Vertical farming, the best solution to support an ever growing population or just a scam?
IMHO it has a lot of potential but not being able to grow grains really is something that should be tackled sooner rather than later. But I could see this being used by self sustaining communities to provide lots of food while using very little space. And it’s technically more environmentally friendly than just using vast stretches of land to produce the same amount of food.
Depending on how you generate power, you could use LED grow lights in vertical farms. You also have the luxury of working in an environment that you can tightly control; that means you may not need to use pesticides or herbicide at all. If you aren’t working in large fields, you can get away from using heavy diesel farm equipment.
Fundamentally, we need to use less land for farming, we need to use far fewer pesticides and herbicides, and need to reduce the emissions associated with farming. Vertical farming has the potential to help with all of those.
The pest control is true for the short term, though I find that over time even well kept facilities develop some kind of pest problem.
maybe if they kept chickens in the lobby…
You could, for instance, shut down at the end of a cycle and do a thorough cleaning without using pesticides. Using steam, heat, and high-powered ultraviolet light, you should be able to effectively kill any pests or eggs that pests are leaving. Yes, pesticides are certainly less expensive in the short run, but in terms of long-term health for the entire planet, they’re super-bad.
