Airborne plastic levels shock researchers (chronic DEHP/DiNP/DEHT exposure)

Tobacco companies had a very very weak argument that people born after a specific date used it on purpose (after the warnings were required on the product). Before that date, people believed it was safe due to ads.
But plastic people have no such argument. Health issues are yet to be fully confirmed. But after about 50 years of plastic being everywhere in the environment, we see alarming increases in many health issues among the young. The young have been exposed to plastics since conception.
To me, that is a rather big coincidence.
Are they related ? Only more research will tell, but everyone now has mirco-plastics in their systems.
Seems this is like the mercury build up that happen a long time ago. Eat organisms with micro-plastic in their system, it builds up in your system.
Also a domestic plastic tax - by making plastic less cheap (perhaps have it go up 10% every year in perpetuity) eventually there will be incentives to find natural alternatives (paper, bamboo, woods, etc).
It makes no sense to me to claim the most productive country in all of history, with our AI and everything, couldn't replace plastic. It's the same thing people said about oil 50 years ago.
Nobody is claiming it cannot be done but I believe its very valid to point out that it is not a no brainer and the implications on the global economy may be quite severe. Again not a defense of plastic but more that I think its more complicated than people make it out to be.
Yes, things would be more expensive, but we have a choice, Health or Plastic. If you factor in the cost of healthcare, then the extra expense may be a wash. It is just a matter of who pays.
The most pressing example is fast fashion. The clothes are too cheap, incentivising use-and-bin behavior, and they also don't last because they're cheap synthetics. Cotton is relatively more expensive, but at the very least lasts longer. The race to the bottom must be halted.
- Get serious about plastic recycling, maybe even a cash deposit scheme like glass bottles or aluminium cans in some places.
- Build/grow stuff closer to where it is sold, instead of halfway across the world, so less plastic (and fuel) is needed in transport both for finished products and supplies. This has the added benefit of introducing supply chain resilience, decreasing foreign dependence, and supporting local economies.
- Enable local food markets and street food vendors. Get rid of laws that make it difficult for food trucks or food streeth vendors to operate. Make operating a restaurant and/or selling food cheap and easy. Have your food JIT instead of needing to store it using plastic. Milk used to be delivered and consumed without plastic involved at all.
- Go back to using wood or metal instead of plastic in many items. This will make them stronger and more durable.
- Use paper or wood instead of plastic. Bring back paper grocery bags. Wood is renewable, wood products are biodegradable.
For example, I saw here on HN that micro-plastics were found in Human's brains. Also we have see a rise in Dementia and Alzheimers over the past decades. Again a bit of a coincidence to me, but makes you wonder.
Personally I think plastics is not the only cause, but I think it is one more thing to tack on to the environmental damage we have cased over the decades. And that damage is now getting to the point that have real health consequences, especially to the young.
Highlights
* Silicone wristbands were used to quantify exposure across two different cohorts.
* Human exposure to ortho-phthalates and non-ortho-phthalate plasticizers is ubiquitous.
* DiNP, DEHP, and DEHT accounted for 94–97% of human exposure.
* Our findings raise concerns about chronic DEHP/DiNP/DEHT exposure in urban areas.

Tons of food/kitchen products are made of silicone and touted as food safe. However, I always find that silicone kitchen products accumulate smells and then transfer these odors to the food, so I abhor them. This seems to confirm that mechanism.
