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.
That is a very interesting perspective, thank you for making me think of things in a slightly different light. But yes I agree any type of advancement in farming from this point in human history and onwards should be attempting to achieve 2 things:
Dont poison the planet (we kind of need it)
Make food preferably with some variety
