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.
