Reply to comment by [deleted] in Does the salinity of ocean water increase as depth increases? by rhinotomus

With countries like Israel being at the forefront of desalination for drinking water, if more countries use desalination will that have any effect on oceanic salinity? Or is it too small to have any impact at all?

There can be an environmental hazard when waste salt is dumped resulting in toxic levels of salinity locally but overall increase in ocean salinity is negligible.

On the flipside, desalination might very well pay for itself in the future when paired with operations like the harvesting of lithium, hydrogen and chlorine from ocean water. https://www.intelligentliving.co/desalination-device-harvests-lithium-h2-from-seawater/amp/
