I'm talking about while you are growing the meat, whether it be in a natural system that is self-regulating and with an immune system, or in a vat where any contamination will spread rampantly. That's one of the biggest problems with lab-grown meat: if you make it at a scale that is economically feasible, the chance for contamination is so high that very few batches will make it through the process, and will have to…

We do large batch cheeses and beers and other things like that; which are similar enough that they'll offer useful pointers. "Meat" cultures might well be more subject to contamination because of the conditions required, but still. It's not a new problems and there's solutions that have worked for similar cases. I do not think they will be able to compete economically with the backyard chicken, for example; but I'm n…

I'm not an expert but it might be that the cultures we have chosen for beer and cheese and so on are those that outcompete most others while still not being harmful in by-products to us. This might take a while for lab grown meat.

If you work out how to eat straw and bean stalks, and tough heathery grasses, then you've got a real moneyspinner on your hands.

>eat This is exactly what I mean - the statistic has convinced you of some unwritten law that says that only livestock or humans can eat this stuff. Since humans can't, it has to go to livestock. But you're completely ignoring that processing these inedibles doesn't have to come in the form of eating them - we can make compost, building materials, packaging. Just because something is doesn't mean it ought to .

You can't really make packaging materials from tough cellulose-y things like bean stalks because mice eat it, you can't really make building materials from it because it goes on fire, and because it's tough and made of cellulose it doesn't really break down well in a compost heap.

Do you know what composts that stuff like crazy, though?

Feeding it to cows.

And even better, it reduces methane and carbon dioxide emissions, because you're turning all that carbon into cows instead of just letting bacteria emit it as gas.

I eat meat, but I think it's fair to say bringing living/feeling/thinking things into existence for the express purpose of being killed and consumed is grim. This feels particularly true if the circumstances they're raised in are horrific, which seems to be pretty common in factory farms. In any case, nature might be crueler to living things than we are, but I still think becoming less cruel is worth the effort.

Wouldn't the logical conclusion than be to eat less and higher quality meat? I mean I have worked on Biodynamic farms with lives…

>when most Asian diets are mainly vegetarian and have fed populations in the billions for millennia (eg India, China, Japan).

The modern Japanese diet is very, very far from vegetarian. In fact, you'll have a very hard time eating in restaurants if you're a vegetarian in Japan. I guess if you consider fish to somehow be "not an animal", though, it's much easier.

I'm no vegetarian by any means, but equating the life of corn to the life of a relatively intelligent animal like a pig is really, really disingenuous

But why is it disingenuous? Both are masses of living cells. Both die after damage or neglect. I'm just highlighting our species' biases. My cat for example is intelligent but has no such biases, eating rodents, insects, and catgrass with the same violent gusto. I'm just pointing out its a bit of a human fallacy to label some organisms as off limits and others for our harvesting, when no other forms of life do this.…

> It just seems like a solution looking for a problem to me. Vegans primary objection to eating meat is that it is murder. Meat eaters primary issue with vegan cuisine is that it does not include meat. Hope this helps!

> Meat eaters primary issue with vegan cuisine is that it does not include meat. In my extended group of acquaintances, the distaste for typical vegan food isn't that it doesn't have meat, it's that it tries to pretend that it does and ends up being kinda gross as a result.

Those meats (btw, not a typical vegan food) are trying to be as close as possible to the real thing to help convert meat-eaters into vegans.

And they're doing good job - I know of some long term vegetarians/vegans who don't like some plant based meats not because it's gross, but because it's too similar to the real thing.

When you switch to plant-based, in time your tastes will change, and you'll no longer miss meat/cheese ... however unlikely it may seem to you now. Maybe because cheese & meat are addictive.

Bugs carry parasites. Lots and lots of parasites. And parasite eggs. Cultures that eat insects also have high rates of parasitic infections.

FYI I wasn't posting about how good bugs are, I was posting about the negative impression that vat-raised meat can have, which is a bit like the negative impression about bugs. Your own post is a bit of an example of reactionary posts about foods that somehow "disgust" others with opinion sometimes disguised as research showing all kinds of "problems".

I was implying that there's a reason why people have a revulsion to eating bugs. It's rational. It's not just "cultural squeamishness". I should have explicitly stated my intent.

> Half of the world’s habitable land is used for agriculture ... While true, we are talking about cropland , not agriculture land (e.g. pastures). Nowhere near 50% of the world's land area is suitable for cropland.

Yes, it is ... simply deforest more land for our animals ... we could fatten ourselves so much more ;) https://ourworldindata.org/land-use

Your own link suggests that only 23% of agricultural lands are suitable for cropland.

Not being exposed to air, for one. That's why it's safe to eat a rare steak (where the surfaces exposed to air are cooked to kill bacteria) and why it's not safe to eat rare hamburger (where all the meat has been exposed to air through grinding the meat).

> That's why it's safe to eat a rare steak The USA department of agriculture begs to differ. https://ask.usda.gov/s/article/Is-a-rare-steak-safe-to-eat Personally I never place much trust in random comments on the internet.

It's more like the USDA is begged to differ.

They exist to be an ultimate authority, and that constrains them from presenting a compromised position, even if that compromise is something people find widely acceptable. The USDA simply isn't in a position to guarantee enough safety in this case to balance against their liability.

Safety is compromise. Eating rare steak is risky, but most of the risk is mitigated. Getting sick from eating rare steak is, itself, rare.

>And even better, it reduces methane and carbon dioxide emissions, because you're turning all that carbon into cows instead of just letting bacteria emit it as gas.

Cows don't work as carbon sinks if you're killing them every 2 years to eat them. You're just reintroducing that carbon in the form of sewage, transportation, and food waste. They need to be allowed to live all 20 years of their lives for the carbon efficiency argument to work. This necessitates (1) massively reducing the population of livestock by ceasing breeding (otherwise it's hurting any gains with carbon storage in the soil) and (2) finding alternative uses for the inedible byproducts of plant agriculture.
