Most fish are caught and some sea based farming efforts have been pretty terrible for the environment.
I reckon if you want to eat meat still you should mostly be eating chicken.
But favorably chicken that has seen the sun and real soil to pick in, not only on the way to the slaughterhouse.
And there is nothing inheritently wrong with fishing, it is just that the way it is usually done, is quite horrific. But there is somewhat certified ethical fishing. Or local fishermen.
Also like the sibling comment said, not really possible with our tech and knowledge. Lab grown meat would be the way to go to achieve it.
I imagine the meat would be pretty tasteless though.
What’s the plan once the oceans are messed up permanently?
At this moment, I think factory farmed chicken would have less impact on the environment.
When you are not overfishing and destroying the ground with bad trawling, where is the problem?
(But yes, it is a problem, that both is done)
The oceans warming is a separate problem.
And I like fish as well as chicken as well as beef. But I don't have to eat it every day.
I used to be pescatarian and my main reason for that was factory farming. Once reason I now eat meat is that it has become a lot easier to buy meat that has been well treated.
By virtually all metrics, intensive land-based animal farming is much harder on the environment. Also, in terms of animal welfare, its super sketchy even with animals labeled organic.
The misinformation around fish farming is absurd. I think people want to believe in the myth that commercial fishing is a couple guys in a wooden boat; when its actually a floating factory discarding up to half or more of what it kills.
There are many aquatic things I won't eat but mostly it is of the "wild fish" variety (overfishing, pollution, mercury, bycatch). I worked a single season as a fisheries observer in Alaska. The destruction was maddening.
I put wild fish in quotes because many times they are raised in a hatcheries then released into the wild. Which has ruined the gene pool of salmon in places that do this.
After a few years raising chickens at my home farm, I became pescatarian. I drew an arbitrary line at intelligence where I wouldn't eat anything as smart or smarter than a chicken.
Anyhow, avoiding farmed fish while eating land meat is really misinformed. I think the meat industry and commercial fishing industries have managed to completely misinform the American public (and a few well-meaning but misleading documentaries on the subject).
America doesn't not farm very many aquatic things besides oysters, trout and catfish. Which are all very very green industries. I like to bring these ones up in conversations about this topic.
I’m not saying we should eat “land meat”. I’m saying specifically chicken. I believe they are the most cost effective of the meats.
Of the farmed fish, did you single out trout and catfish because they are green, or has the industry in general improved?
I regularly eat pig despite a higher level of sentience. And despite having had far more interactions with pigs compared to Octopus.
Point being, we humans really are not rational with our food choices.
Overfishing aside, I guess you would most often find people that believe hunting /fishing for your food is more ethical than farming it
Nowadays, there are many more humans and domestic animals than wild terrestrial vertebrates, so hunting could not sustain any non-negligible fraction of the humans.
The modern methods of fishing are much too wasteful, so neither fishing has any future.
