Earlier quoted context omitted.
WTF, most animals that are farmed are fed agricultural produce - crops that are cultivated. It's simple math that it's inefficient to grow crops -> feed the animals -> eat the animals. There's efficiency loss at every step. Are you seriously claiming that eating meat is better than being vegetarian?
Eating grazing animals is more humane per unit of protein than industrial crops or factory farming.
Not to mention the greenhouse gas effect of that many cows, which is much higher for grazing cattle.
