I was trying to show that the world doesn't give a shit about your efficiency. You can get all the proteins you need from a vegan diet.
If you want to eat 1800 calories of peanut butter to get the same protein as a burger patty be my guest, when you're 500 pounds, you might realise that isn't the way to do things.
If you are willing to sacrifice up to 97% of the nutritional energy going into production of your meat, if you are willing to accept ridiculous amounts of greenhouse emissions, that makes you quite egoistic in my eyes.
It's not "nutritional energy" it's energy, i.e. calories. Also, that statement is mixing a bunch of different things together ultimately producing something so far removed from reality, it's not even worth mentioning.
All farming accounts for 7% of the GHG emmited, which is about the same as all cars on the road. Feeding 7.5b people costs the environment the same as the entire personal transport industry. Not a bad deal at all if you ask me.
So best case scenario is 4/5 going down the drain? Bra-vo. Nothing to add there.
No, as I stated, best case is 20%. Don't forget, all livestock is eating 1/3rd the grain and cereal, and grass, which is where this efficiency figure is coming from. We eat grains and cereals. It seems fair that we produce enough to feed animals that convert it into more important nutrients for the human diet, than trying to live off grains.
Because of legumes containing a lot more protein? I suppose, they mean mostly soy.
Because soy is horrible for the enviroment, and I didn't think anyone would be stupid enough to argue against GHG and then argue in favour of soy, but you're the second person to do so now, so tickle me pink because I'm a bit shocked to be honest.
Also, your statement that a steak covers half your daily income and your conclusion that "having a steak once or twice a week is a pretty good way" leaves me confused. Not checking your numbers there, but if a steak corresponds to half the daily intake, that steak per week only covers 7% of your weekly intake. Where do the 93% come from?
The other meals people have, with other meat products? Thought that was pretty obvious. Most people don't want to eat steak every day, they have a varied diet, with ham, chicken, turkey, beans as you've mentioned, veg, etc.
If it's possible to get 93% from plants, why would you have to weigh 400 punds to push that up to 100%?
It's not... I'm genuinely shocked you're jumping to these conclusions based on what I said, it's like you don't know how humn beings eat or something. Ye know, 3 meals a day, 7 days a week, usually with a good bit of variety and snacking? wtf man.
You mean B12 that is grown in labs and added to the diets of animals?
Only if the animals are unhealthy, and this is not common practice, and definitely is not common practice is grass fed livestock, which live happier healthier lives. If a farm has to give their livestock b12, there are greater issues at hand.
You can just take the cyanocobalamin supplements yourself instead of relying on cows take them.
Or I can eat the grass fed beef and chicken I've been enjoying my life so far.
as you can easily cover your protein demand with a plant-based diet
"easily" hmm, as we've said, soy beans are the best protein rich food for vegetarians, and it is also horrible for the environment, and I believe I've read it's bad for the digestive system similar to corn as well.
Including that middle man "cow" still wastes most of the protein and energy you feed, even if you claim it's nonsense - Your numbers don't add up
I mean, if you consider feeding animals "waste" sure, these are living creatures, and they need to be fed. The alternative is to let tens of millions of them die, and work endlessly to try and replace the value they provide to human society with vegetables, which would likely be just as wasteful and ecologically disaterous as simply feeding livestock. Have you ever stopped to think about the variety of vegetables would be required to replace meat from the human diet? The land mass it would take up? The damage growing certain foods and pesticides would do to the eco system and soil? Trillions of insects would be killed at the very least.
Your numbers don't add up
considering how you've struggled to read them that makes sense to me.
