Browsing social media, it’s apparent that people are quick to point out problems in the world, but what I see less often are suggestions for how to solve them. At best, I see vague ideas that might solve one issue but introduce new ones, which are rarely addressed.
Simply stopping the bad behaviour rarely is a solution in itself. The world is not that simple. Take something like drug addiction. Telling someone to just stop taking drugs is not a solution.
And vertical farms.
My understanding is that vertical farms have yet to prove more efficient except perhaps in land use. It’s been pretty hard to scale.
