*What is lab-grown meat and how is it made?*
Instead of growing the entire animal, lab-grown meat allows you to only grow what you're going to eat, and that happens with cells. You grab some cells from the animal through a tissue biopsy, and then you can isolate and separate out the specific cells that you want. Then, you immerse those cells in a nutrient broth and that gives them all the nourishment that they need to grow and survive. And they’re housed in what’s called the bioreactor. The bioreactor controls all of the environmental conditions to facilitate and promote their growth. So as the cells grow in the bioreactor, they get to larger and larger numbers, and you can achieve almost an infinite number of cells from this process. Then, you separate the cells from the broth and form into a 3D shape that looks similar to a cut of meat, and that is what you eat on your plate.
*What’s the point of growing meat in a lab*
We have a meat problem. We raise BILLIONS of animals every year, and for many of them, the conditions are pretty terrible. AND the whole process is a big contributor to climate change in 3 big ways. Number 1 is land use and carbon dioxide.The earth’s surface is mostly water, and only a fraction of the land can be used to grow food. And most of THAT land is either grazing land for animals or land used to grow food to FEED the animals. We’re actually cutting down forests to make MORE space so we can eat MORE meat. And that’s a problem, because trees capture CO2, which you probably know is a BIG contributor to climate change. So, the more we eat meat, the fewer trees grow, and more CO2 escapes into the atmosphere.
Number 2 is fresh water. Raising animals for meat takes a LOT of fresh water - and that’s a finite resource. That means we can run out. Pound-for-pound, raising meat takes a lot more water to grow than a non-meat source of protein like soy.
Number 3 is greenhouse gasses coming from the animals themselves. They’re constantly emitting carbon dioxide and nitrous oxide, both of which contribute to climate change. Cattle are the WORST, because, well, cow burps! Each year, a single cow will belch about 220 pounds of methane, which doesn’t stay in the atmosphere as long as CO2, but is WAY WORSE when it comes to warming the atmosphere.

Would you eat lab-grown meat? Why or why not? Let us know in the comments below!
I would. ESPECIALLY if it was made to the same price or only slightly higher as the same amount of industrial farmed meat. I'd pick the one that is not having suffering as part of the way they are grown.
One thing you could make clearer is that vat meat is not a meat substitute. It's meat. It looks and tastes like chicken because it IS chicken. It's the same stuff a chicken's body produces via the laws of nature, it's just that the lab uses those same laws of nature to make the stuff without the rest of the chicken.
Yup. It is real meat!
It's not everything yet. I don't think they're making connective tissue or bone marrow. But they could.
Though not a big consideration for most people, my understanding is that lab-grown meat will not only be kosher, but also not count as "meat" for the purpose of the laws of kashrut (kosher food). Finally, we Jews will be able to enjoy cheeseburgers! 😆
You can do it now if you take a literal reading of the bible. Cows aren't goats, and it's batel beshishim that the milk comes from its own mother
@@KillerMZE Sure, but lab-grown meat will allow you to enjoy cheeseburgers even if you *don't* follow a literal reading! Hurray!
What about vegan cheese?
So... you're excited about the ability to partake in "sin" without the technicality? ....very weird
@@GoodnessGracious... I say this with love (and as one of them), Jews are the ultimate rules lawyers. It's the exact same mentality that lets my mother-in-law serve a table full of baked desserts at Passover, since they're all made with almond flour, potato starch, etc., even though they taste exactly like normal baked goods. It's part of the culture lol.
Super interesting! I would absolutely eat lab grown meat. I'm in a similar position where I love eating meat, but hate the animal cruelty in the industry. I actually tried to give up red meat recently and within like three months, I was anemic... sigh. It's tough. Lab grown meat could be an awesome alternative.
Thanks for watching!
I'm vegan and adopted a vegan lifestyle because of the cruel animal industry and negative effects on the planet (as pointed out in this video, thank you!). While I do miss some meat (pepperoni pizza!), I don't think I'll be jumping on the lab grown meat, as the smell and texture of meat grosses me out now. But I think this is great for getting folks to transition to a more sustainable and less resource draining diet! Plus, the surplus of soy and other plant based alternatives will hopefully bring about new "mock" meats (seitan is currently my favorite, and you can make it absolutely protein rich!).
I don't care if it's lab grown or not, all I care is if they can make lab grown bones too.
Joueur du Grenier fan?
At least the marrow
Yes, I'd love to eat lab grown meat. Very good analysis, guys!! You spoke about the energy needs which is something not many have touched on!
Thanks for watching! And the feedback.
220 lbs of meat per person, per year. That's 2-1/2 quarter pounders a day.
Just curious: Does that statistic take into account the population number of people who do not eat meat and extract that from the total population number?
Yup. It's the total U.S. meat consumption for the entire year, divided by the total U.S. population.
I can't imagine that these bioreactors would be less efficient than a bunch of animals who constantly need to walk around, digest things, and grow various non-meat things.
Although I am a bit concerned if lab meat would have the same nutrition as normal meat. I wouldn't want to buy a meat equivalent of a watermelon because the manufacturer wanted to save money on growth liquid.
it would be different even with care taken. needing to supplement the final product means its going to be difficult from the animal eating in the feed.
bioreactors are more efficient with input and output pure from feed to meat produced but more costly plus often the inefficiency is over estimated as more than meat are produced so it might actually be more efficient once all the useful products are factored in.
I'm excited to try it!
I would eat lab grown meat even if it was a little more expensive provided it tasted okay.
Artificial meat production will use orders of magnitude less land and water, which will be crucial resources as time goes on, especially since much of the cattle industry in the US is located in the Midwest and relies on groundwater resources for irrigation.
The real resource bottleneck is energy. Right now the energy costs are very high, but the outlook is good that those costs will decrease with time.
Combine the resource considerations with the more favourable ethics, and I think it's inevitable that lab grown meat will become the de facto source of consumer meat products in the developed world at some point in the future. But there will be a significant amount of resistance to overcome, even after the energy problem is resolved. Even now special interest groups are lobbying on behalf of the big cattle ranchers to stop artificial meat from being sold as "meat", or sold at all if they can help it.
Well said!
They can call pseudo meat. If it's nutritious, tastes good, and costs less, it will sell. I'd like to see a future where meat is either vat grown or grass pastured. Such purists would do better without the cafo farms anyway.
More good stuff. I am open, but unenthused, about it. Maybe the industry will change my mind. But like most things, at best it is a component. We shouldn’t lose site of farming as Expod describes in his comment. Larger scale but non-industrial farming is possible. It might not be a global solution to hunger, but neither is vat meat. We should welcome the innovations, but also look for lower tech, non industrial, sustainable solutions that are deployable around the world, not just shiny toys of tech companies.
8:50 Easy, Theres going to be thousands of livestock feedlots around the country not being used. build the tanks there, add a single wind turbine and some solar panels.
I don't know if it's that simple!
@@AboveTheNoise well they dont have much else to fix... already have water figured out, they're all already in the right spots to have access to rail infrastructure. So many people are going to be needing jobs when we cut back on meat, might as well bring the jobs to those people whom are losing them. instead of keeping this a silicon valley thing
Man, I'd love to try it! Probably will be expensive once it hit the stores tho...
Prices are coming down!
@@AboveTheNoise yes, that's true :) I also switched to vegetarian meat options since meat in austria is soo expensive haha
I don't eat beef, but you can pry chicken out of my cold dead hands 😅. Though I'm down for lab chicken
Personally, I'm interested in seeing if the practice itself could be replicated at home on some star trek food printer type stuff, Maybe with a sort of commercially available version of a bio-reactor made for in home use and the bio-media being sold in vials for personal or commercial use.
my Only real problem is the Nutritional broth itself, I kind of wonder if their are any other formula's for it that could be used as an option for the Bio-reactor and where one could get their hands on information .
Thanks for the video! Though I wish you had gone over two points you only barely mentioned: 1. Even assuming labmean always uses fetal bovine serum, how/how much death and suffering is it compared to traditional meat production? 2. Comparison on energy consumption and CO2 emissions from labmeat and traditional meat production?
We did bring up the issues of fetal bovine serum and energy consumption in the video.
@@AboveTheNoise yep. like I said, you just touched it, didn't show any numbers ;)
@@anakimluke We found it VERY hard to get specific numbers, 1 because a lot of this data is proprietary and companies don't hand it out and 2 it's hard to do an apples-to-apples comparison because there is no global, up-and-running lab-grown meat industry yet.
yeah im cool with lab meat. even if it costs a bit more.
Is it safe, is there any side affects later down the line and how can you tell the difference
6:38 Are those cows releasing a rap album soon?
Because, they look so. 😂
Lab-grown rap!
I'm hoping that the tech makes this protein source cheaper and more accessible to people who need it most.
I would definitely eat it but my concern right now is about the zero immune system of this meat (saw it on another video, don't know if is true though).
Could you please tell us what you felt was different when tasting it ?
Thanks for watching! As for your question about the immune system: that's why lab-grown meat has to have a sterile lab environment, kinda like in surgery, to prevent any bacteria or viruses.
As for the taste - the main difference was mostly texture, but chicken doesn't have a strong flavor, to begin with.
I absolutely would eat lab-grown meat-as long as it didn’t use FBS and wasn’t more environmentally harmful than regular animal meat. Lab meat may not taste exactly the same as the real thing, but that’s ok. I’ve barely consumed any cows milk in years (lactose intolerant) and at this point, almond milk tastes like regular milk to me because I’m used to it. They’re different, but serve the same purpose and taste good, so ultimately it’s fine. My hope is that as a society we’ll get to the same place with meat.
As a carnivore, I'm excited about this since I can get more food for cheaper and eat easier in the long run (hopefully, at least. I'm really hoping this type of meat will be infinitely cheaper).
I've been waiting for years for cultured meat to go to market.
For power, they could always use nuclear reactors lol
I feel like your chicken test was a little biased since you went there and watched him cook it and ate it, knowing exactly what it was. I feel like if you'd gone in blind, you would've said something different. Your brain is primed to know it's not real meat so your brain is going to make sure it doesn't taste like real meat.
Good point!
Very interesting video, but the fact that you still need to impregnate cows to make the nutrient soup potentially keeps animal suffering and cow burps in this loop :( I would like to see more on that or whether there are other alternatives.
Thanks for the informative video!
You know... it's like smoking. What is the "most safe and most healthy way to smoke"? Vapers, Tobacco, Pipes, ...
IT'S NO SMOKING. Eat less meat and the problem is solved. But yea, it's hard to go out of your way. I understand that it's hard to put the effort into changing your life.
Would I eat lab grown meat? 100%. In a heartbeat. No problem. Bring it on. We need it. Earth needs it.
This is so cool. 🐔
I can't wait to try lab-grown meat. I'm confident the obstacles around fetal blood (eesh) and heavy power needs can be surmounted, and while I am a dedicated carnivore, I agree that I'd really rather not have the guilt about something dying for my dinner if we can achieve that.
I'll bet lab-grown pork makes *amazing* sausage. Just sayin'.
1:37 After my own heart!
I would always buy cultivated meat over "traditional" meat so long as it is damaging the environment less.
Mad scientist meat vs. murder meat. Anyone in marketing hiring?
can you get some people to try a carnivore diet on lab grown meat only. i eat meat cause of the health benefits. not the taste. i tried plant based diet and had horrible depression and anxiety
My bet is still on genetically engineered plants that, when combined, provide all the key proteins needed to provide a very close match to meat flavor and texture, despite the bulk of the other protein being regular plant proteins. Growing meat cells still seems terribly inefficient by comparison.
That's what Impossible Foods does. They've been on the market for years now.
There is also "hybrid meat" that takes some meat cells and plant cells and combines them. Trying to get the best of both worlds, I guess!
I’d be interested to see you review Fossil Future by Alex Epstein
Why meat? I mean, humans can always create different food from different materials. In China we have many meat alternative foods made of soybeans etc for hundreds of years (Toufu is one of them), and it tastes nothing like meat, but still delicious in it's own way. Maybe the ultimate meat alternative is ... not meat?
Yeah I think it's just one more option for people that, hopefully, combined with other meat alternatives, will help out our planet a bit more!
lab meat is not looking like a viable substitue is most if not all areas. for nutrition it relys on supplements with out an herbivore digestive system. for taste and texture it relys on making and combining different cells and will taste different as how the same animal is fed effect tastes. unless major improvements that would get someone rich just from it happen it be too expenive for actual use and will be a noverty for rich people
Sophia is cute af!!!
Have you Eaten Lab Grown Meat in 2023? You May Be Entitled To Compensation!😂
For me, the whole "killing animals" angle is the least compelling argument for why we should be pursuing meat alternatives. Obviously we should have standards for the ethical treatment of livestock, but I have no moral qualms about killing another creature for food. People have to eat just as much as any other predator. We shouldn't feel guilty about eating the foods that we evolved to eat, even if that means other creatures have to die. It's the circle of life.
However, I absolutely agree that we need to take responsibility for our impact on the environment, and I see how our reliance on meat is an unnecessary contributor to climate change, and not sustainable into the distant future. There's a lot that we can and should do to minimize the negative impacts of the meat market, and synthetic meats like these might be a step in the right direction.
Will human now be on the menu um just asking for a cannibal friend
I have 10 chickens. I give them grains and bugs and they give me eggs and fertilizer in return. The fertilizer fills the soil with awesome nutrients. I can then grow delicious vegetables and give all the veggies scraps to my chickens, who will give me even more eggs in return.
ALL OF THAT did not require a giant factory that needs mining all kinds of metals and an overwhelming energy input to operate at base level. It just required nature.
I say nature is the solution for the damages our big industries have inflicted to nature. Another big industry is by far the stupidest solution to solve problems brought by big industries.
Nature, as it turns out, can be in really short supply. Considering population concentration in cities, a good percentage of people live in places without enough resources for raising chickens and growing vegetables. Other people do but have other issues, like contaminated groundwater (from fracking, GenX, etc.).
Raising your own chickens and growing your own vegetables is not a great solution. It’s nice that you can manage it but simply is not scalable.
Everyone having a small farm for all their needs from animals would definetly be optimal, but it's almost impossible to achieve in our current world. Already most people are living in tight cities in flats, and that number will inevitably increase with how rapidly our numbers grow. Even right now having some space for a farm is something very few can have. While there will definetly be problems, they will be far less dangerous compared to what will happen if we let the current meat industry continue to snowball its harmful effects to continue feeding the always multiplying amounts of mouths
That's not viable on a planet with 8 billion people, most of them in cities. If you replaced all the large-scale agriculture with small-scale agriculture, most people would starve. We don't have the systems we have now because we just woke up one day and decided it would be fun. They are solutions to real problems that unfortunately create different problems. Industrial agriculture has made food scarcity a thing of the past, but at the cost of environmental degradation and cruelty. We have to fix those problems but the challenge is doing so without bringing back food scarcity.
@@NoirKirbi You start from a false premise of "everyone needs to have a farm". That is a LIE. You need to travel a little and stop spreading lies.
@@fl260 Okay then what even was your point? You said "nature is the solution to all the damages our big industries have inflicted to nature". What are you implying we do here if not everyone having a little farm in a comment where you are in such detail describing how you have a little farm and praising it as a solution to all our problems? You are literally contradicting yourself, or are you implying we need to grow chickens and use their waste as fertilizers and feed them with scraps of vegetables but on a bigger scale to feed everyone? Sounds awfuly familiar to the agriculture industry causing all the problems right now doesn't it? Just so you know i'm not trying to twist your words for the sake of the argument, but i genuinely do not understand what message you are trying to convey
No no
So like bull to me
Booooooooo
