Ignore the alarmist aspect of the above article. The content is true.
People like Gates, Ford Foundation, Rockefeller Foundation, Cargill, Bayer(who bought Monsanto) are pouring millions into Vertical Farming. Walmart, Kroger, Amazon Fresh and others already sell salad greens grown in vertical farms. The plants never see sun (LED), some don't grow in soil(aeroponics), they're gene-edited plants using CRISPR Cas9 and of course they're patented.
Livestock is also being gene-edited and most likely will also be patented.
Lots of major corporations getting in on this.
They're working on gene-edited tomatoes to grow in vertical farms to fit the same systems that salad greens grow in. Why adjust the equipment when you can adjust the plant?
Concerning aspects:
Everything proprietary and patented is the big one. Want to grow grain type corn? It's Monsanto's patented seed or nothing. They want that for all food.
Plants grown under LED lights and without soil in a sterile environment. What's the long term effect? What about our gut flora?
I would imagine some gene-edited food plants will be grown in the field. What happens when they cross with other varieties? Does the patent holder sue the farmer like Monsanto did?
All of these vertical farms are in urban areas of course. That will be handy when they force people into the cities. We'll have salads, lab grown meat and bug protein to eat. We'll own nothing and be happy.
All the same people are working on digital ID systems and pretty much every country is researching or trialing Central Bank Digital Currency. Welcome to slave planet.
