New research reveals an unappreciated public health crisis: people living in slums in the developing world are increasingly burning the toxic plastic trash that surrounds their communities as a last-resort fuel to cook and heat their homes.
Burning Plastic Waste for Household Fuel Endangers Millions  - Inside Climate News
People in low-income urban communities in the Global South without access to reliable energy sources are burning the toxic plastic waste inundating their communities to cook and heat their homes.

Q How pervasive are micro and nanoplastics, really? A. Not yet known.

Sensible advice: ."..squabbles in science can... throw out common-sense policies that curtail plastic use... we do not know what the future of microplastics research holds. We will have to keep doing it to find out."

Interesting to see the Guardian's @dpcarrington.bsky.social weighing in on this. My take, as someone covering microplastics heavily for the past year (and currently sitting at a 200+ person conference with many of the scientists in question):

⚠️ A new study, based on information collected through a survey of 1,018 informants from cities in 26 countries in the Global South, finds that the use of waste plastics as fuel (for heat or cooking) by low-income households is much more prevalent than previously thought.

Microplastics interfere with photosynthesis in phytoplankton & impair zooplankton metabolism - both are central in ocean carbon cycling

Oceans absorb about 1/4 of CO2 released by human activity

Plastic pollution is no longer abstract.

Microplastics are now found in our brains, blood and breast milk — and across all parts of the planet.

On the Mongabay Newscast, Judith Enck explains why governments can’t wait, and how they can act now to cut plastic at the source.
Plastic pollution requires urgent action, says author Judith Enck

Plastic hasn’t just polluted the land and oceans. Research has found microplastics in cloud water, which are influencing how clouds form by acting as seeds for ice crystals, thereby accelerating the formation of storms and increasing their strength. #WetTribe #TidetotheOcean #MicroplasticMonday

Sciences like anthropology are so valuable because they provide refutations to "this is the way it always was, and thus the way it has to be" type assertions. Its very different to the science I do, but perhaps even more valuable.
honestly something i'm noticing is that whenever a midwit hack wants to make an empirical claim about "the way humanity is" without reading any social science they always just go to primatology

I see there’s a post about microplastics going around with a photo of drinking straws, so here is my semi-regular reminder that the 3 biggest sources of microplastics are tires (45%), synthetic clothing particles (35%) and paint (~10%).
Lay article attached:
One of the biggest microplastic pollution sources isn’t straws or grocery bags – it’s your tires
Every few years, the tires on your car wear thin and need to be replaced. But where does that lost tire material go? The answer, unfortunately, is often waterways, where the tiny microplastic particle...

The best way to reduce plastic waste is to use less plastic (including synthetic fibers) in the first place and support research into truly biodegradable plastics (that do not require toxic additives) for those applications for which plastics are truly the best material.

Cheap (subsidized) virgin #plastics are undercutting the market for recycled plastics in the EU, leading to the shuttering of numerous (mechanical) recycling plants. In response, the EU has announced additional checks and stricter rules on claims of recycled content in #plastic imported from abroad.

I wholeheartedly agree—though after laying out a good initial argument this paper takes a strange turn with the final two sentences that seems to undercut most of its own force.
