| > which is an extremely wasteful way of producing food. Depends on what you are optimizing for. As a farmer, I can make more money growing crops for human consumption. It is the most logical business model. But the real world is a harsh mistress and the nature of... nature means that is isn't realistic to grow the same crops over and over and over again. Disease, soil health, etc. requires crop rotation to sustain a viable farm. Now the problem of equipment and markets. While I could theoretically introduce more human foods into the rotation, those human foods aren't compatible with the equipment I have. Nor is there a local market for them. This means more heavy iron, more trucking, more fuel, more fertilizer (no animals to help provide it), etc. Is that not a waste? I primary grow food for humans, but every 2-4 years (depending on the quality of the farmland) in my rotation a field will get a crop destined for animal consumption to address soil health and disease/pest control most particularly. If there is a way to avoid this without simply trading for waste somewhere else, I'm all ears. I'd be happy to grow nothing but human food. Agriculture is already excessively optimized to a fault, so it seems likely that we have already found what is least wasteful overall. Of course, if you want to minimize a specific waste to the detriment of others then no doubt the calculus changes. |
One of the things I've realized as I've gotten older is that parts of the economy I don't understand are rarely as wasteful as they might appear. Waste is super expensive and no one likes wasting money. The people growing alfalfa know exactly why they're doing it. It's pretty great we can regenerate the soil and feed some cattle at the same time, isn't that kind of sustainable thing the goal?
