> I think these figures are pretty misleading. First of all, they only look at calories, not protein. If you wanted to replace all the meat and dairy with equivalent protein substitutes you’d be looking at huge amounts of land for growing soybeans, peanuts, tree nuts. Replace all the milk with almond milk and you’re still dealing with huge water and land use for a product that has inferior protein and nutrients.
I don't follow — I get my protein mostly from grains and a small amount of legumes. In Australia, about 2/3rds of all crop production is grown as animal feed, and 90% of the food given to farmed chickens and pigs are grains [1].
> Second of all, you can raise livestock like cattle, sheep, and goats on extremely rough terrain. Good luck growing soybeans on a bunch of jagged cliffs. Those areas may be highly inefficient in terms of land area per gram of protein, but it’s not going to be productive farmland otherwise.
And you can grow crops inside vertical farms within urban areas.
