we rely on them to make causal inferences about long term exposures, nor would an RCT be possible with microplastics.

But we need some converging lines of evidence before we go chicken little. What's the alternative?

I've seen and had alcohol in plastic. They generally seem to do fine.

But damn did it feel cheap in a bad way. Being cheap is obviously one of the reasons we use plastic containers, but the feeling associated with plastic alcohol is just plain irrationally bad.

What's the toxicity of microglass particulates?
