I really do want to like the idea of vertical farms, and hydroponics in general as there are lots of benefits versus wild growing, but whenever I see some article claiming sustainability or a reduction in climate impact, it's total bullshit.

All of these systems require massive amounts of nutrients to keep the plants alive and producing, and that essentially means all kinds of mining. The byproducts of these facilities are also toxic, and there is no regulation about how they have to manage that...yet. Essentially they are just taking the farm runoff problem and moving it from rural areas where it's already bad, and transplanting it to denser urban areas.

If they could find better ways to streamline the acquisition of the fertilizer components needed for these facilities, and also the treatment or or disposal of the byproduct, these would be a much better idea.

I mean, an urban environment flushes tons of fertilizer down the drain every day...

Human waste is not suitable for fertilizer.

You should probably look up how most of your rice and beans are grown overseas.

See my other replies to this person.

It's not about the feasibility, but about the suitability.

I think a lot of people saw Matt Damon growing potatoes in human shit and thought it was legit and not specific to non-earth soil.
