Biggest sources:
- 7.6 Mt from macro plastics breaking down
- 1.3 Mt from paint
- 1.0 Mt from tyres
10-40 Mt released into environment/year, and increasing.
I’m kinda surprised that more comes from paint than tires.
I think it depends on measure, if im not mistaken, by weight arohnd 50% of microplastics are tire dust.
Also depends on where you’re measuring. They make up a ton of the plastics in stormwater runoff for example. Sometimes up to 95% from what I found. And that stormwater often ends up in our drinking water.
Still both from automobile infrastructure. /c/fuckcars bleeding into every Lemmy…
You only think that way because the material for a tire is all in one place and easy to see.
Paint on the other hand is effectively invisible when we ‘inventory’ a space mentally.
So a tire in the middle of your living room seems like a lot of rubber but all the paint over every inch of the wall in the same room doesnt, even if the room is big enough for the paint to fill the volume of the tire.
Maybe global warming will melt all the microplastics into one big macroplastic and that problem will be 100% solved.
A race to see what will kill the most of us first. The plastic or anthropogenic climate change.
Don’t forget Antimicrobial resistance (AMR)!
Plastic will probably only make us infertile while climate change will kill us AND already stop us from reproducing (or do you feel a kid born today has a good perspective on it’s future?).
I fucking hate lemmy now, you are just reddit with a sense of undeserved elitism.
This is a serious as fuck problem and all that anyone replies with are jokes and shitposts.
This is fucking /c/science, not /c/sciencememes
But none of you care especially the mods, so I’m just blocking every one of you.
edit: There’s an entire subthread here that is nothing but masturbation jokes, which of course the mods ignore.
Fuck lemmy and its shitstain mod team same as the reddit mods but with worse hygiene. At least on reddit they keep /r/science clean
People having a laugh isn’t the problem.
There is a real problem with the thread format of social media however.
My proof is I can’t find the “in this discussion relevant” thread of masturbation jokes because time has moved on and so did the discussion. [Edit: your comment is only 1h old, so not sure whats up]
We need a much better way to organize our speech and discussions because a single scroll page sorted by time, or contextless votes ain’t doing it.
I actually noticed that some of my comments are reacted very different towards depending on the time of day, what side of planet earth is awake at the time.
There is an argument to be had that certain troll farms love to drown discussions in shitposts and maybe we should be more mindful of the patterns.
But to say we should crack down on any form of jokes, which are an important part of our human expression that goes too far, thats what i disliked about r/science
I’m so glad blocks are free.
Over 80% of microolastic production coming from macro plastic breakdown feels pretty bleak.
Plastics industry: “See?! We told you plastic decomposes and doesn’t just stay in landfills forever. Happy now?”
I am not happy now.

Rally?
WTF do we need plastic-coated fertilisers for?
to grow plastic infused plants, of course
Now sit down and eat your plasti-corn. There are children in other countries that have to eat normal corn.
Controlled Release Fertilizers (CRF) are coated with a tiny layer of polymer which allow to release nutrients in a very timely and targeted way to various crops (trees, flowers, some cash crops) and used in closed environments such as potting plants or greenhouses.
So it has its use. Guess we’ll need to find an alternative to using polymers now (among a ton of other work).
Or several trillion very small problems.
We’re all trillionaires! 🎉

Studies have identified some of the main sources of microplastics as:
- plastic-coated fertilisers
- plastic film used as mulch in agriculture
WTF?
- plastics recycling.
Uuuuh…
Plastic was never meant to be recycled.
So, what you’re telling us is, they’ve been lying for decades?
Yup passing on the responsibility from the manufacturer to the consumer
- plastic film used as mulch in agriculture
Wtf. Where and why?!
It’s the black plastic bag material that people used to cover their soil and poke holes through for their crops.
I never thought it was called plastic mulch though.
It serves the same purpose as actual mulch, which is blocking out weeds
Yes, but mulch has the meaning of ground up wood, so I think most people would think it was ground up plastics.
If it was ground up plastic it would probably just get carried off by the wind.
Or plastic greenhouses
Like, everywhere?

Have you seen the process used in plastic recycling? The plastic is literally triturated into tiny bits before being heated up for the next stages.
Edit: why the downvotes? I’m just trying to give some context on why plastic recycling is a great source of microplastics
Yep
I find little shards of plastic in the vegetables from the supplier at work quite often. Sometimes I plate a dish and spot a bit of blue where it shouldn’t be.
There are many reasons we are screwed as a species. There’s pretty much nothing I can do about it, unfortunately.
Rather than take a defeatist veiw from this line if thinking, it will do well for your mental health to first spend more time, energy and thoughts on things you can control. Not just things related to environmentalism, but broadly reduce energy, engagement and focus from the things you don’t have significant control over and direct them to those things you do have control. It’s good to get a broad picture and observe the world around you outside of your control in small doses, but it’s easy to over indulge in an unfocused survey of problems in the world, especially on social media. (I include Lemmy communities in the social media category).
Furthermore, when you do engage with these problems, do so with more narrow focus and in more depth with an eye towards understanding the level of impact the problem has and what organizations or policy positions you can support to amplify your limited influence over the issues that causee the problem. In this way you can mitigate the feelings of helplessness and sense of there being many existential and imminent problems you need to contend with but cannot remedy. You can turn seemingly untouchable solutions into real possibilities without overwhelming your emotional capacity by working with others.
I’ll go jerk off for a bit, maybe it’ll be better by the time I m done
Now you’re speaking my language, come and shake my hand… actually, nevermind.
Not much is going to get better in 12 seconds.
So what does it do? Cancer?
It’s making men infertile. theres even a shortage of viable sperm today around the world
Ok, that’s one positive at least.
In regards to humans, progress is being made. In coming years, expect greater clarity about effects on our bodies such as:
- inflammation
- oxidative stress (an imbalance of free radicals and antioxidants that damages cells)
- immune responses
- genotoxicity – damage to the genetic information in a cell that causes mutations, which can lead to cancer.
TL;DR yes, cancer. It also fucks with wildlife (blocking intestines, giving off poison)
Good chance it probably is, possibly increase chance for asthma, chance for heart attack, another is it probably makes us infertile probably a good thing depending how you think of it.
Is this stuff you know or are you guessing?
Mostly guess though I think remember reading some of it. Here are the links if your interested.

Disclaimer not a doctor, just some random guy in the internet.
And yet doctors insist I’m not getting enough fiber!
Can’t we just inject ourselves with plastic eating bacteria or something?
We just need to turn up the UV lights voltage and melt the plastic out. Is that something we could look into?
We are the plastic eating bacteria.
If we knew of bacteria that cleanly ate plastic, we probably wouldn’t be riddled with micro plastics 😉
We know of them and are working on making them more efficient
Those are Ideonella, and the byproducts are still toxic tu humans. Wouldn’t work.
Out of curiosotiy where would something like 3D printing be placed?
While a problem yes, miniscule compared to industrial waste
Not significantly contributing to the global problem, but you might inhale some. Don’t sand your prints for sure.
Or wear a respirator while you sand…
PLA I think just breaks down into lactic acid eventually, but the ABS probably isnt so good
It only breaks down under industrial environments. It’s not as “biodegradable” as claimed. I use PETG because I can recycle it with normal plastics recycling.
It breaks down in high heat, high water environments, aka thermophilic composting. This makes it ideal for agricultural and food waste. You’re right though it doesn’t recycle well.
Pretty bad, especially with people sanding down productions and stuff.
