Perhaps nanoplastics will do that first. As of 2024, from autopsies of many people, the median level of plastic in the human brain was 0.5% by weight. Numbers were higher for dementia suffering patients. This 0.5% by weight is equivalent to 7 grams, or the weight of a plastic spoon or fork. Crazy stuff... As AI advances to be more humanlike, humans degrade to become more plastic-like. Its like we literally are sticking a fork into our brains. How many forks before we die?? From autopsies on people who died in 2024, the plastic level in the brain was 50% higher than that measured in 2016, only 8 years previously. Global plastic production has increased exponentially from 1 to 2 million tons in 1950 to over 400 million tons in 2023, and production is doubling every 10 to 15 years. It takes time for a plastic water bottle floating in the ocean to be broken up into nanoplastics. Clearly, the nanoplastics we find today are likely derived from plastics produced sometime between 1950 and 1990 or so, so breakdown is certainly between 35 and 75 years. So there is a huge lag to this problem, and we will have enormous suffering in the future.

Article from the Ethicalist: Our Brains Are Now 99.5% Human—And 0.5% Plastic Human brain samples contain an entire spoon’s worth of nanoplastics, study says by Anthea Ayache, February 11, 2025 https://theethicalist.com/our-brains-are-now-99-5-human-and-0-5-plastic/ Researchers at the University of New Mexico have discovered substantial amounts of microplastics – tiny plastic particles less than 5 millimeters in size—in human brain tissue, with concentrations far exceeding levels found in other organs. The study published in Nature Medicine that analyzed the brains from 52 deceased individuals, discovered that the average sample contained approximately 7 grams of microplastics, equivalent to the weight of a plastic spoon. ‘Compared to autopsy brain samples from 2016, that’s about 50 per cent higher. That would mean that our brains today are 99.5 per cent brain and the rest is plastic.’ Professor Matthew Campen, University of New Mexico ‘I have yet to encounter a single human being who says, “There’s a bunch of plastic in my brain and I’m totally cool with that.”‘ Professor Matthew Campen, University of New Mexico From Meat to Our Brains While microplastics can be ingested, inhaled, or absorbed through the skin, scientists suspect that food, particularly meat, is the primary source of exposure. Irrigating fields with plastic-contaminated water likely leads to the buildup of plastics in crops, which are then consumed by livestock, allowing microplastics to accumulate in animal tissue. 1 liter of bottled water contained an average of 240,000 plastic particles from seven types of plastics. Some 90 per cent of those were nanoplastics meaning the vast majority of plastic contamination in bottled water is at a size invisible to the naked eye. I asked many more questions to try and find out how serious this threat is to human existence. 1) What is the mass of nanoplastics in the human brain? 2) How does the measured mass of nanoplastics compare to other organ contaminations? 3) What are the challenges in accurately measuring nanoplastics' mass in tissues? https://www.perplexity.ai/search/what-is-the-mass-of-nanoplasti-foRpSb4NQLu0GtHB_AlhRQ 4) How long does it take a plastic water bottle to break down into nanoplastics in the environment? Where is most of this break down occurring? 5) When was plastic invented? https://www.perplexity.ai/search/how-long-does-it-take-a-plasti-E7RcRPDVTZWTr3iiLtRLtA 6) When did plastic production worldwide expand greatly? 7) Please estimate the production years for plastics that have broken down into nanoparticles by 2016 and by 2024. https://www.perplexity.ai/search/when-was-plastic-invented-Zd4LdmgqQSKZB5JLwrIoag 8) Please show me data for global plastic production for the main types of plastics, and for the total. 9) Please show me plots over time for global plastic production for the main types of plastics, and for the total. 10) Yes, please create the visualizations. https://www.perplexity.ai/search/please-show-me-data-for-global-9UovVx6DSsqhAYNbI5rr4w?2=i&1=i 11) What harm does 0.5% by weight do microplastics and nanoplastics cause to the human brain? 12) What percentage by weight of microplastics and nanoplastics in the human brain will kill the person? 13) What is your best guess? 14) Can nanoplastics cross the blood-brain barrier and cause neurotoxicity? https://www.perplexity.ai/search/what-harm-does-0-5-by-weight-d-bv2UOYksRImaFM6f2AToCw Please donate to http://PaulBeckwith.net to support my research and videos connecting the dots on abrupt climate system mayhem. https://bit.ly/4504Bdv
