I’m arguing with someone about using land to grow animals, or grow plants. Eventually he decided to pull out some hard figures:
Idk man, so if I had a 5x5 foot chicken coup I could house about a 10 chickens comfortably, that’s about 300x10 or 3000 eggs a year, in a 5x5 plot of land. That’s approximately 3000x70 or 210000 (!!!) calories. With lots of protein and other vitamins and minerals. (and you could fit even MORE chickens in if you were an inhumane asshole)
Now if you planted about 1 corn stalk per square foot, you’d get 5x5x1 about 25 corn stalks, and lets say you get lucky and get two harvests in, and even luckier and get 2 corn on the cob per stalk. So that’s 100 corn on the cob, or 100x100 or 10,000 calories.
Now, that’s a huge margin but of course you need to factor in the calories needed to feed the chicken, which is about 50 calories a day, (they can get away with less if you have land for them to peck at shit) or 500 calories per day for all 10 chickens, or 182500 calories per year. But then you have to factor in eating the chickens, which is about 5000 calories/chicken. Or 25,000 calories total.
25,000 + 210,000 - 182500 = 52500 calories/year for chicken
10,000 calories a year for corn.
Now, I’ve tried carrots, potatoes, and other foods, but somehow I can’t get the same amount of calories from the given land as the chickens. I know I’m doing something wrong, because he’s still losing potential energy, all that stuff going into bones, feathers, eyes, in the chickens moving around and making noise. Every time you go up the food chain, there’s always losses. Which also doesn’t make sense, because he’s getting more calories out than he’s putting in, even with all the energy expended to make chicken.
So anyone mind helping me out? I don’t mean drafting a response for me of course, but maybe point out what I’m missing, or what crop might be a better point-maker than corn?
