>How can science know when an ocean has become so salty that the marine ecosystem is endangered?
More to the point, you take water out of the ocean leaving the salt, if the water is not going back to the ocean, then ocean levels will FALL. Considering that the politically correct fear with climate change is that ocean levels will rise due to the melting of polar ice and glaciers, then desalinating the ocean to get fresh water would actually be a corrective action!
But of course all the water you take out goes back in. And the oceans get ever so slightly saltier every million years not due to anything puny humans can do, but due to the quazillions of gallons of water flowing in rivers back to the sea, picking up a tiny bit of salt and other minerals as they flow over the land. Eventually I suppose the oceans will be as salty as the Great Salt Lake, the Salton Sea, and the Dead Sea, but that might not happen until after the sun explodes.
Seriously, nothing humans are doing effects salinity of the oceans overall in any measurable way.
