You do realize that once water is removed from the ocean, it goes through whatever use it is intended for (irrigation, human consumption, whatever), where it then goes back into the water ecosystem and ultimately returns to the ocean, right?
Imagine this- you desalinate a billion gallons for residential use. Those billion gallons mostly go down the drain inside the home, which makes its way back to the ocean after going to a wastewater treatment facility. The gallons that are actually consumed either end up back in the sewers after they wash through the body, or evaporate and return to the air, where they later return to the ocean in the form of rainwater.
There is no way to overall remove water from the ocean. The salinity level won't increase, because the water level won't decrease. The only things that dry up are remote lakes and rivers that are fed by snow/rain; the oceans are effectively the catch basin of the world.
"Using" water doesn't actually consume it, it just temporarily changes forms until it turns back into water and ends up back in the ocean (or some other area, like a desert aquifer).
