By desalinating water on any large scale, one necessarily increases the salinity of the remaining water left behind. This causes a disruption in the halene isobars, and changes the ambient temperature of the local oceanic body of water, thus displacing native species of fish, and even eliminating the habitat of various flora and fauna. Hence, mass desalization of ocean water both threatens wildlife, and causes global warming on a local scale.

(all of which is true - but, it is also insignificant).

Only if you return the separated salt to the body of water instead of, say, purifying it and selling it on the grocery store spice aisle.

Oh come on, the chance of ever de-sal’ing enough water to cause any change in the oceans is pretty far fetched, wouldn’t you say?

"By desalinating water on any large scale, one necessarily increases the salinity of the remaining water left behind."

Assuming that the salt from the filtered water would be dumped back into the ocean? ;-)

[enduserindy]

That assumes the salt removed is returned to the ocean.

If you extract the salt and you do not drop it back into the ocean, the seawater would remain constant. Of course you would have mountains of salt laying about.

[Boogieman]

Well, you could just answer that theoretical lib argument by promising to dump all the town’s wastewater back into the ocean to complete the water cycle. Oops, they wouldn’t like that either, would they?
