From the article: >Rubber is also considered plastic, both natural (isoprene) and synthetic (styrene butadiene).
Definitely not what comes to mind when I think of plastics. I usually hear Bakelite quoted as the first invented plastic.

#32On the front page of HN at the exact same time, we have two different articles on this topic. One says that most ocean plastic comes from ships, the other says car tires. Clearly they're both accurate.

This hasn't been the case since the early 80s. Edit: Yes, you can probably find some no-name pads with asbestos if you look hard. Nobody is selling them knowingly in the US or EU.

They don't get purchased by the auto parts stores and big parts suppliers that supply the shops that change most of the countries brakes. They get sold to impor…
Ford was shipping cars with asbestos brakes in 1993. Asbestos brakes are still readily available on the aftermarket. Brake pads since 2015 sold in California and Washington must have less than 0.1% asbestos by weight (it's unclear to me if that's asbestos alone, or asbestos and other heavy metals like cadmium or mercury). Since the ban was put into place in 2015, you can reasonably infer a) that there were brake pads…

(DISCLAIMER: I am hoping we can discuss this from a purely intellectual perspective and not bring ideology into it) I have always postulated that the increase of estrogenic compounds may have some impact on what seems to be an utter surge of reported cases of gender dysphoria amongst others other disorders that typically arise when you mess with hormonal/endocrine systems. Has there been any scientific research done…
My "intellectual perspective" on this theory that you just made up is that you just made it up. Have a nice day.
