Other arable land is used for animal feed production, and together with grazing land represents the other 77% of agriculture land (37 mil. km2), which supplies 18% of global calories and 37% of proteins.
Those 23% (11 mil. km2) of agriculture land, crop land, is capable of producing 82% of global calories and 63% of proteins.

Right, and since we're only talking about cropland, that 77% has no relevance to the discussion. That it keeps coming up is rather bizarre. Indeed, if you keep pounding a square peg into a round hold hard enough it may eventually go in, but one sure does look silly for doing it in the first place.

"Arable land is classified as land that can be plowed for the purpose of growing crops."
Please, look at the graph one more time.
Wrong.
> ~60% of the soybeans are intended for direct human consumption and ~40% for animal consumption. I imagine that is not atypical

Wrong.

Wrong.
> Arable land includes meadows, pastures, etc. Animals can (and do) eat from those lands, but cropland is more specific

It's called logic. I give up.

Even if we kept all the arable land for human consumption (to compensate for missing meat, assuming the lab-grown meat will take some time to scale) we'd have 3.3 billion hectares of pastures to rewild/reforest. Or we could reforest those 35% of arable land we use for growing animal feed and instead use a fraction of pastures for nuts/fruit production.

Forests cover 40 mil. km2, and animal agriculture takes 37 mil. km2. Majority of plant-based foods is produced on 11 mil. km2. By switching to plant-based we could increase forest cover from 40 mil. km2 to 70+ mil. km2.
"We might even address the very real disaster scenarios presently threatening the world with questions like these: "What if you could make a simple and compassionate change in your life that would increase available farmland, increase available clean water, reduce rainforest destruction, reduce greenhouse gas production, reduce the threat from antibiotic-resistant bacteria, decrease land and waterway pollution, prevent creation of ocean dead zones, end your participation in the deaths of sentient individuals and increase overall human health by switching to a plant-based diet? Would you do it?” This is the reality we actually live in, and this is the choice each one of us faces."

OFF-TOPIC: we should reforest some deserts/barren areas as well
