I mean.. we really want to permanently desalinate the ocean somewhat too so putting the brine back seems kinda stupid. Put it on land, let it dry, sell some as table salt and dump the rest into abandoned mines.
Yea, that's one of the problems. We're literally digging up salt AND the mountains are being eroded to add more salt. The Earth is getting anti-terraformed and we're speeding it up. (Although obviously the fossil fuel situation is a much closer and worse problem)
