All I can say is infusing your atmosphere with salt will have an effect on the longevity of all metal structures, equipment and devices. I see it in vehicles from coastal areas and places where salt is used on the roads. All eaten up by corrosion in short order. That salt will gt scrubbed by precipitation, also, which means freshwater watersheds will increase in salinity, no matter how little, and that just can't be good for the biota there.
But unintended consequences are the hallmark of Leftist nonsense.
