Straight out not the case. lots of animals are on farmable land. Also animals eat lots of our crops eg 80% of the worlds soy. Here’s one (of many possible ones) reference stating that we would only need 25% of the current agricultural land if the world went vegan. https://www.economist.com/graphic-detail/2022/01/28/if-everyone-were-vegan-only-a-quarter-of-current-farmland-would-be-needed
It absolutely could. Not with the current diet but if there was a shift to less meat then we could substantially reduce the amount of land used in food production.
vegan here who grew up on farms. Just because you don’t know them doesn’t mean they aren’t common.
So your data set shows 76% used for animals and 4% for industry. That’s very similar to the figures I referred to.
