Thing is- We’re only now starting to realize how bad plastics really are, because we only recently acquired the tech to measure this. Unexplained fertility decline in the last 40 years? Probably plastic. They found that humans had 3x higher concentration of plastics in their testicles than their pet dogs, and that pet-dogs have a dose-dependent reduction in viable sperm count inversely correlated with the plastic concentration. Have a plaque in your blood vessel body with high plastic concentration? Since this year we know it has a 4x (!!!) increase in a new heart infarct in the next year compared to when there is less plastic. It’s starting to show that it is really bad, and it’s virtually everywhere in our body, most likely causing a ton of issues.

>Unexplained fertility decline in the last 40 years? That's why human population has nearly doubled in last 40 years?

  No, look at this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6455044/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6455044/ Decreased sperm count in the west. Could be due to a variety of factors. But tie it together to microplastics: https://pubmed.ncbi.nlm.nih.gov/38745431/ https://pubmed.ncbi.nlm.nih.gov/38745431/ And you got an interesting result.

Unexplained fertility decline in the last 40 years? The most common plastics have been in wide use for nearly a century. It's not "unexplained"; the fetility decline is a product of many variables that include diet and lifestyle changes, and especially as it correlates with population growth, this could be another feedback loop. Pointing to one of the most widespread materials which have been in use for much longer is nothing but fearmongering. Might as well ascribe the "unexplained life expectancy increase" to plastics too. /s and that pet-dogs have a dose-dependent reduction in viable sperm count inversely correlated with the plastic concentration Correlation or causation? Or just a variant of the old "IN MICE!"? Add that to the widespread phenomenon of p-hacking and a lot of this "research" is just politicised junk optimised for engagement rather than truth.

We're just starting to learn HOW bad they are.
