A bit more about the latter. Beyond organophosphates, the main other alternative is pyrethroids. These are highly toxic to aquatic life, and they're contact poisons to pollinators just landing on the surface (some anti-insect clothing is soaked in pyrethrin for its effect). Also, neonicotinoids are often applied as seed coatings (which are taken up and spread through the plant), which primarily just affect the plant itself. Alternatives are commonly foliar sprays. This means drift to non-target impacts as well, such as in your shelterbelts, private gardens, neighbors' homes, etc. You also have to use far higher total pesticide quantities with foliar sprays instead of systematics, which not only drift, but also wash off, etc. Neonicotinoids can impact floral visitors, with adverse sublethal impacts but e.g. large pyrethroid sprayings can cause massive immediate fatal knockdown events of whole populations of pollinators.

Regrettable substitution is a real thing. We need to factor it in better. And that applies to nanoplastics as well.

So, when we say microplastics, we really mainly mean nanoplastics - the stuff made from, say, drinking hot liquids from low-melting-point plastic containers. And yeah, they very much look like a problem. The strongest evidence is for cardiovascular disease. The 2024 NEJM study for example found that for patients with above-threshold levels of nanoplastics in cartoid artery plaque were 4,5x more likely to suffer from a heart attack. Neurologically, they cross the brain-blood barrier (and quite quickly). A 2023 study found that they cause alpha-synuclein to misfold and clump together, a halmark of Parkinsons and various kinds of dementia. broadly, they're associated with oxidative stress, neuroinflammation, protein aggregation, and neurotransmitter alterations. Oxidative stress is due to cells struggling to break down nanoplastics in them. They're also associated with immunotoxicity, inflammatory bowel disease, and reproductive dysfunction, including elevating inflammatory markers, impairing sperm quality, and modulating the tumor microenvironment. With respect to reproduction, they're also associated with epigenetic dysregulation, which can lead to heritable changes.

And here's one of the things that get me - and let me briefly switch to a different topic before looping back. All over, there's a rush to ban polycarbonate due to concerns over a degradation product (bisphenol-A), because it's (very weakly) estrogenic. But typical effective estrogenic activity from typical levels of bisphenol-A are orders of magnitude lower than that of phytoestrogens in food and supplements; bisphenol-A is just too rare to exert much impact. Phytoestrogens have way better PR than bisphenol-A, and people spend money buying products specifically to consume more of them. Some arguments against bisphenol-A focus on what type of estrogenic activity it can promote (more proliferative activity), but that falls apart given that different phytoestrogens span the whole gamut of types of activation. Earlier research arguing for an association with estrogen-linked cancer seems to have fallen apart in more recent studies. It does seem associated with PCOS, but it's hard to describe it as a causal association, because PCOS is associated with all sorts of things, including diet (which could change the exposure rate vs. non-PCOS populations) and significant hormonal changes (which could change the clearance rate of bisphenol-A vs. non-PCOS populations). In short, bisphenol-A from polycarbonate is not without concern, but the concern level seems like it should be much lower than with nanoplastics.

Why bring this up? Because polycarbonate is a low-nanoplastic-emitting material. It is a quite resilient, heat tolerant plastic, and thus - being much further from its glass transition temperature - is not particularly prone to shedding nanoplastics. By contrast, its replacements - polyethylene, polypropylene, polyethylene terephthate, etc - are highly associated with nanoplastic release, particularly with hot liquids. So by banning polycarbonate, we increase our exposure to nanoplastics, which are much better associated with actual harms. And unlike bisphenol-A, which is rapidly eliminated from the body, nanoplastics persist. You can't get rid of them. If some big harm is discovered with bisphenol-A that suddenly makes the risk picture seem much bigger than with nanoplastics, we can then just stop using it, and any further harm is gone. But we can't do that with nanoplastics.

People seriously need to think more about substitution risks when banning products. The EU in particular is bad about not considering it. Like, banning neonicotinoids and causing their replacement by organophosphates, etc isn't exactly some giant win. Whether it's a benefit to pollinators at all is very much up in the air, while it's almost certain that the substitution is more harmful for mammals such as ourselves (neonicotinoids have very low mammalian toxicity, unlike e.g. organophosphates, which are closely related to nerve agents).

Unions are a real-life strategy because they work. Divide-and-conquer is also a real-life strategy, because it works too.

Thus, I think the truth of your statement all depends on whether you look at this conflict between government and the the people, from the point of view of the attacker, vs the point of view of the defender.

But they used to. In the 1980s, nobody dared to say in public, that 17-year-old me should not be allowed to visit public (or even university) (or even medical) libraries. (Or if someone did, they were still very obscure and unpopular, little more than a glimmer in the left's eye.)

You don't get to pick and choose what people post (with some obvious exceptions like fraud or csam), while also claiming immunity for the stuff you couldn't or wouldn't.

Exactly, thanks for the excellent example. That's the kind of statement that nobody ever explains, but always presents as pure axiomatic dogma.

I do think that you might have revealed a clue in your unusual phrasing, though. You said "claiming immunity for the stuff you couldn't or wouldn't" but how can there ever be any possibility of liability there? If your computer denies someone else's request to publish something, what liability is there to be immune from?

are automakers responsible when someone breaks the speed limit and kills someone?

What's funny is that there's no such thing as "vicarious speeding" or "contributory reckless driving," but with copyright, there is. Analogously, sometimes the automaker is liable for drivers speeding!

But even so, Cox's behavior didn't fit contributory infringement.

The court just said T17 S501 is an ok law that they're not striking it down or anything like that, but it doesn't apply to this case!

A very good thing has happened.

It's illegal but laws aren't currently enforced, so I don't know why you're bringing the law up.

Let's perform a natural experiment: keep saying reappropriation is illegal, and then wait for the executive to do it anyway. Then watch to see if Congress gives a fuck, by impeaching the executive (or credibly threatening to impeach if the embezzled funds aren't returned in n hours).

My hypothesis is that Congress won't do anything about it, and is fine with whatever new powers that the president decides he wants.

What's your hypothesis?

Surprise: we're actually going to do that experiment. In fact, we started it last year.

It's not in society's interests, but it is in government's interests. Society and government are orthogonal teams who often conflict with each other. In the US, we spelled that out explicitly in the late 1700s, but docs go back at least as far as the Magna Carta.

Alas, "spelling out" government limitations isn't the same thing as believing limits are a good idea and enforcing them, as we're occasionally reminded. The Constitution is just ink on a page, until people give a fuck about it. And in America, the constitution is currently very unpopular. Society wants to surrender to government, or if it doesn't want that, it's sure acting like it wants that.

That's pretty neat!

The danger with using unallocated space, is that sometimes you might accidentally overwrite it. But if that happens, I guess it just means you need to figure out what your new size needs to be, make a new hidden volume, and then restore from backup. It's that last step that I never remember as a possibility, probably due to my horrible backup habits. ;-)
