Every form of production will have defects. The goal of perfecting production is one to be sought, but never achieved. We should always try to make food production more efficient with less loss, but there will always be loss, and always be waste.
Even new means of production like lab grown beef can have waste and loss in batches that don’t “grow” properly because they didn’t mix hormones correctly or whatever. I actually don’t know how the science behind that works, but I do know it’s a process. And where there’s a process there’s room for error. That’s where we get loss from.
We’ll never make something fool proof. Perhaps lab grown meats will be the most efficient form of product in that they have the lowest loss and production can be tweaked fairly quickly so there’s not a lot of loss and ramped up for shipments to areas with food shortages. Honestly, lab grown in my opinion has the best chances of being a major breakthrough but it’s still too early to be sure.
