Our oceans have lost 50% of life in the last 40 years; 1/3 of marine mammals and sharks and others are at risk of extinction and close to 90% of the ocean has been damaged by humans.
I’ll say it again, we have nothing close to sustainable management.
Not trolling, and nothing personal but I pointed out an inaccuracy in a vapid and snarky comment with the level of detail it deserved.
The fallacy in your understanding of fisheries management, as you describe it, is that fisheries are not managed as a single global stock. Your argument is the equivalent of saying "all worldwide governments are terrible because some totaltarian despots exist".
There certainly are some historical failures and cautionary tales in fisheries management. But partially in response to those missteps, like the collapse of Atlantic cod fisheries in 1992, the implementation of science-based fisheries management have greatly improved. This isn't just an exercise in hypotheticals, where intensive management is applied, previously overfished stocks rebuild, or stocks are at target levels that can support sustained harvesting (https://www.pnas.org/content/117/4/2218).
Fisheries management works where applied, and there are absolutely examples of sustainably managed fisheries today - take skipjack tuna a cosmopolitan species that is not at risk of overexploitation. They can be harvested on a commercial scale with pole and line gear, one at a time with very low rates of bycatch. This isn't some fringe case either, skipjack make up the majority of global tuna harvest.
nobody brought up fisheries management specifically until this comment of yours. In fact the first mention of "sustainable management" was when you said "sustainable management of all sources of food." good information, but weird argumentation to say the least
Can't agree it is weird, the comment I replied to raised exclusively ocean-related examples to support their taking exception to the existence of sustainable management (of food production), I reckon management of capture fisheries is a pretty logical place to establish that examples of sustainable management do exist in response.
Also, to counter 'there's no sustainable management (of food production)' one only needs to establish that an example does exist, and an example is going to be within some specific niche of production. As a gift to HN, I chose to stay within my realm of expertise.
Finally, maybe it's just me but considering the broader context of the thread in which we were told we ought to stop fishing entirely and rely solely on plants for sustenence, I don't get the impression that the commenter had management of cereal grain agriculture in mind when they implied 'management' practices are inherently unsustainable.
That is incorrect.
