People living on plants

"I was in Munich. I went down to the vegetarian restaurant at noon. I look at the menu: lots of different dishes. Most with sour cream. Plenty of butter and cottage cheese. Egg dishes, too. One guest drank milk instead of wine. The place got busy. A friendly German came to my table. We chatted. I ask him if they don't eat meat because the food is healthier that way? Or because they feel that killing an animal is a beastly act? He replies: - For both reasons. - So now tell me: is it possible that at some point all people will convert to a vegetarian lifestyle? - We hope so. - But what do they do with all the roosters that hatch from eggs. - Nothing. Let them live and crow. - I see you're not a farmer, so you can let them. But poultry need forage seeds, even in summer. Forage seeds cost money. And then the roosters themselves kill each other: only one remains in the yard. - Well, that settles it, laughs the German. - Good. But look: you also eat milk. The cow doesn't give milk until after calving. And every cow often have bull calves. Where does the world put all those bulls? Because in just a few years there would be so many bulls in the world... - They also kill each other. - No, they don't. They just knock each other aside. Go to another frontier! And in time they'll graze the grasslans, the fields, the wheat fields, the barley fields, the beet fields, the corn fields... And more and more and more. The German could not answer. Maybe other vegetarians can."
