that's not really true. it is pretty well known that there are major detrimental effects of fish farms. of course we are still learning more and more, but we know at least something. salmon farms tend to take out good stuff from the ocean (fish) and return bad stuff (disease, waste, genetic changes, etc.).

there are species we know about going extinct due in part to commercial fishing. for example, the southern resident orcas have been struggling heavily due to commercial fishing, pollution, poisoning, capture, river damns, salmon farms, and more. there are very clear actionable things that can be done to save them, but none are even close to being acted upon. it is possible the population there has passed a point of no return such that that particular population will go extinct. they have struggled to even birth new orcas, and due to captures 30-50 years ago, they don't have the leadership they are used to. their behavior has already began to showcase how hard it is for them to even find salmon, as the normally tight knit pods have been seen breaking up to find salmon. there was a month in 2018 where almost none of the pod was seen for an entire month by whale watchers and scientists, an event that hasn't happened in decades or ever since they've started being observed.
