Good news is tuna is not the only form of seafood you can eat! Perhaps you can try channeling that outrage into real tangible activism, any minute now.
Do you think the problem will go away over time? Are you OK with having fewer things that you can eat without poisoning yourself? Do you realize we only have so many reservoirs from which calories can come from?
Why do you accuse me of being against addressing these issues? I am merely pointing out these are not existential crises because there is currently no evidence supporting such claims. It may change in the future, but until then I'm not jumping on this ship.
Ultraprocessed foods are already poison and most of us, probably including you, are consuming them regularly. Are you OK with that? And what is this talk about caloric reservoirs? Humans 8000 years ago had far fewer options and they still survived long enough to pass cultural lineages down to us. Most of your "caloric reservoirs" did not exist before the 20th century because the science and industry that created them did not exist.
Compared with the other examples you gave, I think one of the differences with micro- and nanoplastic and their growing bioaccumulation, is that if/when we discover that some level of concentration of it causes noticeable issues, it will be very hard to reverse, and it will be globally abundant (i.e. throughout the entire food chain). We'll be stuck with the problem for a very very long time.
It's not like we'll be able to just outlaw it and be done with the issue after a few years. So for this specific polluant, it feels right that we should be cautious and look for solutions as quickly as we can.
Humans 8000 years ago got their food from an environment that wasn't contaminated with ubiquitous, unnaturally occurring, forever chemicals.
Ultra processed foods are a problem and likely contributing to the plastic problem. I do what I can to reduce my reliance on both. Yet the solution won't be the few educated among us stopping ourselves. It must be regulated collectively or we'll remain in a prisoners dilemma as the pollutants accumulate.
