Just 3D Printed A Chess Set

He may still ingest some microplastics. Yeah, we're all doing that now, but you could maybe not actively introduce yet another source to a young child?

I struggle with the "whataboutism" of plastics. Our clothes are plastic:

The hidden plastics in our clothes – and how to avoid them

Most people know that polyester trousers are made of plastic. But, from labels to threads and zippers, it is lurking in many less obvious places too. Here’s how to minimise the amount in your wardrobe – and the harm it causes

www.theguardian.com

I'm chatting on my plastic phone. At my computer typing on my plastic keyboard & mouse wearing my plastic glasses. All of my food comes plastc-wrapped...frozen tots, chilled chicken, dry snack bags. My car is covered in plastic. My online deliveries come in waterproof plastic bags or boxes filled with bubble warp or inflated plastic bags of air. I wear a plastic CPAP mask all night. Most of my cooking utensils are plastic. Ziploc & Rubbermaid are getting sued over their plastic claims:

Ziploc, Rubbermaid Sued for Microplastics Exposure. Are Plastic Food Containers Safe to Use?

Plastic storage products can leach microplastics into foods when frozen or microwaved. Here's how to limit your exposure.

Oddly enough, they found that glass bottles have MORE microplastics in them than plastic bottles:

Drinks in glass bottles have more microplastics than plastic bottles

A team of investigators at France's state food agency has discovered that some glass bottles have more microplastics in them than other containers, including those made of plastic. The "surprising finding" came about in tests carried out by the Anses Laboratory for Food Safety, whose researchers...

Fish have been swallowing microplastics since the 1950's:

Even salt & veggies aren't safe:

Even vegetarians can’t escape, according to a 2021 study. If the plastic is small enough, fruits and vegetables can absorb microplastics through their root systems and transfer those chemical bits to the plant’s stems, leaves, seeds and fruit.

Salt can be packed with plastic. A 2023 study found coarse Himalayan pink salt mined from the ground had the most microplastics, followed by black salt and marine salt. Sugar is also “an important route of human exposure to these micropollutants,” according to a 2022 study.

Rice:

Rice is also a culprit. A University of Queensland study found that for every 100 grams (1/2 cup) of rice people eat, they consume three to four milligrams of plastic — the number jumps to 13 milligrams per serving for instant rice. (You can reduce plastic contamination by up to 40% by washing rice, researchers said.

Meat:

All types of proteins contained microplastics

Breaded shrimp contained the most tiny plastics by far, at well over an average of 300 microplastic pieces per serving. Plant-based nuggets came in second, at under 100 pieces per serving, followed by chicken nuggets, pollock fish sticks, minimally processed White Gulf shrimp, fresh caught Key West pink shrimp and a plant-based fish-like stick.

Fruits & vegetables:

Apples and carrots were the most contaminated fruit and vegetable, respectively, with over 100,000 microplastics per gram. The smallest particles were found in carrots, while the largest pieces of plastic were found in lettuce, which was also the least contaminated vegetable.

We're all gonna look like Max Headroom soon:

Worrying about plastic may be ultimately pointless, but less plastic is better than more plastic, and frivolous bullshit is an easy place to cut it.

 

[Kaido]

less plastic is better than more plastic

I'd like to know the actual lifetime impact of plastic minimalism, i.e. will reducing plastic on a personal level REALLY have any long-term effect on my lifespan & health, given my daily environmental exposure? I mean, eating a hot dog shaves 36 minutes off your life (at this point I won't make it to retirement LOL). I went through a minimalism & zero-waste phase for awhile:

https://www.reddit.com/r/ZeroWaste/

But even glass mason jar lids have plastic linings to help them seal. Many cork products have plastic adhesives & composite fillers. Cardboard boxes are sealed with plastic tape & shipped with waterproof plastic labels. The amount of exposure we have on a daily basis is horrifying incredible lol.

 

[lxskllr]

Sure, but all those things *do* something. If you're gonna fuck shit up, and least get some real benefit from it. There's a lot of ways to trim around the periphery. The "problem" is they cost a little more than plastic, and in some cases, require more care and attention from the end user. But hey, I'll be dead soon enough anyway, so not my problem, right?

 

[Kaido]

and least get some real benefit from it.

That's what my question would be: is reduction actually worth it? Not just as an idealistic or morality exercise. Will not 3D printing add a year to my lifespan or reduce my statistical likelihood of cancer by any significant amount?

It gets funny in practice...I could go down to Whole Foods to use my reusable containers in the bulk section...which are stored in big, transparent plastic bins, which go into my plastic-coating-lined lids on the glass mason jars, then I touch my plastic credit card to pay for. Does that do anything actually meaningful in practice other than feeling better about using less plastic? Even video game controllers shed microplastics onto our skin:

https://www.reddit.com/r/gaming/comments/1jq17d/thats_not_dust_its_the_plastic_from_controller

Two of my main hobbies are 3D printing & sous-viding (vac-sealed plastic bags). The fun & convenience of both would be hard for me to give up, especially based on the statistics of what we'll get exposed to every day regardless of how hard we try:

How To Avoid Microplastics | Products You Should Ditch

In early 2024, scientists discovered an average of 240,000 pieces of tiny plastic in each liter of bottled water.

The study, published in the Proceedings of the National Academy of Sciences, added that 90% of the particles were nanoplastics, which previous research may have missed.

Again, not that reduction is a bad thing, but I'd like to know if it's really worth it. Like, we know that grilling meat literally raises your cancer risk, but I've made unfortunate peace with that fact:

https://www.uclahealth.org/news/article/grilling-meat-raises-cancer-risk-here-are-ways-lower-ithttps://www.uclahealth.org/news/article/grilling-meat-raises-cancer-risk-here-are-ways-lower-it

I figure:

1. We will all die someday
2. We should avoid major risks
3. We should feel good along the way (i.e. try not to poison ourselves) & enjoy life (luddite life optional!)
4. We should be good stewards of the environment

Relative perspective is crazy too...like, I spend waaaay too much time in hospitals due to health issues & it's always shocking to see the insane amount of plastic that just one floor goes through on a daily basis! By nature, most stuff is seal for saey & sanitization & is single-use:

https://www.plasticpollutioncoalition.org/blog/2025/2/20/excessive-plastic-in-healthcare-the-growing-crisis

There are entire organizations out there trying to offset the impact:

Add Bitcoin mining & A.I. burning up the world's energy...Bitcoin alone is now estimated to be up to 1% of the entire world's energy usage!

One Bitcoin transaction can spend up to 1,200 kWh of energy, which is equivalent to almost 100,000 VISA transactions.

I remember watching a short documentary on the Google homepage logo & how big of an environmental impact it literally had via electricity & bandwidth usage worldwide from being downloaded a zillion times a day. We live in crazy times!!

I struggle with the "whataboutism" of plastics. Our clothes are plastic:

That's not how you use "whataboutism".

"Whataboutism is a rhetorical tactic where someone responds to an accusation by making a counter-accusation instead of addressing the original claim. It often serves to distract from the issue at hand and can be seen as a logical fallacy."

We were literally talking about a 3D printed plastic item someone was planning to give to a child. There is no whataboutism at play, this is literally the thing being discussed. You are the one who posted the article discussing the food safety of 3D printed items that resulted in me making the post you replied to here. Yes, I'm aware plastics are everywhere, and no, I don't think it's a good thing, and I'm also not into letting perfection be the enemy of progress.

I'm not sure which fallacy it is that in case LOL. The idea being that we're already exposed to so much micro-plastic contamination...outside of feeling better about making a better choice, will it have any measurable impact long-term to use a 3D-printed toy on occasion vs. a store-bought plastic toy? I'm very much interested in practical data here. America's store shelves are kind of crazy...90% of kid's toys are made of plastic:

https://www.weforum.org/stories/2024/10/sustainable-toys-green-plastic-barbie-lego/

The latest research shows that today's babies have 15 times more microplastics in their bodies than adults:

Babies are full of microplastics, new research shows

When comparing stool samples between babies and adults, scientists found up to 15 times more microplastics.

www.euronews.com

The amount of exposure kids get is absolutely bonkers:

Playing with toy bricks can create microplastic pollution

Playing with plastic building bricks can generate significant amounts of microplastic and nanoplastic particles, potentially adding to indoor pollution and raising concerns about health risks.James Urquhart reports for Chemistry World.In short: Researchers found that plastic toy bricks release...

www.ehn.org

Researchers found that plastic toy bricks release thousands of micro- and nanoplastic particles during play.

Friction from assembling and disassembling the bricks causes these particles to form, especially at interlocking studs.

It's not just plastics that are a problem, either...many wooden toys are actually composite wood, which sometimes contains formaldehyde. Toxin control in toys is a real mess:

Beyond Lead: Toxins in Toys

You need to look out for more than just lead. Here is your guide to avoiding to toxins in children's toys.

www.greenamerica.org

On the contrary, the CPSC is “entirely reactive,” says Ruth Ann Norton, the former executive director of the Coalition to End Childhood Lead Poisoning (CECLP, part of the Green & Healthy Homes Initiative). Once a toy is already on store shelves, toy manufacturers are required to report to the CPSC if it causes any injuries or deaths, and consumers may submit reports, as well. The government’s current recall mechanism is exclusively “complaint driven,” explains Norton: the CPSC collects reports and may issue a recall of a toy it deems unsafe.

Both plastic AND paper straws are bad as well:

Why Paper Straws Are Bad...And Plastic Straws Are, Too!

Paper straws contain PFAS, while plastic draws can leach microplastics into drinks. Silicone and stainless steel are the healthiest straw materials. Don't drink plastic in hot water.

Plastic, silicone, and latex baby pacifiers all have shredding issues:

Nanoplastics released from daily used silicone and latex products during mechanical breakdown - PubMed

Waste of polymer products, especially plastics, in nature has become a problem that caught the awareness of the general public during the last decade. The macro- and micro polymers in nature will be broken down by naturally occurring events such as mechanical wear and ultra-violet (UV) radiation...

My cousin works in plastic recycling...this stuff is just the tip of iceberg. One of the craziest statistics is that car tires account for 78% of ocean microplastics:

A three-year study done in the UK finds that a car’s four tires churn out one trillion particles for every kilometer driven.
