About a fifth of the world’s annual wild fish catch, amounting to about 18m tonnes of wild fish a year, is used to make fishmeal and fish oil, of which about 70% goes to fish farms
Among other environment impacts too. All kinds of fish farms dumps lage amounts of waste into the environment
For a world annual shrimp production [in fish farms] of around 5 million tons, 5.5 million tons of organic matter, 360,000 tons of nitrogen, and 125,000 tons of phosphorous are annually discharged to the environment
I love how capitalism always manages to make things worse when it claims to make them better. People keep selling the grift of capitalism solving problems caused by capitalism.
How in the actual fuck is selfishness going to lower selfishness? Checkmate liberals
What's the ROI? If 15% of wild caught fish are used to support fish farms that produce twice as much, it's not as obviously a bad thing. There'd need to be another food source though.
Going to almost certainly be less than 1. Moving further up the food chain results in energy losses. Those fish are going to use energy for their own body and such
Moreover there's high mortality rates inside of fish farms for fish themselves. From the linked earlier article
Fish mortality has more than quadrupled, from 3% in 2002 to about 13.5% in 2019, in Scottish salmon farms alone. About a fifth of these deaths are recorded as being due to sea lice infestations, but about two thirds are unaccounted for so the real mortality owing to sea lice – which feed on salmon skin and mucus, effectively eating the fish alive – could be much higher.

For sure, which is why I said "another food source would be needed." I had in mind something like the wild-caught fish being processed into something useful as part of a more efficient food chain, e.g. combined with efficiently-farmed plant material.
Moreover there’s high mortality rates inside of fish farms for fish themselves.
I don't have any context on the other pros and cons of fish farming, so definitely not arguing whether they're a net positive or not.

This version is implying that the soldier caption is doing nothing to protect the kid caption
Lay the blame on politicians denying climate change and large corporations with next to no obligation to operate in an environmentally friendly way. Laying the blame on average people living average lives, most of whom are just barely scraping by, is just defending the rich and powerful so that they can pass the buck on to the rest of us like they always do.
