But then you doubt the number and not the general effect of reducing carbon emissions by switching to a plant-based diet, right? Because it is pretty obvious, that growing plants and then feeding those plants to animals is way more inefficient than eating the plants without extra steps.
a lot of what is fed to animals are parts of plants that people can’t or won’t eat. there may be some reduction but i don’t believe it can be anywhere near 70%
you can see that 17% of all soybeans becomes oil. but a soybean is only about 20% oil altogether. in order to extract that much oil, we must press about 85% of the global crop of soybeans. the vast majority if the soy fed to livestock is the industrial waste from that process. you can see in that chart it’s called “soy cake” or “soy meal”.
Well, if the first step happens (people going vegan), then other protein sources will be automatically in demand. A huge chunk of protein powder nowadays is whey, that can be easily substituted by soy, because of the sufficient amino acid profile of soy.

I’ve already told you that we can produce plant-based meat or soy protein for other uses from that, which you conceded, and you still call it “industrial waste”. Why are you knowingly spreading misinformation?
If the rest of the plant would be wasted, it would be more economical to just grow another plant that’s more efficient for oil production (canola, sunflower), not soybeans which are incidentally the crop highest in protein.

Do you have any sources on hand? It’s hard to google for this stuff without running into sites by PETA etc, which are too biased for my taste.
i don’t know of any broad surveys across crop categories but i’m pretty familiar with soy

elsewhere in this thread i mentioned cottonseed.
But then humans can also eat that soy meal to get their proteins. It’s pretty tasty, I eat it regularly.
people do eat soy meal but they eat very little of the amount produced. if the vast majority of it weren’t fed to livestock it would just be waste.
We are talking about a switch to a predominantly vegan diet. People need to get the protein they got from meat from somewhere else.
i think that’s a hard sell for most people and i frankly just don’t see it happening. do you have a plan to make that happen?

not only can we do that: we DO that. but there frankly isn’t enough human use for that, so it would be wasted if we didn’t feed it to animals.

It’s not grown in such quantities because it’s essential but simply because there’s demand for the extra protein from factory farms right now.
soybeans are grown for nutrient fixation in rotation with corn. they’re more of a soil crop than an oil crop.

“We need animal agriculture because we need to grow the feed plants to grow more feed plants for animal agriculture”
We’ve come full circle.

i am doing no such thing. i’m simply pointing out your lies.
