  • Well, those distances use a nearby highway, and there are no bike lanes anywhere (let alone sidewalks). As mentioned earlier, being suicidal means I did use a bicycle anyway, and after a couple years I had a brain injury, was hit by cars twice and ended up with permanent injuries. So… yeah, I don’t recommend cycling (if you feel like being alive and able-bodied, anyway).

    What is also not mentioned is that the nearest supermarket is a shitty Walmart, the nearest park is very small and not really worth going to, and the bus is not a practical form of public transit here.

    I have to drive 20 - 30 minutes to actually get to stores, parks, or other places I would actually go to. I think that’s pretty good relative to most people, I live in a centralized location and most places are equidistant. I used to live in a nearby more rural town and I had to drive 45 - 60 minutes to get most places, and that was much worse.


  • I live in a suburb in the U.S.

    • To the nearest convenience store: 322m
    • To the nearest chain supermarket: 2.4km
    • To the bus stop: 2.6km
    • To the nearest park: 5.5km
    • To the nearest big supermarket: 6.1km
    • To the nearest library: 7.7km
    • To the nearest train station: N/A

    Notes:

    • The “convenience store” in my example is a gas station, technically you can buy lottery tickets, candy, cigarettes, beer, and a few things like that - but very limited inventory, it’s mostly for people buying gas. It’s also very unusual to have a gas station like this located basically in a suburban area, most places you would have to go much further to find one.
    • no sidewalks or safe passage, you walk on a dangerous road with ditches on either side to get to the convenience store.
    • the only public transit is a bus, it is used only by poor people, and it doesn’t cover the west half of the city (for example I was unable to use public transit to go to school)

    I have run to the park before despite being far away, but I think most people would (rightfully) think I was suicidal for doing so. A lot of the way to the park requires walking on dangerous streets where people drive fast around blind curves and where there is little to no shoulders to squeeze by if there are cars, most of the way has no sidewalks, and I have to cross busy roads where drivers are going 80+kmh.

    Owning a car here is considered a part of being an adult, people without a car are seen as childish or immature, and usually suspected of being drunks who have lost their license due to DUIs or felons who cannot have a driving license and aren’t allowed to leave the state. It is assumed everyone drives everywhere, alternatives are unthinkable to most people here.









  • Oh wow, yeah - the sample size is small but if I were playing devil’s advocate (which apparently I’m doing here, lol), while the correlation seems clear the cause could still be some other common root cause - maybe the same reason they have a diet heavy in plastics is separately why they had worse health outcomes, so it would be nice to reproduce this correlation and try to control for those kinds of differences. Just as an example of what I mean: perhaps the reason they have more plastic is because they ate more fast food, and fast-food happens to have more plastics in the food, but the causal mechanism for the worse health outcomes could come from the fast-food heavy diet, rather than just the presence of plastics in the plaque which happens to coincide with the worse diet. This is not meant to be proof it isn’t the plastics, I am just trying to show how hard it can be to move from demonstrated correlation to causal connections.

    Still, if they can find a causal mechanism that explains how the microplastics are playing a role, that will be huge. It certainly seems like good enough evidence to be wary of microplastics.

    Your comparison to cigarettes is apt, especially the way that the industry manipulated the public. I also agree that there is sufficient evidence to decrease microplastics, I just look forward to that causal mechanisms being discovered that demonstrate the ways they harm us.


  • So unless someone is trying to argue that microplastics found in the clog didn’t help contribute to the clog to any degree it’s clearly having a bad effect on the body.

    Yes, I would assume that the presence of the microplastics in the plaque is not contributing significantly to the accumulation of the plaque or the development of the heart disease, since it is the plaque accumulation that causes the heart disease and the presence of microplastics is more like the presence of other bioaccumulators in higher-trophic organisms (like vitamin B12, mercury, or strontium-90).

    I do agree this is like talking about the toxicity of the stainless steel of the knife found in someone’s heart - clearly the problem here isn’t the material of the knife and whether it is toxic, but the fact that someone was stabbed. Likewise, the problem is the accumulation of the plaque and the heart disease that follows - the focus on the microplastics is irrelevant except that it is concerning if we later find out microplastics are causing disease.

    The only reason I’m focusing on whether the microplastics are indeed toxic or not is because that is a big claim, and if found to be true would be really big news. It sounds like that hasn’t been demonstrated yet, though I want to look at the link zero_spelled_with_an_ecks sent, it looks like the article talks about leaching from microplastics that may have more clear health impacts.

    I don’t mean to be nit-picking, in university classes professors have discussed microplastics like in the context of agriculture and food-supply and my professors basically said the science is not out yet about what the effects of microplastics are, even if everyone felt they were probably bad there wasn’t evidence yet as to how they were bad. I couldn’t tell if the headline was implying there was a breakthrough in the science, and looking now it just seems like there hasn’t been one and it’s just more of the general sentiment that plastics are probably bad.


  • Right, but PFAS isn’t even plastic, it’s a chemical used as a coating to make things like take-out containers waterproof. PFAS is its own environmental catastrophe, but it doesn’t relate to whether microplastics are toxic.

    Plastic itself isn’t toxic, in fact plastic is biochemically inert (not a source, but further reading on Wikipedia). Various additives to plastic have been shown to be toxic, but those are less relevant to discussions of accumulating microplastics in the body.

    Some contexts would be more likely to have negative health impact from microplastics, like when there are larger particles of plastic in the air that factory workers get in their lungs, maybe those particles could cause mechanical damage to the lungs that lead to cancers or other conditions.

    That is speculative, and it shows we need more studies to find ways that microplastics impact health, but the title is a little misleading characterizing plastics as toxic in the context of microplastics in arterial plaque, since that is not demonstrated to pose a health risk (even if we all agree it is concerning and may pose some kind of health risk we aren’t yet aware of).







  • yeah, that makes sense in your context - canned squash isn’t so bad, definitely not worth making from scratch.

    I’m in a suburb where I have grown squash in my compost bin and gotten a harvest that lasted me a whole year, and that squash was some of the tastiest and had the most colorful of any squash I’ve had. The squash was also essentially free, a waste product, and in that context it seemed worth it (at least in some sense). However, it does take time and planning and a lot more work, and as you’re saying depending on who you’re baking for they may not appreciate it.
