The only skepticism I have here is about salt. If salt is continually moved from salt mines and put into our food, it will come out of our bladders and into the ground. Then salt could build up near the surface over time. Salt is an impossible problem to overcome for growing some crops and flowers. I don't know what the time frame would be for this to happen. Perhaps it's time to stop using salt in foods anyhow.
