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.

95% water. The economics just don't work. Is spending dollars in fuel to move tons of water from the sea, trow the 90% again to the sea and sell the remains for pennies.

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…

> Can’t get so fat and unhealthy.

It's super easy to be vegetarian/vegan and eat mostly junk food.

American supermarkets are filled to the brim with potato & corn chips fried in vegetable oil and sugar drinks of all kinds.

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.

it doesn't taste like anything... it's 90%+ water, and water solid remains is basically tofu: absorbs the flavor of what it's cooked with

And this plan will be a failure from the start. The pool of edible species is just a very small part of the total.

Leatherback turtles eat jellyfishes. What if we stop killing them instead? or increase the ludicrous amount of resources allocated to protect turtle nests?

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.

I've always heard predatory species like tuna cannot be farmed, but my knowledge may be outdated

Maybe. Cod suddenly collapsed by like 98% but never went extinct.

Probably a dumb question but why hasn't cod rebound on the east coast? The fishing moratorium has been in place for decades now, shouldn't the population have increased exponentially since then?

> 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. 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.

That's not because they eat tuna sashimi, it's because they eat relatively less processed animal products.

> We shouldn’t destroy the oceans. That's why this isn't great. Because this is not "we went vegan to save the oceans". It is "the oceans look like they are already destroyed". Besides that, I haven't seen any studies that show a vegan or vegetarian diet makes someone healthier.

> Besides that, I haven't seen any studies that show a vegan or vegetarian diet makes someone healthier.

You must not have looked. Almost all (except for commercially funded) studies prove plant-based diets are much healthier; it's literally the scientific consensus in nutrition.

You're right, it's the way forward, but I don't think you're helping by making it seem like the easy path. You have to pay more attention to your nutrition if you want to stay healthy as a vegan, and attention is under attack these days.

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.

The EU's Common Agricultural Policy.
