Nice article by Ravleen Kaur on the health and environmental impacts of #plastic *production*. This again highlights why #plasticpollution cannot be treated as a waste or clean-up issue: it must be tackled at the source. india.mongabay.com/2025/09/comm...

UN politics won’t deliver an ambitious plastics treaty Negotiators again failed to finalize the text for a global plastics treaty in Geneva in August 2025. The talks exposed two harsh truths. Consensus on the treaty text, where no state formally objects, ...

A bloc of oil-producing states with powerful petrochemical interests is distorting scientific findings and opposing any controls on new plastics.

Preventing a weak treaty was a victory for those advocating strong, binding measures regulating plastic production.

In food history, we notice how super-refined foods--gelatin, vienna sausage, white bread--lose class and become horrifying once they become industrialized. Suddenly, fingermarks in bread dough demonstrate skill, not clumsiness.

Post-chatGPT, I'm feeling this about writing. Smoothness feels gross.

Microplastics Found Deep Inside Human Bones, Scientists Warn Microplastics are now so ubiquitous we're drinking, eating, and inhaling them.

Microplastics are now so ubiquitous we're drinking, eating, and inhaling them. As a result, they're showing up in our stool, placentas, reproductive organs, and brains. Now these particles, less than 5 mm in size, have been found deep within our bones.

#plastic #recycling #adana | Sedat GΓΌndoğdu | 10 comments This morning (21.09.2025), residents of Γ‡ukurova, Adana, woke up under a dark sky filled with toxic smoke. A fire broke out in an illegal #plastic waste depot located in KΓΌΓ§ΓΌkdikili. These facilities ...

Another #plastics recycling facility on fire, this one hosting waste "exported" by the UK to Turkey. A terrible case of #wastecolonialism and a huge health hazard to those downwind and ultimately, all of us, as many of the pollutants will enter the food chain. www.linkedin.com/posts/sedat-...

Plastics in the marine carbon cycle - Nature Sustainability Marine plastic pollution is a growing problem threatening ocean ecosystems. Now research explores how these plastics may be impacting the ocean’s ability to offset anthropogenic carbon emissions.

"...We are making & discarding so much plastic that it has become a substantial component of the global carbon cycle..." Aron Stubbins (The Plastics Center at Northeastern University) on Pang et al's piece on plastics & the marine carbon cycle in NatureSustainability

it's good...but that 7.5 bn could be better targeted. The pacific garbage patch is only a tiny % of the plastic entering the ocean. Targeting the source at rivers is far more important.

Microplastics are less than 5mm. Primary microplastics are pellets, microbeads, capsules, or fibers. Secondary microplastics are larger pieces of plastic that have broken apart when exposed to sunlight, salt, and wave action. #WetTribe #TidetotheOcean #Microplastics #Microfibers

Reminds me of one of my favorite quotes from a video game:

"Are all the accomplishments of humanity fated to be nothing more than a layer of broken plastic shards thinly strewn across a fossil bed, sandwiched between the Burgess Shale and an eon's worth of mud?"

Assume the digestion is complete, and the polymers are broken down to very basic molecules, such as CO2 or methane. That would address the #microplastic problem, but the carbon β€” which comes from fossil fuels β€” would still likely escape to the atmosphere.

That threat is not just the CO2 emissions generated through the refining of fossil fuels; the production of monomers, polymer resins, & final plastic products; & the incineration of plastics; but also the various toxic chemicals added to those polymers and the microplastics that they decompose into.
