You say that, but it’s not really just about grass-feeding. Cows are already fed almost 90% inedible crop materials that would be getting disposed of anyway. We could be doing better, but cattle’s food source is sorta the wrong focus.
And as much methane is in manure, it’s better for the environment (including GHG) than synthetic fertilizers.
The real answer is changing our meat/vegetable balance AND improve the process AND continue to improve humane regulations (and those 3 goals often synergize with each other).
The % that’s edible is not as relevant as the fact that it still takes much more human-edible feed
Not really. Definitely not if you consider the nutritional quality of the meat. And that’s beef, the worst example. (Feed to meat conversion from 6x to 25x, the higher number generally for free-range). Chickens are only x2 in ideal situations (closer to 5x when free-range since their calorie intake is not as well-managed). And from a health viewpoint, 100kcal of chicken is a better-balanced calorie than 200kcal of feed
But that is before accounting for the fact that about 165 of those feed kcals are inedible, meaning you’re trading around 35 edible kcals of corn for 100 edible kcals of chicken. Would you agree from a purely health and efficiency point of view (leaving out ethics), that 35 edible calories of a “non-nutritional grain” for 100 edible calories of a protein superfood is a pretty fair trade?

Synthetic fertilizer usage is greatly reduced by eating plants directly even compared to the best-case use of animal manure
