"we have to give it up"

"Nothing is as destructive to people, animals and the entire planet as factory farming," he says, as he rattles off one number after the next. He is even familiar with German figures: "Twenty-one thousand animals die to feed an average American. Ninety-nine percent of those animals are mass-produced. In Germany, the number is 98." Then he shrugs his shoulders and says, quietly, almost matter-of-factly: "There's no good way to feed 6 billion people with 50 billion animals. So we have to give it up."
