[ To produce just a single pound of meat, those animals may each eat upwards of 15 pounds of feed ]
This is stupid because animals that we use to produce meat are mostly all ruminants that are more efficient than we omnivores at breaking down down chain cellulose.
People cannot eat grass alone, they tried in N. Korea and they tend to starve to death...
It may very well take less resources to raise 15lds of low quality feed than it would to produce 5lbs of high quality vegetable human food.
However there are ways to COMBINE the two, in other words, you can raise carrots and feed the parts you cannot feed to human to a cow and eat carrots WITH steak.
I grew up on a farm and we raised corn, that corn can be used to make sugar and actual corn on the cob to eat. No we didn’t just throw the stocks away, we either ran the cows on them after the harvest or we baled them up after the combine collected the corn.
Also beef can be raised on ground that normally cannot be used to raise human consumption crops due to low water availability, hilly terrain, fields that are too small to deal with, ect.....
When you farm and have livestock it is a matter of “waste not, want not.”
But these dumb fools who pump out this anti-human propaganda don’t realize how the world ACTUALLY works...
And while pigs and chickens aren't ruminants, pigs can "follow" cattle and chickens can "follow" pigs and they all eat for free.
