Is my math correct? A question about the impacts of vegan and omnivorous diets.

Question

I am writing a speech about veganism, and I found a statistic saying that to feed a single vegan in a year, it would only require 1/6 of an acre of land, and for a typical American omnivore, it would require 3.25 acres. One acre is 0.00404686 sq km, and I m using a world population value of 7,365,455,150 people. Also, there are 16,163,000 sq km of arable land on the Earth. So, am I correct in saying that if everyone on the Earth were vegan, it would only require 4,967,830 sq km of land (~31% of the world s arable land), and if everyone on the Earth ate like a typical American omnivore, it would require 96,872,700 sq km of land (~599% of the world's arable land)?

Thanks!

Yes you are right.

As for your calculations and assumptions, they appear to be correct so far. Generally speaking, a vegan requires one unit of land to have food, a carnivore requires ten, and an omnivore requires somewhere in between (depending on their diet). Indeed, the world population is approaching 7.4 billion and still growing (census.gov). There have been some advances in agriculture, like growing fish and rice simultaneously, and the number and size of greenhouses have increased. An additional fact is that wild fish populations have reached their maximum size. You are right, of course.
