I'd be in favour of removing meat subsidies. If the 'true' price of steak or a burger was ten times higher people would eat it for special occasions and not every day with every meal. It's telling and hypocritical how many meat eating 'libertarians' are in favour of government handouts to preserve their food eating habits rather than letting the market do it's work. I'm a meat eater but I'll concede that those subsid…

Can you give an example of a 'meat subsidy'? I'm unaware of any.

I suspect that in 50 years, few people will be eating any seafood that isn't cultivated (aquaculture). Not out of choice, and not because of changing cultural values (it is tasty, after all). But because there's just none left. Saw a headline on reddit the other day, $800,000 for a single bluefin tuna. Granted, it was large (over 500 lbs), but you don't hold auctions with winning bids approaching a million dollars on…

Even now, I thought most tuna were farmed. There are certainly lots of large farms in the Mediterranean.

I watched a documentary years ago about jellyfish invading Japan. Basically, the jellyfish population was exploding because the fish didn't exist to eat the baby jellyfish and keep them under control. The Japanese fishermen were furious that they kept catching jellyfish, rather than the fish that they wanted. They were the cause of their own suffering. Sounds like things haven't changed... I hesitate to think that Ja…

They could start eating jellyfish to pick up the slack.

Yes, that is the second half of the documentary. They were trying to come up with delicious recipes to take advantage of the situation. I don't imagine I would like to eat jellyfish either, but I would certainly give it a try.

https://en.wikipedia.org/wiki/Passenger_pigeon Passenger pigeons were hunted by Native Americans, but hunting intensified after the arrival of Europeans, particularly in the 19th century. Pigeon meat was commercialized as cheap food, resulting in hunting on a massive scale for many decades. There were several other factors contributing to the decline and subsequent extinction of the species, including shrinking of th…

That's not how fishing works. After some threshold growing fish in aquaculture becomes cheaper than fishing, and things get back in balance. Otherwise, salmon would've been extinct by now.

Tuna and herring are not grown en masse in aquaculture... yet. That will change.

What on earth does beef have to do with this? If anything, people eating more beef might consume less fish. Cattle populations are not collapsing.

Fish management doesn't really require global cooperation. It does require some sacrifice. Where I live 100 years ago herring spawn covered nearly every shoreline. I live in an archipelago so there is a lot of coastline. Now there are sporadic patches of herring spawn. The herring fishery is a multi million dollar industry. Herring is also the base of the larger fin-fish population. We can't harvest all the food for…

>That is something that can be done at a local level without global cooperation.

You're assuming some foreign operator won't come to your local waters to illegally fish. China has shown they will fish literally anywhere they can get away with it.

China and Russia, are major over fishers. They have huge factory ships with swarms of smaller netters grabbing every fish they can. They do not respect size/species limits. Many countries have used armed patrol boats for offenders in their 200 mile economic zone. mid ocean sea mounts are have their fish exterminated by these vessels. Atlantic cod may not return because of over fishing on shallow banks that extend over 200 miles from Canada = where all fish are grabbed and the under 200 mile zone does not create enough young fish to compensate for these losses. Canada need to extend their control to the Grand Banks to add a contiguity zone. https://en.wikipedia.org/wiki/Grand_Banks_of_Newfoundland

As someone who eats almost exclusively vegan I think it would be great as the whole world faces these issues, we see lots of switches to eating tofu or plant based foods. Way cheaper. Can’t get so fat and unhealthy. And far healthier since most vegans and vegetarians live long and healthy lives compared to other groups. Poke tastes great with tofu btw. We shouldn’t destroy the oceans. Anyway I’m bracing for the inevi…

Japan, where tuna sashimi is popular (apparently they eat more tuna by far than any other country), has the lowest obesity rate of the OECD countries, and one of the highest life expectancies.

I have family working as a UN advisor on sustainable food chains and she says the entire ecosystem in the oceans could potentially collapse in 10 to 20 years if we don't stop large scale fishing entirely, especially trawl and unreported fishing destroying the seafloor and acidity going haywire. I have no idea if this is correct but i'm pretty sure around 1 billion rely on this food and can't imagine what would happen…

It's not could, but will.

The countries that are doing the overfishing have no intention of stopping. Western countries already heavily regulate their fishing industries.
