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.

Pescatarian diets are as healthy or more healthy than vegetarian or vegan ones, and much easier to adhere to in terms of getting the required proteins and amino acids.

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 Japan could do something about it though. If they stopped over-fishing, that would just attract Chinese fishermen who would fill the gaps. Just can't win without global cooperation.

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 the large breeding populations necessary for 
  preservation of the species and widespread deforestation, which destroyed its habitat.
  A slow decline between about 1800 and 1870 was followed by a rapid decline between 1870
  and 1890. In 1900, the last confirmed wild bird was shot in southern Ohio.

So too shall go the tuna. The size of a single tuna is already 50% to 70% smaller than normal. Soon their populations will go into freefall once there's not enough mature ones to spawn. The fishing will continue until there's no more. Even if legal limits are imposed, fishing will just continue illegally as it already does today.

Nah you can eat just as bad vegan food. Most vegan burgers are just fat patties much worse than those made of lean beef.

As with any type of food it depends on the choices you make within the class and the amount of it.

I think the reason vegans and vegetarians are healthier is mainly because they are more conscious of what they're eating in the first place.

And depending on where you are it can take a lot of effort so it rules out "comfort food" people. I'm not sure about the US but here in Spain it's actually quite difficult to be vegetarian, there's not many local restaurants that serve veg options. More so when it comes to touristy places but still.. In Holland in comparison the supermarkets and restaurants are full of them.

> We shouldn’t destroy the oceans.

Totally agreed here.

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 a single fish when they're still in easy supply.

I had assumed that this article would be talking about bluefin, was slightly surprised. It's kind of screwed up, if you ask me.

Not a fan of sushi, and I guess I didn't know what a poke ball, but it's not just the fish favored by Japanese cuisine. I don't even know when the last time I would've eaten real cod at Long John's... in the 1980's as a kid? Now it's all something like Alaskan pollock or whatever. Gulf coast shrimp, shellfish off the east coast, very little of it seems to be in good status.

We'll probably just figure out a way to switch to farming these fish or something very similar to them once we finish destroying the wild ones in the ocean.

I second this 100%.

Society overall is in a level of denial towards the very negative impact of cattle farming on the planet like it was in the 50s towards tobacco.

People will bitch about a cigarette being smoked 10 meters from them, but will shove sausages and stakes down their throats every other day pretending it doesn't have a gigantic cost in terms of earth's resources or the many studies pointing about how unhealthy it is.

Mind you, I don't advocate for people to cut off meat entirely, I myself have no intention to do so, but if we globally halved this crazy meat culture the impact on the planet would be huge.

We eat unhealthy and we're killing the planet while pretending to be green with Tesla SUVs. We're doomed to keep making this planet worse.

> 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.

There are over a billion people that don't eat meat by choice on the planet and another billion plus that have low access to animal protein.

We can attempt to fix it before ecosystems collapse, if we do it afterwards, the only meat you will be eating will be worms.

This is an extensive review of many papers from 10 years ago, most data agrees that vegetarian diet is considerably healthier.

More modern literature merely adds that if you go full vegan you need to eat quite some if you want to preserve lean mass.

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…

They have already collapsed some places in the world. Like the Baltic sea where a keystone specie like the cod is in so much trouble that it seems irreversible.
