Saw a yt video recently that claimed the calorie efficiency of eating cows is about 3% (which sounds reasonable if you think about it). So then for every 100 calories we feed a cow, a human eats 3.
So even if you do use fertilizer to grow all of it… Growing 30 times less of it to fill the same need is a massive difference.
And then there’s the reduction of green house gasses that goes along with that too.
So unless fertiliser results in more than 30x yield, the cow is worse than eating the food directly.
Only thing is if its grass fed then its food humans can’t eat. But grain or soy fed cattle? We could eat that! And I can’t imagine many people are using fertiliser to grow grass. Well, except people into lawns.
