Yeah, one can just "drink like a real adult", like the ones said to me that now want the plastic straws back...

Getting rid of plastic straws, but not cups and lids was such a stupid thing. There are substitutes for cups, but they cost more, so they weren't a good option for greenwashing.

If you're already minimizing seafood intake because of the lead content, you're already minimizing your personal impact of fishing net use. What we need to do is legislate the use of hemp nets. Hemp was the primary net maternal before the oil industry put their weight behind making hemp illegal under the guise of "The War On Drugs!" and made plastic/nylon nets the default.

That would be ideal, but each person has limited time and attention. Advocate for both, but put your efforts into figuring out how to change the thing with the larger impact.
