Be nice. Assume others have good intent (within reason).

Use content warnings and/or mark as NSFW when appropriate. Most posts with content warnings likely need to be marked NSFW.
Most 196 posts are memes, shitposts, cute images, or even just recent things that happened, etc. There is no real theme, but try to avoid posts that are very inflammatory, offensive, very low quality, or very "off topic".
Bigotry is not allowed, this includes (but is not limited to): Homophobia, Transphobia, Racism, Sexism, Abelism, Classism, or discrimination based on things like Ethnicity, Nationality, Language, or Religion.
Avoid shilling for corporations, posting advertisements, or promoting exploitation of workers.

Moderator Guidelines
Moderator Guidelines
- Don’t be mean to users. Be gentle or neutral.
- Most moderator actions which have a modlog message should include your username.
- When in doubt about whether or not a user is problematic, send them a DM.
- Don’t waste time debating/arguing with problematic users.
- Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
- Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
- Ask the other mods for advice when things get complicated.
- Share everything you do in the mod matrix, both so several mods aren't unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
- Don't rush mod actions. If a case doesn't need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
- Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
- Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
- Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
- First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
- Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
- No large decisions or actions without community input (polls or meta posts f.ex.).
- Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
- Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.

No more farmers, lab grown food! Better for the environment, better for animals. Win win. Farmers in The Netherlands are seriously fucked up, going as far as threatening politicians with murder at their private home. So fuck meat, dairy and egg farmers. We only need fruits and vegetables, and lab grown meat is a nice addition.
I didn't find an answer in my very limited search for what is actually used to grow the meat, so depending on what makes up the "stuff" that brings nutrients into the growing part, we may still need a lot of farmers for something like this. There's also no way the growing environment, which seeks to create an artificial "animal", is energyefficient.
I'll celebrate the day we don't need farmers, and I'll celebrate the day it'll be at least environmentally equivolent, but until I see evidence of those things, I'll be very sceptical of this stuff.
Why not, could you elaborate on this?
My thought process is that if you have to mimic a living environment, you still need to include most of what the natural environment needs. The one artificial meat I've read about had the meat growing in vats of some "solution" that mimics the natural environment of the meat (so like a body). Granted, the process in the post may not function like this, but if it does, that process would include:
These are all just speculations, please feel free to prove me wrong on any of them, and be sceptical of my list. But this is what I'm sceptical about with the very lacking information in the post.
The biggest challenge is the bio-reactors, they are hard to scale and require more delicate care than other cultured products because growing muscle, fat and tissue cells is a lot slower than say, getting yeast to reproduce. This a challenge but not a deal-breaker, there are some places already selling cultured meat but it's still expensive (like, $40 for a burger) because of the scaling problems, which again, come from lack of funding and political pressure.
That said, most other challenges are either overcome or there are companies with solid methodology but no investment capital, and since many places are actually banning or outlawing the sale of cultured meat, we likely won't see much actual progress until we get corporations out of politics, so maybe never.
Cows right now isn't even grass, they're fed mostly grown crops. The trophic energy loss at each stage is generically 10% , so plants to cow to human you lose 90% of the energy each time. So for eating meat you only get 1% of that energy from the sun. If you ate wolves who ate cows it would be .1%.
For energy this will, once it's at scale, be able to be more energy efficient pretty easily. Because for one cow you have to have the entire life of the parent animal then wait 2 years for the animal to grow up. It has to eat and move around and waste energy that entire time. Less than half of that animal has the desired final product, so you waste more there. So the idea is that with growing this you just start with some cells and then increase their size until you get enough and then package that.
