No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)

Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.

Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.

Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.

Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.

Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.

Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

Rule 10- Majority of bots aren't allowed to participate here.

[Answered] Why is the consumption of Meat considered bad (lemmy.world)

I heard something to do with Nitrogen and …cow farts(?) I am really unsure of this and would like to learn more.

Answer -

4 Parts

  • Ethical reason for consuming animals
  • Methane produced by cows are a harmful greenhouse gas which is contributing to our current climate crisis
  • Health Reasons - there is convincing evidence that processed meats cause cancer
  • it takes a lot more calories of plant food to produce the calories we would consume from the meat.

Details about the answers are in the comments

I have seen your math but your math doesn't make any sense since you are doing your math on the wrong assumptions. You assume that the ourworldindata chart shows that at the end 17% of the weight of the global soy productions ends up as oil but that's not what this chart is showing.

What it's actually showing is that for example if we produced 100kg of soy globally 13.2kg of of that produced soy is used to make oil. Which means that the actual weight of the oil is 2.64kg in this example (assuming it is correct that soybeans are 20% oil, and we extract it perfectly)

the ourworldindata chart has another 4% of oil at the bottom.

Are you talking about the Industry percentage? That's not oil. But even so your math is still wrong as I've demonstrated in my example above.

  • approximate percent of soybean that is oil = 20.00
  • percent of soy fed directly to animals = 7.00
  • percent of soy fed to dairy = 1.4
  • percent of soy fed to beef = 0.5
  • percent of soy fed to pets = 0.5
  • percent of soy fed to aquaculture = 5.6
  • percent of soy fed to pig = 20.2
  • percent of soy fed to poultry = 37.0
  • percent of soy that becomes human food = 20.00
  • percent of soy that becomes oil for food = 13.2
  • percent of soy that becomes soy milk = 2.1
  • percent of soy that becomes tofu = 2.6
  • percent of soy that becomes tempeh etc = 2.2
  • percent of soy that is fed to animals = 76.0
  • percent of soy that is used industrially = 4.00
  • percent of soy that becomes biodiesel = 2.8
  • percent of soy that becomes lubricants = .03
  • percent of soy that has other industrial uses = .07
  • percent of soy not fed directly to animals = 93.00
  • if all soy not fed directly to livestock were pressed for oil = (approximate percent of soybean that is oil / 100) * percent of soy not fed directly to animals
  • soy eaten not as oil = percent of soy that becomes soy milk + percent of soy that becomes tofu + percent of soy that becomes tempeh etc
  • if all soy not eaten directly by livestock and not as non-oil food is pressed for oil = (percent of soy not fed directly to animals - soy eaten not as oil) * approximate percent of soybean that is oil / 100

If we take 7% of all soy out because it's fed directly to animals, and another 6.9% is eaten, but not as oil, and 20% of each of the remaining beans are made of oil, we find 17.22% is the maximum amount of oil we could get if all the soy beans not fed to animals or eaten by people are pressed for oil.

It turns out that the chart shows 13.2% is oil for humans to eat, and 4.0% is used industrially (and these are all oil uses), totaling 17.2%,then basically all soy not eaten directly by animals or as various human foods is pressed for oil.

what kind of lubricant can you get out of a soybean that isn't soybean oil? you don't seem to want to believe the truth when it's been explained as clearly as its possible.
