Why is it akin to that? Doesn't the salt come from the sea in the first place?

replyMost of the carbon we spew into the atmosphere came from the air. Ancient plants took it in via respiration.
That still doesn't make it a good comparison. The salt emitted by desalination plants is already in the sea now, it's not salt that went somewhere else.
replyAnd the water we take out eventually goes back.
