Scope Insensitivity

true.

I am from Australia though.

20 million total cows vs half a million in feedlots.

Brazil is one of the countries with the most cows

One “missing picture” in the Brazilian cattle industry though, is that of a North American-style feedlot. Only 4% of the cattle killed each year are “fattened” in feedlots. With Europe being Brazil's main beef export market, the majority is grown to finish under a hormone-free regime on grass pastures.

Scope Insensitivity

Yes 10 times as many plants need to be grown but the harvest methods are quite different.

A cow provides fertilizer(manure) and the farming equipment(it eats the grass there) .

I suspect based on my recollections sun->plants is 1% and plants->animals is 10% and animal->animal is also 10%.

Also per kg meat is more dense so you are shipping less of it.
